Indications and Usage for Acuvue Theravision with Ketotifen

ACUVUE® Theravision™ with Ketotifen is a daily wear, daily disposable etafilcon A drug-eluting contact lens for prevention ocular itch due to allergic conjunctivitis and correction of refractive ametropia (myopia and hyperopia) in aphakic and/or phakic patients who do not have red eye(s), are suitable for contact lens wear and do not have more than 1 D of astigmatism.

The lens contains an H1 histamine receptor antagonist for the prevention of ocular itch due to allergic conjunctivitis. The prevention of itch has been demonstrated to last through 12 hours in clinical trials; however, the lens may be worn for longer than 12 hours in a single day.

Acuvue Theravision with Ketotifen Dosage and Administration

General Dosing Information

One ACUVUE® Theravision™ with Ketotifen should be inserted per eye per day. Discard lens after a single day''s use. ACUVUE® Theravision™ with Ketotifen may be worn beyond twelve hours for vision correction. Lenses should be removed prior to sleeping.

The maximum daily wearing time should be determined by the Eye Care Professional based upon the patient''s individual response to contact lenses. Patients tend to over wear the lenses initially. The Eye Care Professional should emphasize the importance of adhering to the initial maximum daily wearing time. Regular checkups, as determined by the Eye Care Professional, are also extremely important.

Eye drops containing benzalkonium chloride should not be used simultaneously with this product. Patients should wait 10 minutes after applying eye drop with benzalkonium chloride before inserting or reinserting lenses.

If the lens sticks (stops moving), the patient should be instructed to remove the lens. A few drops of non-preserved sterile saline solution may be applied directly to the eye to assist with removal. If non-movement of the lens continues after a few minutes, the patient should immediately consult their Eye Care Professional.

Do not use contact lens cleaning and disinfectant solutions with ACUVUE® Theravision™ with Ketotifen.

Contact Lens Fitting Information

See the ACUVUE® Theravision™ with Ketotifen Fitting Instruction Guide for professional fitting instructions and information.

Dosage Forms and Strengths

Daily disposable etafilcon A drug-eluting contact lens with ketotifen (19 mcg per lens).

Contraindications

Ocular Hyperemia

ACUVUE® Theravision™ with Ketotifen is contraindicated in patients with ocular hyperemia and should not be inserted into red or irritated eye(s). Remove Acuvue Theravision with Ketotifen immediately if eye(s) becomes red or irritated.

Corneal Hypoesthesia

Acuvue Theravision with Ketotifen is contraindicated in patients with decreased corneal sensation.

Corneal Infections

Acuvue Theravision with Ketotifen is contraindicated in patients with any corneal infection (bacterial, fungal, protozoal or viral).

Warnings and Precautions

Corneal Ulcers

Acuvue Theravision with Ketotifen should not be inserted if the patient has corneal epithelial breakdown, corneal ulceration, dry eye disease, injury or abnormality that affects the eyelids or anterior segment of the eye. Contact lens wear may worsen these conditions and lead to sight threatening complications. If a patient experiences eye discomfort, excessive tearing, vision changes, or redness of the eye, the patient should be instructed to immediately remove the lenses, and promptly contact the Eye Care Professional.

Studies have shown that when daily wear users wear their lenses overnight, the risk of ulcerative keratitis is greater than among those who do not wear them overnight. Contact lens wearers who are smokers have a higher incidence of corneal ulcers than nonsmokers.

Contact Lens-Related Complications

Acuvue Theravision with Ketotifen should not be used to treat or prevent lens-related symptoms including irritation, discomfort or redness. Acuvue Theravision with Ketotifen insertion could result in serious injury if a patient is experiencing these symptoms. Patients should be cautioned that proper use and care of contact lenses and lens care products are essential for the safe use of these products. If patients experience symptoms of contact lens intolerance or keratitis, the lens(es) should be IMMEDIATELY REMOVED.

Chemical Exposures

If chemicals of any kind (household products, gardening solutions, laboratory chemicals, etc.) are splashed into the eyes, the patient should: FLUSH EYES IMMEDIATELY WITH WATER AND IMMEDIATELY CONTACT THE EYE CARE PROFESSIONAL OR VISIT A HOSPITAL EMERGENCY ROOM WITHOUT DELAY.

Acanthamoeba Keratitis

Acuvue Theravision with Ketotifen should not be worn while swimming or in hot tubs. The lens should not be rinsed in water from the tap. Tap water contains many impurities that can contaminate or damage the lenses and may lead to eye infection or injury. Contact lens wear in these settings increases the risk of sight threatening eye infections from microorganisms.

Backup Spectacles

Eye Care Professionals should instruct the patient to always have a functional pair of spectacles with a current prescription available to use if the patient becomes unable to wear contact lenses, or in circumstances where contact lens wear is not advised.

Eye Protection

Patients should be advised to notify the employer of being a contact lens wearer. Some jobs may require the use of eye protection equipment or may require that the patient not wear contact lenses.

Concomitant Use of Eye Drops or Eye Medications

Eye Drops or Eye Medications containing benzalkonium chloride should not be used simultaneously with ACUVUE® Theravision™ with Ketotifen. Wait at least 10 minutes after eye drop application before inserting lenses.

Adverse Reactions

The following clinically significant adverse reactions are described elsewhere in the labeling:

• Ocular Hyperemia [see Contraindications (4.1)]
• Corneal Hypoesthesia [see Contraindications (4.2)]
• Corneal Infections [see Contraindications (4.3)]
• Corneal Ulcers [see Warnings and Precautions (5.1)]
• Contact Lens-Related Complications [see Warning and Precautions (5.2)]

USE IN SPECIFIC POPULATIONS

Pregnancy

Risk Summary

There are no adequate and well-controlled studies of ACUVUE® Theravison™ with Ketotifen administration in pregnant women to inform a drug-associated risk. ACUVUE® Theravison™ with Ketotifen is not absorbed systemically following ocular administration, and maternal use is not expected to result in fetal exposure to the drug. Oral administration of ketotifen fumarate to pregnant rats or rabbits did not produce teratogenicity at clinically relevant doses [see Data].

Data

Human Data

There are no human data that establish the presence or absence of drug-associated risk with the use of ACUVUE® Theravision™ with Ketotifen by pregnant women.

Animal Data

Oral administration of 45 mg/kg/day ketotifen to pregnant rabbits resulted in an increased incidence of retarded ossification of the sternebrae. This dose (normalized to body surface area) was approximately 23,000 times higher than the daily maximum recommended human ophthalmic dose (MRHOD) of 0.038 mg.

No adverse embryofetal effects were observed in rats or rabbits orally administered 100 mg/kg/day and 15 mg/kg/day, respectively, during organogenesis. These doses (normalized to body surface area) were approximately 26,000 and 7,700 times higher than the MRHOD, respectively.

An oral dose of 50 mg/kg/day ketotifen (approximately 13,000 times higher than MRHOD) administered to rats from Day 15 of pregnancy until Day 21 postpartum produced maternal toxicity, a slight increase in postnatal mortality and a slight decrease in body weight gain in offspring during the first four days post-partum.

Lactation

Risk Summary

There is no information regarding the presence or absence of ketotifen fumarate or its metabolites in human milk following use of ACUVUE® Theravision™ with Ketotifen, or on the breastfed infants and milk production. Ketotifen fumarate has been identified in breast milk in rats following oral administration. It is not known whether topical ocular administration could result in sufficient systemic absorption to produce detectable quantities in breast milk.

The development and health benefits of breastfeeding should be considered along with the mother''s clinical need for ACUVUE® Theravision™ with Ketotifen and any potential adverse effects on the breast-fed child from ketotifen fumarate.

Pediatric Use

The safety and efficacy of ACUVUE® Theravision™ with Ketotifen in pediatric patients below the age of 11 years has not been established.

Geriatric Use

Clinical studies of etafilcon A with ketotifen did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects.

Acuvue Theravision with Ketotifen - Clinical Pharmacology

Mechanism of Action

Device Component

In its hydrated state, the lens when placed on the cornea, acts as a refracting medium to focus light rays on the retina to correct refractive ametropia for as long as the lens is worn (up to 24 hours while awake).

Drug Component

Ketotifen fumarate, a benzocycloheptathiophene derivative, is a H1 receptor antagonist that stabilizes mast cells and prevents eosinophil accumulation. This action prevents the onset of ocular allergic itch allowing for continued lens wear during episodes of allergen exposure and has been demonstrated to last through 12 hours.

Nonclinical Toxicology

Carcinogenesis, Mutagenesis, Impairment of Fertility

Carcinogenesis

No information is available on the carcinogenic potential of ketotifen fumarate.

Mutagenesis

Ketotifen fumarate was determined to be non-mutagenic in a battery of in vitro and in vivo mutagenicity assays including: Ames test, in vitro chromosomal aberration test with V79 Chinese hamster cells, in vivo micronucleus assay in mouse, and mouse dominant lethal test. In addition, extracts of etafilcon A with ketotifen (19 mcg/lens) prepared in 0.9% sodium chloride or dimethyl sulfoxide were shown to be non-mutagenic in the Ames test.

Impairment of Fertility

Treatment of male rats with oral doses of ketotifen >10 mg/kg/day (approximately 2,600 times the MRHOD) for 70 days prior to mating resulted in mortality and a decrease in fertility. Treatment with ketotifen did not impair fertility in female rats receiving up to 50 mg/kg/day of ketotifen orally (approximately 13,000 times the MRHOD) for 15 days prior to mating.

Clinical Studies

The safety and efficacy of ACUVUE® Theravision™ with Ketotifen was assessed in two double-masked, randomized, placebo-controlled clinical conjunctival allergen challenge (CAC) studies (CR-4483 and CR-4484) and two 12-week safety studies (CR-4490 and CR-4539). Patients in these studies had allergic conjunctivitis induced by an ocular allergen challenge and refractive ametropia (myopia and hyperopia) suitable for contact lens wear without more than 1.00 D of astigmatism. A total of 244 patients (488 eyes) were evaluate in the CAC studies. A total of 491 subjects were exposed to ACUVUE® Theravision™ with Ketotifen over a period of 12 weeks in the safety studies. These four studies demonstrated that ACUVUE® Theravision™ with Ketotifen was safe and more effective than placebo (1•DAY ACUVUE®) in preventing ocular itching in patients with allergic conjunctivitis. ACUVUE® Theravision™ with Ketotifen reduced ocular itching within 3 minutes and the response was sustained for up to 12 hours after lens insertion. Visual acuity was comparable between ACUVUE® Theravision™ with Ketotifen and 1•DAY ACUVUE®.

Not all refractive powers, design configurations, or lens parameters available were tested in clinical investigation of the lenses. Therefore, when selecting an appropriate lens design, the Eye Care Professional should consider all characteristics of the lens that can affect lens performance and ocular health, including oxygen permeability, wettability, central and peripheral thickness and optic zone diameter. The potential impact of these factors on the patient''s ocular health should be carefully weighed against the patient''s need for refractive correction and prevention of itching associated with allergic conjunctivitis; therefore, the continuing ocular health of the patient and lens performance on the eye should be carefully monitored by the prescribing Eye Care Professional.

FITTING

GENERAL FITTING GUIDELINES

Patient Selection

You should first assess the patient''s needs to ensure that the patient is an appropriate candidate for ACUVUE® Theravision™ with Ketotifen. ACUVUE® Theravision™ with Ketotifen, like other soft contact lenses, will require the appropriate and usual physiological and diagnostic assessments necessary to ensure proper patient selection.

Pre-Fitting Examination

A pre-fitting patient history and examination are necessary to:

• Determine whether a patient is a suitable candidate for ACUVUE® Theravision™ with Ketotifen Contact Lens (consider allergies, patient hygiene and mental and physical state), and
• Take ocular measurements for the initial contact lens parameter selection, and
• Collect and record baseline clinical information to which post-fitting examination results can be compared.

A pre-fitting examination may include a determination of optimal distance and near spectacle correction and corneal curvature measurements. The near correction should be determined at the midpoint of the patient''s habitual reading distance. When more than one power provides optimal reading performance, prescribe the least plus (most minus) of the powers that meet the patient''s requirements.

Lens Selection

A. Initial Power Determination

A spectacle refraction should be performed to establish the patient''s baseline refractive status and to guide in the selection of the appropriate lens power. Remember to compensate for vertex distance if the refraction is greater than ±4.00 D.

B. Base Curve Selection (Trial Lens Fitting)

An 8.5mm/14.2mm ACUVUE® Theravision™ with Ketotifen Contact Lens should be the initial lens of choice for myopic patients regardless of keratometry readings. However, corneal curvature measurements should be performed to establish the patient''s baseline ocular status.

An 8.5mm/14.2mm ACUVUE® Theravision™ with Ketotifen Contact Lens should be placed on each of the patient''s eyes and evaluated after the patient has adjusted to the lenses. A properly fit lens will center and completely cover the cornea (i.e., no limbal exposure), have sufficient movement with the blink to provide tear exchange under the contact lens and be comfortable. The lens should move freely when manipulated digitally with the lower lid, and then return to its properly centered position when released. If resistance is encountered when pushing the lens up, the lens is fitting tightly and should not be dispensed to the patient.

A steep fitting lens may exhibit one or more of the following characteristics: insufficient movement with the blink, conjunctival indentation and resistance when pushing the lens up digitally with the lower lid. If the 8.5mm/14.2mm ACUVUE® Theravision™ with Ketotifen Contact Lens is judged to be steep fitting, it should not be dispensed to the patient.

A flat fitting lens may exhibit one or more of the following characteristics: decentration, incomplete corneal coverage (i.e., limbal exposure), excessive movement with the blink or edge standoff. If the 8.5mm/14.2mm ACUVUE® Theravision™ with Ketotifen Contact Lens is judged to be flat fitting, it should not be dispensed to the patient.

If the initial ACUVUE® Theravision™ with Ketotifen Contact Lens base curve is judged to be flat or steep fitting, the alternate base curve, if available, should be considered.

C. Final Lens Power

A spherical over-refraction should be performed to determine the final lens power after the lens fit is judged acceptable. The spherical over-refraction should be combined with the trial lens power to determine the final lens prescription.

Example 1:

Diagnostic lens: -2.00 D
Spherical over-refraction -0.25 D
Final lens power: -2.25 D

Example 2:

Diagnostic lens: -2.00 D
Spherical over-refraction +0.25 D
Final lens power: -1.75 D

MONOVISION FITTING GUIDELINES

Patient Selection

A. Monovision Needs Assessment

For a good prognosis the patient should have adequately corrected distance and near visual acuity in each eye. The amblyopic patient or the patient with significant astigmatism (greater than 1.00D) in one eye may not be a good candidate for monovision correction with the ACUVUE® Theravision™ with Ketotifen Contact Lens.

Occupational and environmental visual demands should be considered. If the patient requires critical vision (visual acuity and stereopsis), it should be determined by trial whether this patient can function adequately with monovision correction.

Monovision contact lens wear may not be optimal for such activities as:

(1)

Visually demanding situations such as operating potentially dangerous machinery or performing other potentially hazardous activities: and

(2)

Driving automobiles (e.g., driving at night). Patients who cannot pass their state drivers license requirements with monovision correction should be advised to not drive with this correction, OR may require that additional over-correction be prescribed

B. Patient Education

All patients do not function equally well with monovision correction. Patients may not perform as well for certain tasks with this correction as they have with bifocal reading glasses. Each patient should understand that monovision, as well as other presbyopic alternatives, can create a vision compromise that may reduce visual acuity and depth perception for distance and near tasks. During the fitting process it is necessary for the patient to realize the disadvantages as well as the advantages of clear near vision and straight ahead and upward gaze that monovision contact lenses provide.

Eye Selection

Generally, the non-dominant eye is corrected for near vision. The following two methods for eye dominance can be used.

A. Ocular Preference Determination Methods

Method 1 Determine which eye is the "sighting eye". Have the patient point to an object at the far end of the room. Cover one eye. If the patient is still pointing directly at the object, the eye being used is the dominant (sighting) eye.

Method 2 Determine which eye will accept the added power with the least reduction in vision. Place a hand-held trial lens equal to the spectacle near ADD in front of one eye and then the other while the distance refractive error correction is in place for both eyes. Determine whether the patient functions best with the near ADD lens over the right or left eye.

Other methods include the refractive error method and the visual demands method.

B. Refractive Error Method

For anisometropic correction, it is generally best to fit the more hyperopic (less myopic) eye for distance and the more myopic (less hyperopic) eye for near.

C. Visual Demands Method

Consider the patient''s occupation during the eye selection process to determine the critical vision requirements. If a patient''s gaze for near tasks is usually in one direction, correct the eye on that side for near.

Example:

A writer who places copy to the left side of the desk will function best with the near lens on the left eye.

SPECIAL FITTING CHARACTERISTICS

Near ADD Determination

Always prescribe the lens power for the near eye that provides optimal near acuity at the midpoint of the patient''s habitual reading distance. However, when more than one power provides optimal reading performance, prescribe the least plus (most minus) of the powers.

Trial Lens Fitting

A trial fitting is performed in the office to allow the patient to experience monovision correction. Lenses are fit according to the General Fitting Guidelines for base curve selection described in this guide.

Case history and standard clinical evaluation procedure should be used to determine the prognosis. Determine the distance correction and the near correction. Next determine the near ADD. With trial lenses of the proper power in place, observe the reaction to this mode of correction.

Allow the lenses to settle for about 20 minutes with the correct power lenses in place. Walk across the room and have the patient look at you. Assess the patient''s reaction to distance vision under these circumstances. Then have the patient look at familiar near objects such as a watch face or fingernails. Again assess the reaction. As the patient continues to look around the room at both near and distance objects, observe the reactions. Only after these vision tests are completed should the patient be asked to read print. Evaluate the patient''s reaction to large print (e.g., typewritten copy) at first and then graduate to newsprint and finally smaller type sizes.

After the patient''s performance, under the above conditions, is completed, tests of visual acuity and reading ability under conditions of moderately dim illumination should be attempted.

An initial unfavorable response in the office, while indicative of a guarded prognosis, should not immediately rule out a more extensive trial under the usual conditions in which a patient functions.

Adaptation

Visually demanding situations should be avoided during the initial wearing period. A patient may at first experience some mild blurred vision, dizziness, headaches and a feeling of slight imbalance. You should explain the adaptational symptoms to the patient. These symptoms may last for a brief minute or for several weeks. The longer these symptoms persist, the poorer the prognosis for successful adaptation.

To help in the adaptation process, the patient can be advised to first use the lenses in a comfortable familiar environment such as in the home.

Some patients feel that automobile driving performances may not be optimal during the adaptation process. This is particularly true when driving at night. Before driving a motor vehicle, it may be recommended that the patient be a passenger first to make sure that their vision is satisfactory for operating an automobile. During the first several weeks of wear (when adaptation is occurring), it may be advisable for the patient to only drive during optimal driving conditions. After adaptation and success with these activities, the patient should be able to drive under other conditions with caution.

Other Suggestions

The success of the monovision technique may be further improved by having your patient follow the suggestions below. Remember to advise patients to use only one ACUVUE® Theravision™ with Ketotifen Contact Lens per eye per day.

• Have a third contact lens (distance power) to use when critical distance viewing is needed.
• Have a third contact lens (near power) to use when critical near viewing is needed.
• Having supplemental spectacles to wear over the monovision contact lenses for specific visual tasks may improve the success of monovision correction. This is particularly applicable for those patients who cannot meet state driver licensing requirements with a monovision correction.
• Make use of proper illumination when carrying out visual tasks.

Success in fitting monovision can be improved by the following suggestions:

• Reverse the distance and near eyes if a patient is having trouble adapting.
• Refine the lens powers if there is trouble with adaptation. Accurate lens power is critical for presbyopic patients.
• Emphasize the benefits of clear near vision and straight ahead and upward gaze with monovision.

The decision to fit a patient with a monovision correction is most appropriately left to the Eye Care Professional in conjunction with the patient after carefully considering the patient''s needs.

PATIENT COUNSELING INFORMATION (PATIENT MANAGEMENT)

Dispensing Visit

• Evaluate the physical fit and visual acuity of the lens on each eye.
• Teach the patient how to insert and remove his or her lenses.
• Explain the daily wear regimen and schedule a follow-up examination.

Provide the patient with a copy of the ACUVUE® Theravision™ with Ketotifen patient instructions. Review these instructions with the patient so that he or she clearly understands the prescribed wearing and replacement schedule.

Review with the patient that no cleaning or disinfection is needed with daily disposable lenses. Patients should always dispose of lenses when they are removed and have spectacles or non-medicated lenses available.

Follow-Up Examinations

Follow-up care (necessary to ensure continued successful contact lens wear) should include routine periodic progress examinations, management of specific problems, if any, and a review with the patient of the wear schedule, lens replacement schedule, and proper lens care and handling procedures.

Recommended Follow-up Examination Schedule for ACUVUE® Theravision™ with Ketotifen for Daily Disposable Wear: (complications and specific problems should be managed on an individual patient basis):

• One week from the initial lens dispensing to patient.
• One month post-dispensing.
• Every three to six months thereafter.

NOTE: Preferably, at the follow-up visits, lenses should be worn for at least six hours.

Recommended Procedures for Follow-Up Visits:

• Solicit and record patient''s symptoms, if any.
• Measure visual acuity monocularly and binocularly at distance and near with the contact lenses.
• Perform an over-refraction at distance and near to check for residual refractive error.
• With the biomicroscope, judge the lens fitting characteristics (as described in the "General Fitting Guidelines") and evaluate the lens surface for deposits and damage.
• Following lens removal, examine the cornea and conjunctiva with the biomicroscope and fluorescein.
  • The presence of vertical corneal striae in the posterior central cornea and/or corneal neovascularization is indicative of excessive corneal edema.
  • The presence of corneal staining and/or limbal-conjunctival hyperemia can be indicative of an unclean lens, a reaction to solution preservatives, excessive lens wear and/or a poorly fitting lens.
  • Papillary conjunctival changes may be indicative of an unclean and/or damaged lens.
• Periodically perform keratometry and spectacle refractions. The values should be recorded and compared to the baseline measurements.

If any observations are abnormal, use professional judgment to alleviate the problem and restore the eye to optimal conditions. If the criteria for successful fit are not satisfied during any follow-up examinations, repeat the patient''s trial fitting procedure and refit the patient.

WEARING SCHEDULE (DAILY WEAR)

DOSAGE AND ADMINISTRATION

• Insert one lens per eye per day. Discard lens after a single day''s use.
• If prevention or relief of itching is needed beyond twelve hours, remove ACUVUE® Theravision™ with Ketotifen and consult your eye care professional.
• ACUVUE® Theravision™ with Ketotifen may be worn beyond twelve hours for vision correction. Lenses should be removed prior to sleeping.

ADDITIONAL INFORMATION

• The maximum daily wearing time should be determined by the Eye Care Professional based upon the patient''s individual response to contact lenses. Regular checkups, as determined by the Eye Care Professional, are also extremely important.
• Patients tend to over wear the lenses initially. The Eye Care Professional should emphasize the importance of adhering to the initial maximum daily wearing time. Maximum wearing time should be determined by the Eye Care Professional based upon the patient''s physiological eye condition, because individual response to contact lenses varies.
• ACUVUE® Theravision™ with Ketotifen is intended to be worn once on a daily disposable basis (less than 24 hours, while awake) and should be discarded upon removal. Studies have not been performed to show that ACUVUE® Theravision™ with Ketotifen is safe to wear during sleep.
• Patients should never wear lenses beyond the period recommended by the Eye Care Professional.

REPLACEMENT SCHEDULE

• These lenses are indicated for disposable wear and should be discarded upon removal.

LENS CARE DIRECTIONS

For Lenses Prescribed for Single Use Disposable Wear:

• The Eye Care Professional should review with patients that no cleaning or disinfection is needed with disposable lenses. Patients should always dispose of lenses when they are removed and have replacement non-medicated lenses or spectacles available.

Care for Sticking (Non-Moving) Lenses

• During removal, if the lens sticks to the eye, the patient should be instructed to apply a few drops of non-preserved sterile saline solution directly to the eye and wait until the lens begins to move freely on the eye before removing it. If non-movement of the lens continues after a few minutes, the patient should immediately contact the Eye Care Professional.

STORAGE CONDITIONS

Store at 15°C to 25°C (59°F to 77°F); with excursions permitted up to 30°C (86°F).

Specific Instructions for Use and Warnings:

Water Activity

Instruction for Use

Do not expose your contact lenses to water while you are wearing them.

WARNING:

Water can harbor microorganisms that can lead to severe infection, vision loss, or blindness. If your lenses have been submersed in water when participating in water sports or swimming in pools, hot tubs, lakes, or oceans, you should discard them and replace them with a new pair. Ask your Eye Care Professional for recommendations about wearing your lenses during any activity involving water.

PRECAUTIONS

For your eye health, it is important to carefully follow the handling, insertion, removal, and wearing instructions in this booklet, as well as those prescribed by your Eye Care Professional (see "Lens Handling & Insertion", "Lens Wearing" and "Caring for your Lenses" sections).

General Precautions:

Do Not use contact lens care solutions with this product

If you wear your contact lenses to correct presbyopia using monovision you may not be able to get the best corrected visual acuity for either far or near vision. Visual needs are different for different people, so your Eye Care Professional should work with you when selecting the most appropriate type of lens for you.

Always contact your Eye Care Professional before using any medicine in your eyes.

Be aware that certain medications, such as antihistamines, decongestants, diuretics, muscle relaxants, tranquilizers, oral contraceptives, and those for motion sickness may cause dryness of the eye, increased lens awareness (feeling of the lens in the eye), or blurred vision. Always inform your Eye Care Professional if you experience any problems with your lenses while taking such medications.

Do not change lens type (e.g. brand name, etc.) or parameters (e.g. diameter, base curve, lens power, etc.) without consulting your Eye Care Professional.

Consult your Eye Care Professional or Health Care Provider if you are pregnant or nursing a baby.

As with any contact lens, follow-up visits are necessary to assure the continuing health of your eyes. Ask your Eye Care Professional about the recommended follow-up schedule.

Who Should Know That You are Wearing Contact Lenses:

Inform all of your doctors (Health Care Professionals) about being a contact lens wearer.

Always inform your employer of being a contact lens wearer. Some jobs may require use of eye protection equipment or may require that you not wear contact lenses.

ADVERSE REACTIONS

(POSSIBLE PROBLEMS WITH LENS WEAR AND WHAT TO DO)

Possible Problems

The most commonly observed ocular adverse reactions in clinical studies, occurring in < 2% of treated eyes, were eye irritation, eye pain, and instillation site irritation.

Other potential lens related side effects are discussed in greater detail in other sections of this guide:

Risk of Developing Corneal Ulcers (See WARNINGS)

Other Contact Lens Related Problems

Be aware that problems can occur while wearing contact lenses and may be associated with the following symptoms:

• burning, stinging, itchy, and/or dry eyes
• reduced lens comfort
• feeling of something in your eye (foreign body, scratched area)
• swelling or inflammation in or around the eyes
• eye redness
• eyelid problems
• watery eyes and/or unusual eye secretion
• poor vision
• blurred vision
• rainbows or halos around objects
• sensitivity to light (photophobia)

When any of the above symptoms occur, a serious eye condition may be present. You should immediately be seen by your Eye Care Professional, so that the problem can be identified and treated, if necessary, in order to avoid serious eye damage.

This product should not be used to treat or prevent lens-related symptoms including irritation, discomfort, or redness.

Recognizing Problems and What To Do

You should conduct a simple 3-part self-examination at least once a day. Ask yourself:

-

How do the lenses feel on my eyes?

-

How do my eyes look?

-

Have I noticed a change in my vision?

If you notice any problems, you should IMMEDIATELY REMOVE YOUR LENS AND CONTACT YOUR EYE CARE PROFESSIONAL.

LENS HANDLING AND INSERTION

For your eye health, it is important to carefully follow the handling, insertion, removal, and wearing instructions in this booklet, as well as those prescribed by your Eye Care Professional. If you will not or cannot always follow the recommended care procedures, you should not attempt to wear contact lenses.

When you first get your lenses, be sure that you are able to put the lenses on and remove them (or have someone else available who can remove the lenses for you) before leaving your Eye Care Professional''s office.

Step 1: Getting Started

It is essential that you learn and use good hygiene in the care and handling of your new lenses.

Cleanliness is the first and most important aspect of proper contact lens care. In particular, your hands should be clean, dry, and free of any soaps, lotions, or creams before you handle your lenses.

Before you start:

Always wash your hands thoroughly with a mild soap, rinse completely, and dry with a lint-free towel before touching your lenses.

You should avoid the use of soaps containing cold cream, lotion, or cosmetics before handling your lenses. These substances may come into contact with the lenses and interfere with successful wearing. It is best to put on your lenses before putting on makeup

Step 2: Opening the Packaging

Multi-pack

Always confirm the lens parameters (e.g. diameter (DIA), base curve (BC), lens power (D), etc.) printed on the multi-pack and on the individual lens package match your prescription. DO NOT use if there is a mismatch.

Each multi-pack contains individually packaged lenses. Each lens comes in its own lens package designed specifically to keep it sterile while sealed.

These lenses are sensitive to light – store individual blister packages in the carton until use.

Lens Package

DO NOT use if the sterile blister package is opened or damaged.

To open an individual lens package, follow these simple steps:

1. Shake the lens package and check to see that the lens is floating in the solution.
2. Carefully peel back the foil closure to reveal the lens.
3. Place a finger on the lens and slide the lens up the side of the bowl of the lens package until it is free of the container.

Occasionally, a lens may stick to the inside surface of the foil when opened, or to the plastic package itself. This will not affect the sterility of the lens. It is still perfectly safe to use. Carefully remove and inspect the lens following the handling instructions.

NEVER use tweezers or other tools to remove your lenses from the lens container.

Lens Handling Tips

• Handle your lenses with your fingertips, and be careful to avoid contact with fingernails. It is helpful to keep your fingernails short and smooth.
• Develop the habit of always working with the same lens first to avoid mix-ups.
• After you have removed the lens from the packaging, examine it to be sure that it is a single, moist, clean lens that is free of any nicks or tears. If the lens appears damaged, DO NOT use it.

Step 3: Placing the Lens on the Eye

Remember, always start with the same eye.

Once you have opened the lens package, removed, and examined the lens, follow these steps to insert the lens into your eye:

1. BE SURE THE LENS IS NOT INSIDE-OUT by following one of the following procedures:
   • Place the lens on the tip of your index finger and check its profile. The lens should assume a natural, curved, bowl-like shape. If the lens edges tend to point outward, the lens is inside out.
   • Gently squeeze the lens between the thumb and forefinger. The edges should turn inward. If the lens is inside out, the edges will turn slightly outward.
     OR
   • Place the lens on the tip of your index finger and, looking up at the lens, locate the numbers 1-2-3. 1-2-3 indicates correct orientation, while a reverse of 1-2-3 indicates the lens is inside out. If the lens is inside out (reverse 1-2-3), invert the lens and locate the numbers again to confirm correct lens orientation.
2. With the lens on your index finger, use your other hand to hold your upper eyelid so you won''t blink.
3. Pull down your lower eyelid with the other fingers of your "inserting" hand.
4. Look up at the ceiling and gently place the lens on the lower part of your eye.
5. Slowly release your eyelid and close your eye for a moment.
6. Blink several times to center the lens.
7. Use the same technique when inserting the lens for your other eye.

There are other methods of lens placement. If the above method is difficult for you, ask your Eye Care Professional for an alternate method.

Step 4: Checking Your Lenses

After you have successfully inserted your lenses, you should ask yourself:

• Do I see well?
• How do the lenses feel on my eyes?
• How do my eyes look?

If after placement of the lens, your vision is blurred, check for the following:

The lens is not centered on the eye (see "Step 5: Centering the Lens," next in this booklet).

If the lens is centered, remove the lens (see "Removing Your Lenses") and check for the following:

–

Cosmetics or oils on the lens. Dispose of the lens and insert a new fresh lens.

–

The lens is on the wrong eye.

–

The lens is inside out (it would also not be as comfortable as normal). See "Step 3: Placing the Lens on the Eye."

If you find that your vision is still blurred after checking the above possibilities, remove the lens and consult your Eye Care Professional.

Note: If a lens is noticeably uncomfortable upon insertion or becomes less comfortable than when it was first inserted, remove the lens immediately and contact your Eye Care Professional. If your examination of your eyes and the lenses shows any other problems, IMMEDIATELY REMOVE YOUR LENSES AND CONTACT YOUR EYE CARE PROFESSIONAL.

Step 5: Centering the Lens

A lens, which is on the cornea (center of your eye), will very rarely move onto the white part of the eye during wear. This, however, can occur if insertion and removal procedures are not performed properly. To center a lens, follow either of these procedures:

• Close your eyelids and gently massage the lens into place through the closed lids.
  OR
• Gently move the off-centered lens onto the cornea (center of your eye) while the eye is opened using finger pressure on the edge of the upper lid or lower lid.

LENS WEARING

While wearing your lenses, remember the following important precautions:

Hazardous Conditions

If you use aerosol (spray) products, such as hair-spray, while wearing lenses, keep your eyes closed until the spray has settled.

Avoid all harmful or irritating vapors and fumes while wearing lenses.

Never rinse your lenses in water from the tap. Tap water contains many impurities that can contaminate or damage your lenses and may lead to eye infection or injury.

Water Activity

• Do not expose your contact lenses to water while you are wearing them.

Lubricating/Rewetting Solutions

Lubricating/Rewetting Solutions should not be used with these lenses. If the lens sticks (stops moving), a few drops of non-preserved sterile saline may be applied to assist with removal.

Do not use saliva or anything other than the recommended solutions for lubricating or rewetting your lenses. Do not put lenses in your mouth.

Sharing Lenses

Never allow anyone else to wear your lenses. Sharing lenses greatly increases the chance of eye infections.

Adhering to the Prescribed Wearing & Replacement Schedules

Never wear your lenses beyond the amount of time recommended by your Eye Care Professional. Never wear more than one lens per day.

Always throw away worn lenses as prescribed by your Eye Care Professional.

REMOVING YOUR LENSES

CAUTION: Always be sure the lens is on the cornea (center of your eye) before attempting to remove it. Determine this by covering the other eye. If vision is blurred, the lens is either on the white part of the eye or it is not on the eye at all. To locate the lens, inspect the upper area of the eye by looking down into a mirror while pulling the upper lid up. Then inspect the lower area by pulling the lower lid down.

1. Wash, rinse, and dry your hands thoroughly. You should follow the method that is recommended by your Eye Care Professional. Below is an example of one method: the Pinch Method.

   Pinch Method:

   Step 1. Look up, slide the lens to the lower part of the eye using the forefinger.

   Step 2. Gently pinch the lens between the thumb and forefinger.

   Step 3. Remove the lens.

2. Follow the instructions in the next section, "Caring for Your Lenses".

NOTE: For your eye health, it is important that the lens moves freely on your eye. If the lens sticks (stops moving) on your eye, apply a few drops of the recommended rewetting solution. Wait until the lens begins to move freely on the eye before removing it. If non-movement of the lens continues, you should immediately consult your Eye Care Professional.

CARING FOR YOUR LENSES

Remember, there is no cleaning or disinfection needed with these lenses. Always dispose of lenses when they are removed and have replacement non-medicated lenses or glasses available. Any unused product or waste material should be disposed of in accordance with local requirements.

Lens Storage:

• Store these lenses at room temperature
• These lenses are sensitive to light – store individual blister packages in the carton until use.

EMERGENCIES

If chemicals of any kind (household products, gardening solutions, laboratory chemicals, etc.) are splashed into your eyes: FLUSH EYES IMMEDIATELY WITH TAP WATER AND IMMEDIATELY CONTACT YOUR EYE CARE PROFESSIONAL OR VISIT A HOSPITAL EMERGENCY ROOM RIGHT AWAY.

INSTRUCTIONS FOR THE PRESBYOPIC PATIENT

The decision to be fit with monovision correction is most appropriately left to your Eye Care Professional, in conjunction with you, after carefully considering and discussing your needs.

Pronunciation: a-SYE-klo-veer
Generic name: acyclovir (oral)
Brand names: Sitavig, Zovirax
Drug class: Purine nucleosides

Medically reviewed by Melisa Puckey, BPharm. Last updated on Dec 14, 2022.

What is acyclovir?

Acyclovir is an antiviral drug that is used to treat symptoms of shingles, chickenpox, cold sores and genital herpes which are all caused by herpes viruses. It is also used to prevent having regular outbreaks of genital herpes. Acyclovir will not get rid of the virus infection but does help sores heal faster and helps with pain relief.

Warnings

Take acyclovir for the entire length of time prescribed by your doctor. Your symptoms may get better before the infection is completely treated.

Treatment with acyclovir should be started as soon as possible after the first appearance of symptoms (such as tingling, burning, blisters).

Herpes infections are contagious and you can infect other people, even while you are being treated with acyclovir. Avoid letting infected areas come into contact with other people. Avoid touching an infected area and then touching your eyes. Wash your hands frequently to prevent passing the infection to others.

Before taking this medicine

You should not take this medicine if you are allergic to acyclovir or valacyclovir (Valtrex). You should not take acyclovir buccal tablets (Sitavig) if you are allergic to milk proteins.

To make sure this medicine is safe for you, tell your doctor if you have:

• kidney disease; or

• a weak immune system (caused by disease or by using certain medicine).

Tell your doctor if you are pregnant or breastfeeding.

Herpes can be passed to your baby during childbirth if you have a genital lesion when your baby is born. If you have genital herpes, it is very important to prevent herpes lesions during pregnancy. Take your medicine as directed to best control your infection.

It may not be safe to breastfeed while using this medicine. Ask your doctor about any risk.

Acyclovir should not be given to a child younger than 2 years old.

How should I take acyclovir?

Take acyclovir exactly as prescribed by your doctor. Follow all directions on your prescription label and read all medication guides or instruction sheets.

Start taking acyclovir as soon as possible after the first appearance of symptoms (such as tingling, burning, blisters). Start taking Sitavig within 1 hour after you first notice sold core symptoms, before the cold sore appears.

Read and carefully follow any Instructions for Use provided with your medicine. Ask your doctor or pharmacist if you do not understand these instructions.

Do not crush, chew, suck on, or swallow a buccal tablet. Place the flat side of the tablet against your upper gum, on the same side of the mouth as your cold sore. Allow the tablet to dissolve in your mouth throughout the day. You may eat and drink normally while the buccal tablet is in place.

Do not give an acyclovir buccal tablet to a young child or choking could occur.

Shake the oral suspension (liquid) before you measure a dose. Use the dosing syringe provided, or use a medicine dose-measuring device (not a kitchen spoon).

Acyclovir doses are based on weight (especially in children and teenagers). Your dose needs may change if you gain or lose weight.

Drink plenty of water while you are taking this medicine to keep your kidneys working properly.

Use this medicine for the full prescribed length of time, even if your symptoms quickly improve. Skipping doses may increase the risk of your virus becoming resistant to medication.

Lesions caused by herpes viruses should be kept as clean and dry as possible. Wearing loose clothing may help to prevent irritation of the lesions.

Store at room temperature away from moisture and heat.

What happens if I miss a dose?

Take the medicine as soon as you can, but skip the missed dose if it is almost time for your next dose. Do not take two doses at one time.

What happens if I overdose?

Seek emergency medical attention or call the Poison Help line at 1-800-222-1222.

What to avoid

Avoid brushing your teeth, chewing gum, or wearing an upper denture while you have a buccal tablet in your mouth. You may rinse your mouth gently. Drink plenty of liquids to prevent dry mouth.

Herpes infections are contagious and you can infect other people, even while you are being treated with acyclovir. Avoid letting infected areas come into contact with other people. Avoid touching an infected area and then touching your eyes. Wash your hands frequently to prevent passing the infection to others.

Taking acyclovir will not prevent you from passing genital herpes to your sexual partner. Avoid sexual intercourse while you have active lesions or the first symptoms of an outbreak. Genital herpes may still be contagious through "viral shedding" from your skin, even if you have no symptoms.

Acyclovir side effects

Get emergency medical help if you have signs of an allergic reaction to acyclovir: hives; difficult breathing; swelling of your face, lips, tongue, or throat.

Call your doctor at once if you have:

• easy bruising or bleeding, purple or red pinpoint spots under your skin;

• changes in behavior;

• confusion, hallucinations; or

• signs of a kidney problem - little or no urinating; painful or difficult urination; swelling in your feet or ankles; feeling tired or short of breath.

Common acyclovir side effects may include:

• mild skin pain;

• rash, itching;

• nausea, vomiting, diarrhea;

• headache; or

• mouth pain while using an acyclovir buccal tablet.

This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.

What other drugs will affect acyclovir?

Acyclovir can harm your kidneys, especially if you also use certain medicines for infections, cancer, osteoporosis, organ transplant rejection, bowel disorders, high blood pressure, or pain or arthritis (including Advil, Motrin, and Aleve).

Other drugs may interact with acyclovir, including prescription and over-the-counter medicines, vitamins, and herbal products. Tell your doctor about all your current medicines and any medicine you start or stop using.

Where can I get more information?

Remember, keep this and all other medicines out of the reach of children, never share your medicines with others, and use acyclovir only for the indication prescribed.

Frequently asked questions

• Can you drink alcohol while taking acyclovir?
• What would be the benefits of taking valacyclovir vs acyclovir?
