BECLOMETHASONE + FUSIDIC ACID is a dermatological medication primarily used to treat bacterial skin infections, such as eczema and dermatitis. Bacterial infection occurs when harmful bacteria grow in the body and causes disease. It can infect any part of the body and multiply very quickly. Eczema is a condition in which skin patches become inflamed, itchy, cracked, and rough. Some types of eczema can also lead to blisters (a small bubble on the skin filled with serum and is caused by friction, burning, or other damage). Dermatitis is a skin condition that causes itchy, dry skin or a rash on swollen, reddened skin.
