Why is this medication prescribed?

Gentamicin topical is prescribed for the treatment of certain skin infections caused by bacteria. It is commonly used to treat conditions such as impetigo (a bacterial skin infection), infected wounds, and other bacterial skin infections. Gentamicin belongs to a class of antibiotics known as aminoglycosides, which work by inhibiting the growth of bacteria.

How should this medicine be used?

Here’s how gentamicin topical is typically used:

• Clean the affected area: Before applying gentamicin topical, clean the affected area with mild soap and water and pat it dry.
• Apply a thin layer: Apply a thin layer of gentamicin topical cream or ointment to cover the affected area.
• Frequency: Gentamicin topical is usually applied 2 to 4 times daily, depending on the severity of the infection and your doctor’s instructions.
• Avoid contact with eyes, nose, and mouth: Be careful to avoid getting the medication in your eyes, nose, or mouth. If accidental contact occurs, rinse thoroughly with water.
• Do not cover with airtight dressings unless instructed: In some cases, your doctor may recommend covering the treated area with a bandage or dressing. Follow your doctor’s instructions regarding this.
• Continue treatment as prescribed: Even if symptoms improve, continue using gentamicin topical for the full course of treatment as prescribed by your doctor. Stopping treatment too soon may allow the infection to return or worsen.
• Follow up with your doctor: If your symptoms do not improve or if they worsen during treatment, contact your doctor.

It’s important to use gentamicin topical exactly as directed by your doctor. Do not use it more frequently or for a longer period than prescribed, as this can increase the risk of side effects and antibiotic resistance. If you have any questions or concerns about how to use gentamicin topical, consult your doctor or pharmacist for further guidance.

What side effects can this medication cause?

Gentamicin topical, like any medication, can cause side effects, although not everyone experiences them. Common side effects of gentamicin topical may include:

• Skin irritation: This may include redness, itching, burning, stinging, or rash at the site of application.
• Allergic reactions: Some individuals may experience an allergic reaction to gentamicin topical, which can manifest as severe skin irritation, swelling, or hives. In rare cases, allergic reactions may be severe and require immediate medical attention.
• Contact dermatitis: Prolonged or repeated use of gentamicin topical may lead to contact dermatitis, characterized by redness, dryness, scaling, or blistering of the skin.
• Overgrowth of non-susceptible organisms: Prolonged use of gentamicin topical may lead to the overgrowth of bacteria or fungi that are not susceptible to gentamicin, resulting in secondary infections.
• Nephrotoxicity and ototoxicity: While systemic absorption of gentamicin from topical application is minimal, it can still occur, especially if applied to large areas of damaged skin or mucous membranes. In such cases, systemic absorption may lead to kidney damage (nephrotoxicity) or hearing loss (ototoxicity). However, these side effects are rare with topical use.

It’s essential to report any unusual or severe side effects to your doctor promptly. If you experience signs of an allergic reaction, such as difficulty breathing, swelling of the face, lips, tongue, or throat, or severe skin irritation, seek immediate medical attention.
