Zoster Cream

Zoster Cream contains Acyclovir (5% w/w) and is prescribed for the treatment of viral skin infections caused by the herpes virus, including herpes simplex (cold sores, genital herpes), and herpes zoster (shingles). It belongs to the class of antiviral medicines that work by stopping the virus from multiplying in the skin cells. While it does not cure herpes infections, it helps reduce symptoms such as pain, burning, itching, and blistering, and speeds up the healing of sores.

Not everyone using Zoster Cream will experience side effects, but some may notice temporary skin irritation, redness, dryness, or mild burning at the site of application. These effects are usually mild and disappear as the skin adjusts. However, if irritation persists or becomes severe, medical advice is required. The medicine should be applied exactly as prescribed by a physician, typically 5 times daily, starting at the first sign of symptoms (such as tingling or burning).

Avoid Zoster Cream if allergic to Acyclovir (5% w/w) or any of its ingredients. Patients with severe skin reactions, weakened immune system, or chronic skin disorders should inform their doctor before use. Pregnant and breastfeeding women must seek medical advice before starting treatment. The cream is for external use only and should not be applied to the eyes, inside the mouth, or vagina.

How Zoster Cream Works

Zoster Cream contains Acyclovir 5% w/w, which is an antiviral agent. It works by interfering with the viral enzyme DNA polymerase, preventing the herpes virus from multiplying in the infected skin cells. This stops the spread of the infection, reduces symptoms, and helps the skin heal faster.

How to Use Zoster Cream

• Use Zoster Cream exactly as prescribed by your doctor.
• Apply a thin layer of the cream/ointment to the affected area, usually 5 times daily, starting at the first sign of infection.
• Wash your hands before and after applying the medicine.
• Avoid contact with eyes, mouth, or genitals unless directed by a doctor.
• Do not cover the area with tight dressings or bandages.
• Continue using for the full prescribed duration, even if symptoms improve.

Side Effects of Zoster Cream

Common side effects: Mild burning, stinging, redness, dryness, or itching at the site of application.

Serious side effects: Severe allergic reaction (rash, swelling of face/lips/throat, difficulty breathing), unusual skin irritation, or infection at the application site.

Contact your doctor immediately if any severe or persistent side effects occur.
