Penciclovir Cream Dosage
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.
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.
Continue to use penciclovir even if you feel well. Do not stop using penciclovir without talking to your doctor.
Other
Keep all appointments with your doctor. Penciclovir should only be used on the lips and face. Avoid getting it in your eyes. Keep the infected area clean and dry.
Do not let anyone else use your medication. Ask your pharmacist any questions you have about refilling your prescription. If you still have symptoms of infection after you finish the penciclovir, call your doctor.
It is important for you to keep a written list of all of the prescription and nonprescription (over-the-counter) medicines you are taking, as well as any products such as vitamins, minerals, or other dietary supplements. You should bring this list with you each time you visit a doctor or if you are admitted to a hospital. It is also important information to carry with you in case of emergencies.
