Book onlineAbout cold sores
Cold sores are small, painful blisters around the mouth caused by the herpes simplex virus, which stays dormant in the body between outbreaks and can be triggered by illness, stress, sun exposure, or tiredness.
Antiviral cream or tablets work best started at the very first tingling sensation, before the blister appears — for people who get frequent outbreaks, a GP can also discuss preventive treatment.
Online review suits recurring cold sores in someone who recognises their own pattern. A first-ever outbreak, or sores that are unusually severe, widespread, or not healing, are better assessed in person.
Frequently asked questions
When should I start treatment?
As early as possible — ideally at the first tingling or itching sensation, before the blister fully forms.
Can you prescribe something to prevent outbreaks, not just treat them?
For frequent recurrences, your GP can discuss preventive (suppressive) treatment options with you.
Is this the same as a canker sore (mouth ulcer)?
No — cold sores are viral blisters on the outer lip/skin; mouth ulcers are inside the mouth and have different causes.
Are cold sores contagious?
Yes, especially when a blister is present — avoid close contact and sharing items like cups or lip products during an outbreak.
