Treat Cold Sores

Order a prescription to treat cold sores

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.

Order a prescription for treatment online - our service is fast and convenient. To place your order, fill in our brief medical questionnaire. Our doctor will review your order and approve a prescription for an appropriate treatment.

You can use your prescription to buy your medication at any pharmacy in Ireland.

  • Order and pay for your prescription. 
  • A Superdrug Online Doctor will approve a prescription for an appropriate treatment
  • Orders received before 4pm will be processed the same day. Orders received after 4pm will be processed the next working day.
  • Once your prescription has been dispatched, you will receive it within 3-5 working days.

Common side effects from Aciclovir can include:

  • Headaches

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.
