Denavir
Denavir is used on the lips and faces of adults to treat cold sores caused by herpes simplex virus. Penciclovir does not cure herpes infections but decreases pain and itching if applied when the earliest symptoms first appear.
How Taken
Clean and dry the area before applying the cream to avoid spreading the infection. Rub the cream in gently, using enough cream to cover all sores completely. Penciclovir comes as a cream. It is usually used externally every 2 hours while you are awake for 4 days. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist or doctor to explain any part you do not understand. Use penciclovir exactly as directed. Do not use more or less of it or use it more often than prescribed by your doctor. Use this medication as soon as possible after symptoms appear. Continue to use penciclovir even if you feel well. Do not stop using penciclovir without talking to your doctor.
Warnings/Precautions
Tell your doctor if you are pregnant, plan to become pregnant, or are breast-feeding. If you become pregnant while taking penciclovir, call your doctor.
Tell your doctor and pharmacist if you are allergic to penciclovir, acyclovir (Zovirax), or any other drugs.
Tell your doctor and pharmacist what prescription and nonprescription medications you are taking, including vitamins.
Missed Dose
Apply the missed dose as soon as you remember it and apply any remaining doses for that day at evenly spaced intervals. However, if it is almost time for the next dose, skip the missed dose and continue your regular dosing schedule. Do not apply a double dose to make up for a missed one.
Possible Side Effects
Some common side effects reported with Denavir include:
- headache
- irritation at the site of application
