In this article, I’m going to teach you how to use famciclovir for cold sores. Ninety percent of all people get at least one cold sore in their life. This first occurrence is often the worst (mine sure was!).
After the first infection, many people develop antibodies and never have another cold sore. However, about 40% of American adults have recurring cold sores.
This was me for almost 20 years.
I had so many outbreaks that I suffered from serious psychological issues induced by cold sores.
To make a long story short…
I figured out how to prevent cold sore outbreaks, and I haven’t had a cold sore for four years now. However, millions of people are still suffering, and that’s why I created this blog.
I’ve made it my Life’s Purpose and Mission to help others learn how to prevent and treat cold sores.
So now a lot of my time is spent researching and writing about all of the best cold sore remedies in the world. Today’s topic is the treatment and prevention of cold sores by using a drug called Famciclovir.
Many people are using famciclovir for cold sores, and in this article, I’m going to cover the Pros and Cons and give you a detailed Review of the use of famciclovir for cold sores.
Famciclovir For Cold Sores – Cold Sore Overview
Cold sores, also known as fever blisters, are groups of small blisters that form on or near the lips. Cold sores are a result of something called herpes simplex virus (HSV).
There are two types of HSV, and both can cause cold sores. HSV-1 typically is responsible for cold sores, and HSV-2 is most often the cause of genital herpes.
However, both types of HSV can cause cold sores or genital herpes.
After primary infection, the virus resides in the associated dorsal root ganglion where it lies dormant until an external stimuli (such as stress or immunosuppression) initiate reactivation of the virus from dormancy.
The virus lives on forever, and that’s why people continue to get cold sores over and over again.
Famciclovir For Cold Sores – Famciclovir Overview
Famciclovir is an antiviral drug that is most commonly used to treat infections by the herpes viruses that cause cold sores, genital herpes, and shingles. Famciclovir was approved for medical use in 1994.
Famciclovir is prescribed for the following:
- Herpes zoster (shingles)
- Treatment of herpes simplex virus 2 (genital herpes)
- Herpes labialis (cold sores) in immunocompetent patients
- Suppression of recurring episodes of herpes simplex virus 2. It is also indicated for the treatment of recurrent episodes of herpes simplex in HIV patients.
Since cold sores come from a virus, the powerful antiviral drug Famciclovir is able to fight the herpes simplex virus in a very effective way.
When taken at the first sign of a cold sore (tingle, itch, burn) you can either prevent the cold sore from popping up or at minimum reduce the size and pain and shorten the healing time.
Herpes simplex lives in the nerve endings and thus is never cured, but Famciclovir can be used to treat or even prevent the symptoms of the virus.
Using famciclovir for cold sores can lead to the following benefits:
- Decreases the severity and length of cold sore outbreaks
- Helps the sores heal faster
- Keeps new sores from forming
- Decreases pain/itching
- May also help reduce how long pain remains after the sores heal
In addition, in people with a weakened immune system, famciclovir can decrease the risk of the virus spreading to other parts of the body and causing serious infections.
Famciclovir For Cold Sores – Research
In a study from 2008, famciclovir and other antiviral drugs were tested to see how effective they were in the treatment of cold sores.
Here is a direct quote from the study:
Two treatment regimens with famciclovir (single 1500-mg dose or 750 mg twice daily for 1 day) were studied in 701 patients.30 The patients in the famciclovir groups had a shorter median time until the first lesions healed than did the placebo group (single dose: 4.4 days; 750 mg twice daily: 4.0 days; placebo: 6.2 days). In all of these studies, treatment was initiated when the first prodromal symptoms appeared.”
Furthermore, a 16-page PDF published online by the makers of Famciclovir sited multiple studies and clinical trials showing how using famciclovir for cold sores has significant benefits.
