What ointment can cure herpes and ulcers on the glans?

Commonly used ointments for the treatment of glans herpes and ulcers include acyclovir cream, erythromycin ointment, mupirocin ointment, clotrimazole cream, and dexamethasone ointment. Detailed analysis is as follows:

1. Acyclovir Cream: For glans herpes and ulcers caused by viral infections, acyclovir cream directly inhibits the replication of herpes simplex virus or varicella-zoster virus, alleviates symptoms, shortens the course of illness, and serves as a core antiviral agent.

2. Erythromycin Ointment: Suitable for ulcers caused by bacterial infections, this ointment promotes healing of ulcerated areas through antibacterial and anti-inflammatory effects while preventing secondary infections, making it particularly appropriate for patients with bacterial balanitis.

3. Mupirocin Ointment: As an antibiotic ointment, it possesses both antibacterial properties and the ability to repair skin and mucous membranes. It effectively controls infections caused by Gram-positive cocci and accelerates ulcer healing.

4. Clotrimazole Cream: Used for ulcers caused by fungal infections such as candidal balanitis, this cream relieves symptoms by inhibiting fungal growth. It is often combined with circumcision in patients with phimosis or redundant foreskin.

5. Dexamethasone Ointment: When ulcers are triggered by allergies or inflammation, dexamethasone ointment helps reduce local inflammatory responses and relieve redness, swelling, and pain. However, dosage must be strictly controlled according to medical advice.

During treatment, keep the affected area clean and dry, avoid sexual activity and irritating foods, and wash daily with warm water followed by thorough drying. If there is no improvement within 72 hours of medication use, or if fever or spreading ulcers occur, seek immediate medical attention to rule out specific infections such as syphilis.
