What causes cold sores?
Cold sores are caused by the herpes simplex virus type 1 (HSV-1). Once infected, the virus remains dormant in the body and can be triggered by stress, illness, sunlight, or a weakened immune system.
-
What treatments are available for cold sores?
Antiviral creams such as aciclovir can reduce healing time when applied early. Oral antiviral tablets such as valaciclovir are often more effective for frequent or severe outbreaks.
-
When should I start treating a cold sore?
Treatment is most effective when started at the first sign of a cold sore — often a tingling or itching sensation before a blister appears. Starting treatment early can significantly reduce the outbreak duration.
-
Can cold sores be prevented?
Antiviral tablets can be taken as suppressive therapy to reduce the frequency of outbreaks in people who get cold sores regularly. Avoiding known triggers can also help.
-
Are cold sore treatments safe?
Yes. Antiviral treatments for cold sores are well-tolerated and widely used. Your pharmacist will confirm suitability during your assessment.
