Cold sores can be embarrassing, uncomfortable, and unpredictable. If you get cold sores, you’re not alone. Between 20% and 40% of Americans suffer from recurrent cold sores.11.

Cold sore outbreaks often begin with tingling, itching, and/or burning sensations before any visible signs appear.2,32. Arduino PG, Porter SR.

There is currently no cure for cold sores or the virus that causes them.33. Fatahzadeh M, Schwartz RA. Herpes simplex virus infections: epidemiology, pathogenesis, symptomatology, diagnosis, and management. J Am Acad Dermatol. 2007;57:737-763. But for adults and children 12 or older who have recurrent cold sores, Denavir® (penciclovir cream, 1%) can help them heal when they do reappear.44.

Denavir should only be used on herpes labialis on the lips or face. Application to mucous membranes is not recommended. Denavir should not be used in patients with known hypersensitivity to the product or any of its ingredients.
There are no adequate and well-controlled Denavir studies in pregnant women; therefore, Denavir should be used during pregnancy only if clearly needed. There is no information on whether Denavir is excreted in human milk after topical administration; a decision whether to discontinue Denavir should take into account the importance of the drug to the mother. The effect of Denavir has not been established in immunocompromised patients. Denavir does not cure cold sores.
In clinical studies, the most common adverse reaction with Denavir was headache, which occurred in 5.3% of patients who received Denavir and 5.8% of patients who received placebo. Other adverse reactions with Denavir occurred in less than 2% of patients and included application site reaction, decreased sensitivity to touch/local anesthesia, taste perversion, and rash.
Other reported adverse reactions have included swelling of the mouth or throat, pain, alterations in sense of smell, abnormal touch sensation, itching, skin discoloration, and hives.
Denavir is available by prescription only. Please see the Full Prescribing Information.
