For a bacterial infection on the foreskin (bacterial balanitis), treatment typically involves a prescription topical antibiotic cream, such as mupirocin or fusidic acid, applied to the clean, dry affected area. Practising good hygiene by gently washing with warm water and drying thoroughly is also essential. If the infection is severe, a healthcare provider might prescribe oral antibiotics like cephalexin. Since fungal infections (thrush) can look similar and require different treatment, it is important to see a doctor for a proper diagnosis before starting medication. Rest assured, this is a very common, easily treatable condition.
