Cold Sore - Medication Options

The most common cold sore medications in use to help people treat a cold sore are Famvir (famciclovir), Valtrex (valacyclovir) and Zovirax (acyclovir). These cold sore drugs are in a pill form. Other cold sore medications, including acyclovir and penciclovir (Denvair), are available in a topical form.

Cold Sore Treatment - Famvir vs Valtrex vs Zovirax

Famvir, Valtrex and Zovirax are all used to treat cold sores. These medications are antiviral medications that can help shorten the length of cold sore symptoms, especially if used early in a cold sore outbreak. These antiviral cold sore treatments can also reduce the likelihood of getting a cold sore in the future. Understanding the differences may help one get the appropriate cold sore prescription with the guidance of one’s medical provider.

Famciclovir, marketed as Famvir, is a type of antiviral drug known as a guanosine analogue. Famciclovir is available as a generic treatment for herpes and is indicated for the treatment of herpes zoster. Famciclovir, like some other cold sore treatments, is generally more effective if used early when cold sore symptoms present themselves. Valacyclovir is marketed under the names Valtrex and Zelitrex. Valacyclovir is FDA approved for the treatment of cold sores and other herpes infections like genital herpes. In healthy people, resistance to valacyclovir is not widespread. Zovirax consists of acyclovir, an antiviral medication used in the treatment of herpes simplex virus infections. Acyclovir is a nucleic acid analogue medication that helps reduce the amount of genetic material the virus can produce. Acyclovir is safe for many people and is also an affordable cold sore treatment. Acyclovir tends to be effective in people with normal immune systems.

Some antiviral medications are also available in a form that can be applied topically. In particular, acyclovir and penciclovir (Denvair) are sometimes prescribed for this purpose. Penciclovir is considered a nucleoside analogue antiviral drug and is often prescribed as a 1% cream. Penciclovir can help reduce the length of cold sore symptoms.

When consider acyclovir versus penciclovir for topical cold sore treatment, some research suggests that penciclovir might be slightly more effective. However, penciclovir is usually much more expensive than topical acyclovir.

Cold Sore - Medication Effectiveness

Cold sore medications like Famvir, Valtrex, Zovirax and Denvair can help people treat a herpes infection but they do not work for everyone. And, even if one has a cold sore infection resolve while taking a cold sore medication, cold sores can return at a later date, even if the medication is used properly.

Cold Sore Prescription Medications - Side Effects

Like most medications, antiviral medications for cold sores are not without side effects. When used for cold sore treatment, cold sore medications, pills and creams can cause an upset stomach with vomiting and diarrhea and a headache. Some people can experience worse symptoms affecting the nervous system, kidneys, joints and blood cells. All cold sore medications can also cause serious side effects such as an allergic reaction in susceptible people. Many side effects will go away once the cold sore medication treatment is stopped. It is strongly recommended that one consult with one’s medical provider and pharmacist before starting a new cold sore treatment.

Cold Sore Medications - Online

Because many cold sore medications are prescription medications, one cannot simply buy Valtrex, Famvir, Zovirax or Denvair online. The reality is that prescription cold sore medications need to be dispensed by a licensed pharmacy online or at a retail pharmacy location after an appropriate prescription is written by a medical provider. Through Push Health, you will be connected with a licensed doctor or medical provider in your state who can prescribe cold sore medications for you to help you treat your herpes infection if it is safe to do so.
