The major drugs developed to work against herpes simplex vurus (HSV) are antiviral agents called nucleosides and nucleotide analogues, which block viral reproduction. Valtrex (valacyclovir) was the second antiviral medication to come to market in the United States, and it was approved by the FDA in December 15, 1995. Antiviral agents reduce viral replication by inhibiting viral DNA synthesis, needed to reproduce itself. Clinical studies have not found any significant differences in effectiveness among the three medications.
For the treatment of first genital herpes infections, oral acyclovir or valacyclovir is preferable to famciclovir. For the treatment of recurrent infections, clinical trials have demonstrated that acyclovir, valacyclovir, and famciclovir have equivalent efficacy. Intravenous acyclovir is used to treat serious flare-ups or outbreaks that effect internal organs. When used as an episodic treatment, valacyclovir can help the sores heal faster, shorten the period of pain during the outbreak and cut down the time during which the virus is detected on genital skin surfaces (virus shedding).
Generic acyclovir is usually less expensive than the other two drugs and therefore preferable. Based on 224 user reviews.Eliminate pain a fever blisters can naturally you break open sores. There are no data on the effectiveness of treatment with Valtrex when initiated more than 72 hours after the onset of signs and symptoms. There are no data on the effectiveness of treatment with Valtrex when initiated more than 24 hours after the onset of signs or symptoms. In patients with a history of 9 or fewer recurrences per year, an alternative dose is 500 mg once daily.
Patients should be counseled to use safer sex practices in combination with suppressive therapy with Valtrex. Initiate therapy at the first sign or symptom if medical management of a genital herpes recurrence is indicated. The safety and efficacy of Famvir therapy beyond 1 year of treatment have not been established. The efficacy of famciclovir for initial episode genital herpes infection has not been established.
Possible side effects from oral agents include nausea, vomiting, headache, fatigue, tremor, and very rarely, seizures.
Acyclovir speeds healing of lesions and suppress viral shedding if taken within 24 hours of the first indication of a recurrent episode. Valacyclovir provides a unique mechanism of enhancing the oral bioavailability of the parent compound, acyclovir. When taken as soon as the first signs of an outbreak are noticed, such as tingling, itching or redness, valacyclovir may be able to completely prevent the development of painful blisters. Famciclovir is converted into its active compound within the infected cell by contact with an enzyme from the virus. If the costs of the drugs are equivalent, however, the choice is between the safety record of acyclovir and having to take fewer daily doses of valacyclovir or famciclovir.

Valtrex is a prodrug of acyclovir, meaning that the body converts it to acyclovir after it has been absorbed. Like valacyclovir, it is well absorbed, persists for a longer time in the body, and can be taken less frequently than acyclovir.
The efficacy of reducing transmission beyond 8 months in discordant couples has not been established. The efficacy of Famvir has not been established when treatment is initiated more than 6 hours after onset of symptoms or lesions. They can effect the kidney, however, and people with kidney problems should use them with caution and at lower doses. This medication delivers acyclovir more efficiently so that the body absorbs much of the drug, which has the advantage of taking the medication fewer times during the day.
Intravenous administration increases the risk for kidney problems and can cause blood clots at the injection site. It has better bioavailability (about 55%) and has a longer duration of action than acyclovir. It remains active in the body longer than acyclovir (half the dose is still active after 10 to 20 hours) and, like valacyclovir, requires less frequent dosing (usually two or three times a day). The antiviral medications available in pill form acyclovir, valacyclovir, famciclovir have been specifically developed for the treatment of genital herpes. The main advantage of valacyclovir is higher concentration of acyclovir in the bloodstream without added toxicity.
Antiviral medications may significantly lessen the severity of a primary outbreak and reduce the time it takes genital herpes outbreaks to heal. It is available in a one-day regimen for oral herpes, a once-daily dose to suppress genital herpes, and a three-day treatment for recurrent herpes.
The medication also decreases the number of days of painful symptoms and for some people, the number of days you can spread the virus. Antiviral medication is most effective if it is taken when you first notice the prodromal symptoms tingling and pain of a recurrent genital herpes outbreak and if they are taken for the next 5 to 7 days or until symptoms go away. Some people with frequent recurrent outbreaks take antiviral medication every day suppressive therapy to help reduce the frequency and duration of recurrent outbreaks.
