Fusidic acid is an antibiotic and is used to treat bacterial skin infections. It can be used by adults and children to treat infections caused by staphylococcal bacteria such as impetigo, and infected cuts and grazes. Fusidic acid ointment is a similar medication, the only difference is that it’s a bit greasier therefore it’s normally only used on smaller areas of skin. The medication is only available on prescription. Fucidin H cream is a similar medication, it contains fusidic acid but has hydrocortisone (a corticosteroid) in addition. Fucidin H is used to treat inflammatory conditions that could also have a bacterial infection. It can be used for infected eczema and dermatitis. All these medications are only available on prescription.
You should follow the guidance given by your doctor but normally it is advised that you apply a small amount of fusidic acid cream or ointment to the affected area three or four times a day, Fucidin H cream is usually applied twice a day. The length of treatment is typically 1 to 2 weeks. Make sure you wash your hands well before and after using fusidic acid creams to prevent the infection from spreading to other parts of your body. Steroid-containing creams should not be used on any open skin, and on any sensitive areas of the body, such as the face.
Fusidic acid works by stopping the spread of bacterial skin infections. It does not kill the bacteria itself, instead, it stops the bacteria from producing important proteins, this prevents the bacteria from growing and replicating. The bacteria then either die on their own or are killed by your immune system.
Like all medications, don’t take them if you have previously had an allergic reaction to the medication, or if you have other medications or medical conditions where you would normally discuss with your doctor or pharmacist before starting something new. As with any medications, some people are bound to get some unwanted side effects. Some of the common ones include pain, irritation, stinging, redness, itching, swelling, and blistering at the site of application. Speak to your doctor if any of these side effects become bothersome.
Interactions are uncommon with fusidic acid products because only a small amount of medicine is absorbed into your bloodstream.
