WHY is this medicine prescribed?
Topical gentamicin is used in adults and children 1 year of age and older to treat skin infections caused by certain bacteria. Topical gentamicin is in a class of medications called antibiotics. It works by killing bacteria that cause infections.
HOW should this medicine be used?
Topical gentamicin comes as a cream and an ointment to apply to the skin. It is usually applied to the affected area 3 to 4 times a day. Use topical gentamicin at around the same times every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Use topical gentamicin exactly as directed. Do not use more or less of it or use it more often than prescribed by your doctor.
Topical gentamicin is only for use on the skin. Be careful not to get the medication in your eyes.
To use topical gentamicin, apply a small amount of medication to cover the affected area of skin with a thin, even film and rub in gently. The area may be covered with a gauze dressing or gelatin packing if your doctor has told you to do so.
If you are using topical gentamicin to treat impetigo contagiosa (a bacterial skin infection common in young children), gently remove any crusts from the infected skin before applying the medication.
Your symptoms should begin to improve during the first few days of treatment with topical gentamicin. If your symptoms do not improve or get worse, call your doctor.

What should I know about STORAGE and DISPOSAL of this medication?
Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom).
It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. http://www.upandaway.org
