$ 14.99Fucidin cream contains the active ingredient fusidic acid, which is an antibacterial agent used to treat a number of bacterial skin infections. Fucidin ointment contains sodium fusidate, which is the sodium salt of fusidic acid. Fusidic acid is a type of medicine called an antibiotic.
Fusidic acid works by preventing bacteria from producing proteins that are essential to them. Without these proteins the bacteria cannot grow, replicate and increase in numbers. Fusidic acid doesn’t directly kill the bacteria, but leaves them unable to increase in numbers. The remaining bacteria eventually die or are destroyed by the immune system. This treats the infection.
