Amoxicillin is effective when there is an infection in the wound. If a wound becomes infected, you should first go to the hospital in a timely manner and let the doctor check whether it is a local inflammation or a large area of pus below the wound. If it is a local inflammation, you can apply some local anti-inflammatory creams, such as fusidic acid, and then take oral amoxicillin to control the inflammation. Amoxicillin is a semi-synthetic broad-spectrum penicillin anti-inflammatory drug with strong bactericidal and anti-inflammatory effects. If there is a large area of pus below the wound, the wound needs to be opened and the pus cleaned out, and the necrotic tissue needs to be removed, and then appropriate bandages are applied, followed by oral amoxicillin. It should be noted that oral amoxicillin can only be taken if you are not allergic to penicillin-based drugs.
