Uses for Zymar
Bacterial Ophthalmic Infections
Many cases of mild, acute bacterial conjunctivitis resolve spontaneously without anti-infective therapy.6 17 18 19 Although topical ophthalmic anti-infectives may shorten time to resolution and reduce severity and risk of complications,6 8 17 18 19 avoid indiscriminate use of topical anti-infectives.6 17
Treatment of acute bacterial conjunctivitis generally is empiric;6 17 18 use of a broad-spectrum topical ophthalmic antibacterial usually recommended.6 17 18 In vitro staining and/or cultures of conjunctival material may be indicated in diagnosis and management of recurrent, severe, or chronic purulent conjunctivitis or when acute conjunctivitis does not respond to initial empiric topical treatment.6 17 18
Zymar Dosage and Administration
Bacterial Ophthalmic Infections
Children ≥1 year of age: Instill 1 drop of 0.5% solution in the affected eye(s) every 2 hours while awake (up to 8 times daily) on day 1, then 1 drop 2–4 times daily while awake on days 2 through 7.1 2
Bacterial Ophthalmic Infections
Cautions for Zymar
Hypersensitivity to gatifloxacin, other quinolones, or any ingredient in the formulation.1
Hypersensitivity reactions, including anaphylactic reactions, angioedema (e.g., pharyngeal, laryngeal, or facial edema), dyspnea, urticaria, and itching, reported in patients receiving gatifloxacin ophthalmic solution.1 Stevens-Johnson syndrome reported rarely.1
Hypersensitivity reactions have occurred following a single dose.1
Immediately discontinue at first sign of rash or hypersensitivity reaction.1
Corneal endothelial cell injury may occur if gatifloxacin ophthalmic solution is introduced directly into anterior chamber of the eye.1
Do not wear contact lenses during treatment with gatifloxacin ophthalmic solution or if any signs or symptoms of bacterial conjunctivitis are present.2
Common Adverse Effects
Interactions for Zymar
No formal drug interaction studies using gatifloxacin 0.5% ophthalmic solution.2
Serum concentrations of gatifloxacin were undetectable (<5 ng/mL) after topical application to one eye of gatifloxacin 0.5% ophthalmic solution in an escalated dosage regimen (2 drops initially, then 2 drops 4 times daily for 7 days, and then 2 drops 8 times daily for 3 days).1 2
Actions and Spectrum
Spectrum of activity includes gram-positive aerobic bacteria and some gram-negative aerobic bacteria.1
Advice to Patients
Advise patients not to wear contact lenses during treatment with gatifloxacin ophthalmic solution or if any signs or symptoms of bacterial conjunctivitis are present.2
Advise patients to immediately discontinue gatifloxacin ophthalmic solution and contact a clinician at first sign of rash or hypersensitivity reaction.1
