Penile blisters can be improved under a doctor's guidance by applying acyclovir ointment externally and taking valacyclovir tablets or acyclovir tablets orally. If the blisters appear near the foreskin and glans, accompanied by local ulceration, redness, swelling, or itching, topical metronidazole may be used for treatment as directed by a physician. In daily life, it is recommended to wear cotton underwear, bathe regularly, and maintain good hygiene.
