About Cold Sore Treatment

Cold sores are small, painful blisters that usually appear on or around the lips, mouth, or nose. They’re caused by the herpes simplex virus type 1 (HSV-1) — a highly contagious virus that stays in the body for life and can reactivate during periods of stress, illness, or weakened immunity.

Most people are first exposed to HSV-1 in childhood, and while the virus may lie dormant for months or even years, many people experience repeated flare-ups throughout their lives.

Common cold sore symptoms include:

  • Tingling, burning, or itching around the lips (often the first sign)
  • Clusters of painful blisters or fluid-filled spots
  • Crusting or scabbing over after a few days
  • Swelling, redness, or irritation
  • Sometimes mild fever or sore throat during initial outbreaks

Cold sores are typically self-limiting and heal in 7 to 10 days, but antiviral treatment can speed up healing, reduce symptoms, and lower the risk of spreading the virus.

At EveryDayMeds, we offer prescription antiviral tablets, including:

  • Aciclovir – standard first-line treatment to reduce duration and severity
  • Valaciclovir – a more advanced option with better absorption
  • Valtrex – a branded form of valaciclovir

Antivirals are most effective when taken at the first sign of a cold sore (during the tingling or burning stage). If you experience frequent outbreaks, we may also prescribe suppressive therapy to reduce recurrence.

Following a quick online assessment, your treatment will be reviewed by a UK-registered pharmacist and delivered discreetly to your door — no appointment necessary.

Frequently asked questions

Everything you need to know about this clinic

What causes cold sores?

Cold sores are caused by the herpes simplex virus type 1 (HSV-1), which stays in the body for life. Triggers like stress, illness, sun exposure, or hormonal changes can reactivate the virus, causing outbreaks.

What are the symptoms of a cold sore outbreak?

Cold sores start with tingling or itching, followed by blisters that burst, weep, and scab over. Outbreaks usually last 7–10 days. Starting treatment early can speed up healing.

What treatments are available for cold sores?

We offer antiviral tablets like Aciclovir, Valaciclovir, and Valtrex. These reduce outbreak duration and severity by stopping the virus from multiplying. Frequent outbreaks may need ongoing treatment.

How quickly do cold sore treatments work?

When taken early (at the tingling stage), antivirals can shorten outbreaks by 1–2 days, reduce symptoms, and sometimes stop blisters from forming.

Can I prevent cold sore outbreaks?

Yes—by managing triggers, using SPF lip balm, staying healthy, and considering daily antiviral therapy if you have frequent flare-ups. Avoid close contact during outbreaks.

Is cold sore treatment safe for everyone?

Antivirals are safe for most people but may not suit those with kidney issues, weakened immunity, or during pregnancy. Our online consultation ensures treatment is right for you.
