Cold sore treatment and prevention

Cold sores are caused by a form of the Herpes Simplex Virus (HSV) and may develop when an individual has a cold or fever. They can also can be triggered by sun exposure, emotional distress and health troubles.

If you’re suffering from a cold sore try Blistex Antiviral to help relieve the symptoms. Blistex Antiviral contains Aciclovir which stops the virus from replicating and reduces the severity of an outbreak.
