Gentamicin sulfate cream is a topical antibiotic used to treat various skin infections caused by bacteria, including folliculitis and impetigo, according to MedicineNet. It is also used for treating infections caused by some skin conditions such as psoriasis and eczema, and infections that arise from wounds, cuts and minor burns. The brand name for gentamicin sulfate cream is Gentak.
The cream is classified as an aminoglycoside antibiotic, and the way that gentamycin works is by halting the growth of particular bacteria. The cream form is usually used for oozing, greasy or wet infection types, while the ointment form of the gentamycin is used for dry skin infections and keeps moisture in the skin.
Gentamycin is useful only in treating bacterial infections, states MedicineNet. It is not used for treating fungal or viral infections.
Before applying gentamicin sulfate cream, wash and completely dry the area. Rub the cream onto the infection, then cover it with gauze. Gentamicin sulfate cream is administered in doses, but a dosage should not be doubled if a dosage is missed. Gentamicin sulfate cream can make users more susceptible to sunburn, and long-term use could cause a second infection. Do not use the cream if the patient is allergic to any ingredient that it contains.
