Impetigo. Impeitgo is a skin infection usually caused by strp and staph bacteria. It is contagious and if untreated, may cause significant complications. If you only have a few spots, the surer way of trreatment is mupirocin, prescribed by your doctor, to apply on the sores. More widespread lesions should be treated with oral antibiotics.
Impetigo. Antibiotics which can be helpful include penicillin derivatives (such as augmentin) and cephalosporins such as Cephalexin (keflex). If clinical suspicion supported by culture results show other bacteria, such as drug-resistant staph (methicillin-resistant staphylococcus aureus or mrsa), other antibiotics such as Clindamycin or trimethoprim-sulfamethoxazole (bactrim (sulfamethoxazole and trimethoprim) or septra) are used.
OTC. If you truly have impetigo, you can treat the infection with Bacitracin or neosporin ointment 3 times a day.
