The antibiotic to be taken for skin infections needs to be decided on the basis of the microorganisms responsible for the infection. Oral amoxicillin can be taken for bacterial infections, itraconazole for fungal infections, and metronidazole for parasitic infections. In the case of bacterial infections, such as impetigo, bacterial folliculitis, etc., oral amoxicillin capsules, or roxithromycin, cefaclor, minocycline hydrochloride, etc., can usually be taken. In the case of fungal infections of the skin, such as ringworm and nail fungus, oral itraconazole or terbinafine can be taken, and topical antifungal medications such as ketoconazole cream. In case of parasitic infections like helminthic mite infection, it can be treated with oral metronidazole and topical sulfur ointment or metronidazole gel. Therefore different antibiotics are used for different infections. It is recommended to actively seek medical attention and use medication under the guidance of a medical professional.
