Gentamicin is an aminoglycoside antibiotic obtained from cultures of Micromonospora purpurea. It is a mixture of the sulfate salts of Gentamicin C1, C2, C1a and C2a. All three components appear to have similar antimicrobial activity.
Gentamicin sulfate occurs as a white to buff powder and is soluble in water and insoluble in alcohol.
The structural formula is as follows:

WARNINGS
NOT FOR INJECTION INTO THE EYE
Gentamicin sulfate ophthalmic solution is not for injection. It should never be injected subconjunctivally, nor should it be directly introduced into the anterior chamber of the eye.
PRECAUTIONS
General
Prolonged use of topical antibiotics may give rise to overgrowth of nonsusceptible organisms including fungi. Bacterial resistance to gentamicin may also develop. If purulent discharge, inflammation or pain becomes aggravated, the patient should discontinue use of the medication and consult a physician. If irritation or hypersensitivity to any component of the drug develops, the patient should discontinue use of this preparation and appropriate therapy should be instituted.
Information for Patients
To avoid contamination, do not touch tip of container to the eye, eyelid or any surface.
Carcinogenesis, Mutagenesis, Impairment of Fertility
There are no published carcinogenicity or impairment of fertility studies on gentamicin. Aminoglycoside antibiotics have been found to be non-mutagenic.
Pregnancy
Gentamicin has been shown to depress body weights, kidney weights and median glomerular counts in newborn rats when administered systemically to pregnant rats in daily doses approximately 500 times the maximum recommended ophthalmic human dose. There are no adequate and well-controlled studies in pregnant women. Gentamicin should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.
ADVERSE REACTIONS
Bacterial and fungal corneal ulcers have developed during treatment with gentamicin ophthalmic preparations.
The most frequently reported adverse reactions are ocular burning and irritation upon drug instillation, non-specific conjunctivitis, conjunctival epithelial defects and conjunctival hyperemia.
Other adverse reactions which have occurred rarely are allergic reactions, thrombocytopenic purpura and hallucinations.
