Effective Antiviral Treatment for Cold Sores (HSV-1)
Aciclovir is a prescription antiviral medication used to treat cold sores, caused by the herpes simplex virus (HSV-1). It helps to shorten outbreaks, reduce discomfort, and speed up healing when taken at the first sign of symptoms such as tingling, itching, or burning.

How Does Aciclovir Work?
Aciclovir works by interfering with the herpes virus’s ability to replicate. While it doesn’t cure the virus, it can:
- Shorten the duration of cold sore outbreaks
- Speed up healing of blisters and lesions
- Reduce severity of symptoms
- Help prevent the virus from spreading
It’s most effective when taken as soon as symptoms appear.
- Treats cold sore outbreaks quickly and effectively
- Shortens healing time when taken early
- Reduces pain, itching, and inflammation
- Can be used for suppressive treatment if outbreaks are frequent

Who Can Use Aciclovir?
- Experience cold sores caused by HSV-1
- Want to reduce the duration and severity of an outbreak
- Experience frequent or severe outbreaks
- People with kidney conditions (may require dose adjustment)
- Those allergic to aciclovir or similar antivirals
- Pregnant or breastfeeding individuals (consult a prescriber first)
How to Use Aciclovir for Cold Sores
- Take 200mg five times daily for 5 days
- Start as soon as symptoms like tingling or itching begin
Swallow tablets whole with water. It’s important to complete the full course, even if symptoms begin to improve.
