About
About cold sores
Cold Sores are blisters around the mouth caused by the herpes simplex virus (HSV-1). They are contagious and can be triggered by stress, illness, or sun exposure. They are common but usually clear up on their own within 10 to 14 days, but the best cold sore treatment can ease discomfort and speed up recovery considerably.
SwiftDoctor offers prescription cold sore medication, including aciclovir tablets for cold sores and aciclovir cream, so you can access cold sore treatment quickly, before or as soon as a flare-up starts. Cold sore tablets work throughout the body to fight the virus, while cream is applied directly to the affected area.
For the best treatment for cold sores and fever blisters, timing matters. Starting antiviral treatment as soon as you notice the early tingling or itching sensation gives the best chance of reducing how long the cold sore lasts.

FAQs
Frequently asked questions
The best cold sore treatment is usually an antiviral medication such as Aciclovir, available as tablets or cream, started as early as possible and ideally at the first tingling sensation before a blister appears. Aciclovir tablets for cold sores work systemically, while the cream targets the affected area directly.
There is no real difference between a cold sore and a fever blister. The terms are commonly used interchangeably to describe small, fluid-filled blisters that usually appear on or around the lips and are caused by the herpes simplex virus (HSV-1). They may begin with tingling or burning before blisters develop and are contagious while they are healing.
Yes. Aciclovir tablets are a well-established cold sore treatment that works by stopping the herpes simplex virus from multiplying, helping to shorten the duration of an outbreak and ease symptoms when started promptly.
Cold sore tablets work throughout the body to fight the virus internally, which can be more effective for frequent or severe outbreaks, while cream is applied directly to the cold sore to target the local area. Some people use both together for more effective relief and your SwiftDoctor clinician can advise on the best combination for you.
When started early, at the first tingling or itching sensation, cold sore medication can help reduce how long an outbreak lasts and ease discomfort within a day or two. Starting treatment after the blister has already formed is still worthwhile but tends to be less effective than early treatment.
Common triggers include stress, illness, sun exposure, and a weakened immune system, so managing these where possible can help reduce recurrence. If you get frequent cold sores, a SwiftDoctor clinician can advise on preventative options and keeping cold sore treatment on hand for the earliest signs of a flare-up.
