Aciclovir (topical)

About topical aciclovir

Aciclovir is an antiviral agent. It works by attacking the herpes simplex virus that causes the infection.

Before using topical aciclovir

Before using topical aciclovir make sure your doctor or pharmacist knows:

• If you are pregnant, trying for a baby or breast-feeding.
• If your immune system is not working properly (for instance if you have AIDS).
• If you are taking other medicines, including those available to buy without a prescription, herbal or complementary medicines.
• If you have ever had an allergic reaction to this or any other medicine.

How to apply topical aciclovir

• Before beginning treatment, read the manufacturer's printed information leaflet.
• Use aciclovir exactly as directed by your doctor or pharmacist.
• Wash and dry your hands thoroughly before and after handling aciclovir to prevent spreading any infection.
• Aciclovir cream is usually applied five times a day (use it every four hours but omit the night-time application). Start using it at the first signs of an attack (for instance, tingling, pain, burning or blisters) and continue using it for 5-10 days.
• If you forget a dose, apply it as soon as you remember and then continue using it at the usual times.

Getting the most from your treatment

• Affected areas should be kept as clean and dry as possible.
• Apply aciclovir for a minimum of 5 days, otherwise your infection may come back.
• You should see an improvement in your condition after a few days. If your condition has not got better after ten days, ask your doctor for advice.
• Avoid contact with the eyes. If any of this preparation gets into your eyes, rinse it off with warm water.
• Avoid contact with mucous membranes (inside the nose, inside the mouth, or the vagina).
• If you regularly develop cold sores, or if they develop in your mouth, speak to your doctor as other preparations may be more suitable for you to use.
• If you buy any medicines, check with a pharmacist that they are safe to take with your other medicines.
