Brand names: Gentamicin sulfate (ophthalmic)
Gentamicin sulfate is an antibiotic. This form of gentamicin is an ophthalmic (applied directly in the eye) medication that is prescribed to treat infections such as conjunctivitis (pinkeye) and other eye infections.
To help clear up your infection completely, keep using gentamicin eyedrops or eye ointment for the full time of treatment, even if your symptoms have disappeared. Do not allow anyone else to use Gentamicin sulfate (ophthalmic), and do not save it for use on another infection.
Use Gentamicin sulfate (ophthalmic) exactly as prescribed. To administer gentamicin, follow these steps:
Your vision may be blurred for a few minutes following application of the ointment.
Occasional eye irritation—with itching, redness and swelling—may occur with use of the eyedrops. Occasional burning or stinging in the eye may occur with use of the ointment.
If you are sensitive to or have ever had an allergic reaction to gentamicin or certain other antibiotics, such as tobramycin, you should not take Gentamicin sulfate (ophthalmic). Make sure your doctor is aware of any drug reactions you have experienced.
Continued or prolonged use of Gentamicin sulfate (ophthalmic) may result in a growth of bacteria or fungi that do not respond to Gentamicin sulfate (ophthalmic) and can cause a second infection. Should this occur, notify your doctor.
Ophthalmic ointments may slow corneal healing.
If gentamicin is used with certain other drugs, the effects of either could be increased, decreased, or altered. Always check with your doctor before combining gentamicin with other medications.
There are no special recommendations for Gentamicin sulfate (ophthalmic). If you are pregnant or plan to become pregnant, ask your doctor for the best advice in your personal situation.
