Gentamicin Topical Dosage
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 it 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 it 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.
Do not let anyone else take your medication. Your prescription is probably not refillable. If you still have symptoms of infection after you finish topical gentamicin, call your doctor.
It is important for you to keep a written list of all of the prescription and nonprescription (over-the-counter) medicines you are taking, as well as any products such as vitamins, minerals, or other dietary supplements. You should bring this list with you each time you visit a doctor or if you are admitted to a hospital. It is also important information to carry with you in case of emergencies.
