This medication is used to treat minor skin infections (such as impetigo, folliculitis) or minor infections related to some skin conditions (such as eczema, psoriasis, minor burns/cuts/wounds). Gentamicin works by stopping the growth of certain bacteria. It belongs to a class of drugs known as aminoglycoside antibiotics.
This antibiotic only treats bacterial infections. It will not work for virus or fungus infections. Unnecessary use or overuse of any antibiotic can lead to its decreased effectiveness.
This medication is for use on the skin only.
Wash your hands before using. Clean and dry the affected area as directed. If you are treating impetigo, remove any dried, crusty skin to increase contact between the antibiotic and the infected area. Then gently apply a small amount of medication in a thin layer as directed by your doctor, usually 3 to 4 times a day. You may cover the area with a sterile gauze bandage if so directed. Keep the infected area clean. Wash your hands after use, unless you are using this product to treat the hands.
Dosage and length of treatment is based on your medical condition and response to treatment.
Use this medication regularly to get the most benefit from it. To help you remember, use it at the same times each day. Do not apply large amounts of this medication, use it more often, or use it for longer than prescribed. Your condition will not improve any faster, and your risk of side effects may increase.
Continue to use this medication for the full length of treatment prescribed, even if symptoms disappear after a few days. Stopping the medication too early may allow bacteria to continue to grow, which may result in a return of the infection.
Tell your doctor if your skin infection persists or if it worsens.
Skin irritation, redness, and itching may occur. If any of these effects persist or worsen, tell your doctor or pharmacist promptly.
