Several drugs, including Valtrex, are available to treat cold sores. Some are used topically (on the skin) and others are used orally (by mouth), but the goal is to take care of cold sores as early as possible.
That is because beginning a medication if prodromal symptoms such as tingling, tingling, or inflammation start will give a individual with a cold sore the very best possibility of preventing an actual blister from multiplying or forming a blister’s path when it does look.
A Word FDA Approval
A number of antiviral medications are used in the treatment of herpes infections, which cause cold sores, also called fever blisters.
Though the FDA has approved the use of certain drugs for cold sores, some antiviral drugs are not especially FDA-approved for cold sores but have been shown in clinical trials to be effective treatments. Given this, getting a prescription for an off-label utilization of one of these drugs may help remove or protect against cold sores.
The choice to use a medication that is prescribed off-label ought to be made based on current scientific information and discussed thoroughly with your healthcare provider.
Cold Sore Treatment Gains
Antiviral drugs may have several results on oral herpes simplex viral infections, such as cold sores. These medications can decrease the time it takes for cold sores to heal and reduce symptoms, especially pain. And when taken soon enough, they can prevent lesions from happening, reduce the quantity and size of lesions which develop, as well as reduce the amount of viral shedding (the stage at which the virus is contagious).
The First Outbreak
The first epidemic of any herpes simplex infection is usually worse than recurrent infections. A first outbreak of oral herpes ought to be treated with oral medications, while recurrences can be treated with oral or topical drugs.
The first episode (which normally occurs in childhood) is also treated more, normally for seven to ten days using an antiviral medication.
Recurrent infections, on the other hand, are treated for a shorter time period.
Topical Denavir for Cold Sores
Denavir (Penciclovir 1% lotion ) is FDA-approved for recurrent cold sores. Beginning treatment within one hour of an outbreak can reduce recovery time by two days, as well as reduce symptoms. Denavir can also reduce the duration of viral shedding.
In general, the earlier Denavir is launched, the greater the benefits. That being said, improvement is often still possible when therapy is started after vesicles (the cold sores) develop.
Why Acyclovir Helps
Zovirax (Acyclovir 5% lotion ) can also be FDA-approved for the treatment of recurrent cold sores. In studies, regular application of the lotion reduced healing time by roughly 12 hours.
Oral acyclovir given five times a day for primary gingivostomatitis in children can substantially lessen the length of fever, eating issues, and drinking difficulties, as well as viral shedding. Employing low-dose oral acyclovir for cold sores can shorten the duration of symptoms, but higher doses may be required to decrease pain.
The Effect of Famciclovir
Famvir (Famciclovir) is approved by the FDA for treating cold sores. If started in the first sign of symptoms, carrying one high dose of Famvir can shorten the herpes disease by two days.
Valtrex for Cold Sores
Valtrex (Valacyclovir) can be approved by the FDA to treat cold sores and it’s a well-known, favorite treatment. If started at the very first indication of symptoms, taking Valtrex two times every day for a single day can shorten the duration of a herpes infection.
Suppressive therapy, which means taking medicine daily to prevent cold sore outbreaks, is not yet FDA-approved. That being said, studies have revealed that individuals who’ve six recurrences or more annually may benefit from taking daily doses of acyclovir or Valtrex to decrease the amount of recurrences and reduce viral shedding.
