Cold sores are small blisters that develop on the lips or around the mouth. They're caused by the herpes simplex virus (HSV). Cold sores should heal within 10 days, but are contagious and may be irritating or painful while they heal.
Although there is no cure, the symptoms can be effectively controlled using antiviral medications.
Pharmica offer 2 variations of antiviral medication: Aciclovir and Valaciclovir. Aciclovir is more cost effective, but has to be taken more frequently than Valaciclovir.
