Cold Sore Treatment

Order aciclovir to treat oral herpes

Cold sores are caused by the herpes simplex virus and they can be treated with antiviral medication.

Aciclovir tablets help heal the sores faster and are particularly effective when taken as soon as the first symptoms appear.

Aciclovir is also prescribed as a suppression treatment for people who encounter frequently recurring bouts of oral herpes.

Cold sore healing can also be improved with hydrocolloid dressings (Compeed invisible cold sore patches) available in most pharmacies. Local anaesthetic creams applied to the blisters and oral painkillers such as paracetamol can ease any discomfort of the blisters.

Without treatment, cold sores usually heal within 7 - 10 days.

If you want to discuss your cold sores with a doctor, you can book a telephone consultation. Our doctors will be able to offer personalised advice.
