Denavir is a medicated antiviral cream, one of the major brand names of the drug penciclovir. It is prescribed to heal cold sores brought on by herpes. These cold sores can appear anywhere on the face but are especially prevalent on the lips. Denavir isn’t a cure for the herpes simplex virus, but it will help to clear up the cold sores and the itching and pain that can accompany them. The sooner you apply Denavir after you first notice your symptoms, the more effective it will be.
In general, you use it for four days straight, and you will apply it often: every two hours for as long as you are awake. However, individual prescriptions may come with different instructions, so be sure to follow these instructions carefully. And keep using this cream until your prescription runs out, even if your cold sores have gone away before that time. If you don’t keep using this medicine for as long as you’re supposed to, the cold sores could reappear.
When it’s time to apply Denavir to your face, you’ll want to wash and dry your hands, and also wash and dry the part of your face where the cream will go. Use enough cream to cover every sore that you have entirely, and then rub the cream in thoroughly using soft, gentle motions. Be careful not to apply this cream too near your eyes, however, as it’s easy for it to run into the eyes and cause burning and irritation. You should also take care not to get any Denavir inside your nose. Also, Denavir is only meant to be used on cold sores afflicting the face or lips, and not for any other parts of the body. If you feel unsure about how to use apply this medication, your doctor, a nurse or your pharmacist could explain the procedure to you in greater detail, and perhaps even provide a demonstration.
Denavir has been classified by the U.S. Food and Drug Administration as a category B drug, which means it’s generally safe for pregnant women to use and is not likely to cause any harm to a fetus. However, this medication may not be safe for women who are breastfeeding as some of it may be able to pass through breast milk. In any event, if you are pregnant or breastfeeding, you’ll want to let your doctor know before he or she prescribes this medicine for you. This medication is also unsafe for anyone who is allergic to penciclovir or acyclovir. (If you know you’re allergic to the drug Zovorax, then you’ll probably be allergic to Denavir as well.)
Because Denavir is such a mild drug, you won’t have to follow any special dietary restrictions when you are using it. In other words, you can eat or drink or do whatever you’d like (unless, of course, your doctor gives you specific instructions otherwise). And you’re also unlikely to overdose on this medication. However, if for some reason you feel you’ve come into contact with too large a quantity of this cream, or if you or anyone in your household has accidentally swallowed any of this cream, you should call the poison control center or go right away to the emergency room.
Just because it is mild, however, doesn’t mean that Denavir won’t cause you any side effects. Some of its known side effects are skin irritation in the areas where it is applied and headaches. Unless these side effects are especially severe for you, you don’t have to be concerned about them and you don’t have to seek medical help for them.
