If you have a skin infection, your doctor may prescribe medicine. What he gives you depends on the type of infection:
Any break in the skin can lead to a tetanus infection if your tetanus shot isn’t up to date. Check with your doctor to see if you need a booster one.
Antibiotics fight a bacterial infection.
Antivirals treat viral infections.
Antifungal creams, ointments, or powders treat fungal infections.
