What is Denavir?
Denavir acts as an antiviral medicine. Denavir is a prescription-only cream that treats sores that
appear on the lips and result from the Herpes simplex virus. The medicine is intended for both children and adults who are 12 or older. Denavir isn't a treatment for cold sores. You might continue to suffer from cold sores in the near future.
Warnings
Avoid applying the cream to the inner part of the nose or inside or around the eyes.
Before taking this medicine
You shouldn't use the Denavir cream if you are sensitive to penciclovir. Because penciclovir topical (for the face) doesn't get absorbed by the body, taking this drug isn't expected to cause harm when you are pregnant or nursing. Denavir cream is not authorized to be used by anyone less than 12 years old.
How to take Denavir cream?
Utilize Denavir precisely as prescribed by your physician. Follow the directions on the prescription label. Do not take this medicine in smaller or larger amounts or for longer than prescribed.
Do not consume by mouth. Topical medicine should be used only on the face and lips. If this medication gets into your mouth or nose, wash it off by drinking water. Denavir is recommended for treating cold sores that are on your face and lips only. To get the best results, begin taking penciclovir as quickly as possible following the onset of signs of a cold-like sore (tingling or itching, redness, and a lump).
Cleanse your hands prior to and immediately after using Denavir cream. Also, wash and dry the area of your skin being treated. Spread a light layer of penciclovir on the sore. Make sure to cover just the cold sore, the skin area that you feel tingling, or signs of a cold sore that is developing. Apply the cream slowly until the medication disappears. Don't apply Denavir cream to an area inside your nose or near your eyes.
Denavir cream is typically applied every two hours during the day for four days in succession. Follow the instructions of your doctor for dosing extremely carefully. Contact your physician if your symptoms don't improve or if they become worse. Keep it at room temperature, free of heat and moisture.
