Herpes is a viral infection that requires antiviral medications such as aciclovir rather than antibiotics or steroids, as these are ineffective against viruses. Antibiotics such as amoxycillin with potassium clavulanate are only required if there is a secondary bacterial infection. Steroids such as betamethasone are not usually recommended unless specifically advised by your doctor.

Redness on the head of the penis can be a symptom of balanitis, which may be caused by a fungal or bacterial infection, poor hygiene, or an allergic reaction. It is best to have the area examined by a doctor to determine the exact cause before starting any treatment. Depending on the cause, the doctor may prescribe an antifungal, an antibiotic, or a mild steroid cream.
