Valacyclovir for Episodic Treatment of Genital Herpes: A Shorter 3-Day Treatment Course Compared with 5-Day Treatment. No significant differences were detected between the 2 dosing schedules for any of the end points measured. If a 3-day course of treatment is equivalent in efficacy to the 5-day course, then the reduced therapy duration could increase convenience to patients who prefer discreet, episodic medication regimens and could reduce the cost of treatment. Two types of HSV can cause genital herpes: HSV-1 and HSV-2. Treatment with valacyclovir 500 mg daily decreases the rate of HSV-2 transmission in discordant, heterosexual couples in which the source partner has a history of genital HSV-2 infection (349). Valacyclovir 500 mg once a day might be less effective than other valacyclovir or acyclovir dosing regimens in persons who have very frequent recurrences (i. Likewise, herpes labialis and herpes zoster can be both physically and psychologically painful. While there is no cure for these conditions, treatment to alleviate symptoms, suppress recurrences and reduce transmission has been drastically improved over the past 20 years with the use of guanine nucleoside antivirals, such as valacyclovir hydrochloride (Valtrex), GlaxoSmithKline) the highly bioavailable prodrug of acyclovir (Zovirax((R)), GlaxoSmithKline), and famciclovir (Famvir, Novartis), a highly bioavailable prodrug of penciclovir (Denavir, Novartis). Valacyclovir is the only antiviral drug approved for a once-daily dose of suppressive therapy for genital herpes, as well as the only antiviral drug US FDA approved for a 3-day regimen of episodic treatment of recurrent genital herpes.
Episodic treatment of recurrent genital herpes is of questionable benefit, but it may be helpful in appropriately selected patients. Patients who have six or more recurrences of genital herpes per year can be treated with one of the following regimens: acyclovir, 400 mg twice daily; valacyclovir, 1 g daily; or famciclovir, 250 mg twice daily. Long-term suppressive therapy can significantly reduce these recurrences and is safe to use indefinitely. For women with recurrent genital herpes, the suggested dose of acyclovir is 400 mg, three times daily, starting around the 36th week of pregnancy. It does not cure shingles, cold sores, or genital herpes, but it does help the sores to heal more quickly, and it relieves pain and discomfort. When used to prevent recurrences of herpes, it also reduces the risk of transmission (spreading) of the infection to others.
These medications differ in their chemical structure, dosage, and price. Antiviral medication can reduce the number of outbreaks by 70 to 80. For the treatment of first genital herpes infections, oral acyclovir or valacyclovir is preferable to famciclovir. Learn about patient information and medication guide for the drug Valtrex (Valacyclovir Hydrochloride). VALTREX does not cure herpes infections (cold sores, chickenpox, shingles, or genital herpes). Your dose of VALTREX and length of treatment will depend on the type of herpes infection that you have and any other medical problems that you have. Other less common side effects in adults include painful periods in women, joint pain, depression, low blood cell counts, and changes in tests that measure how well the liver and kidneys work. Valacyclovir is used to treat genital herpes, cold sores, shingles, and chicken pox. Valacyclovir can be harmful to the kidneys, and these effects are increased when it is used together with other medicines that can harm the kidneys.
Treatment Of Common Cutaneous Herpes Simplex Virus Infections
You can spread genital herpes to others, even when you have no symptoms. The primary episode of genital HSV infection can be associated with a multitude of constitutional symptoms and signs, such as fever, malaise, and headache. Over time, recurrences due to either viral type generally decrease in number and severity, although there is substantial variability in the clinical course from patient to patient 3,4. A large-scale, placebo-controlled, dose-ranging trial of peroral valaciclovir for episodic treatment of recurrent herpes genitalis. In this treatment method, the patient will take a daily dosage of acyclovir or valacyclovir either once or twice daily. 2- Treatment for genital herpes (preventing it, treating the initial outbreaks of it and treatment of herpes episodes.

Comparison Of Herpes Antiviral Drugs
Then, an evidence-based dosing regimen must be selected. Genital herpes can result from infection with either HSV type 2 or type 1, mainly HSV type 2 in this country, which typically causes more recurrent and severe manifestations of disease. Famciclovir, the oral prodrug of penciclovir, offers increased bioavailability as well as a substantially longer half-life compared with acyclovir. Intermittent episodic therapy with topical acyclovir and penciclovir creams have been shown to decrease lesion healing time and symptomseverity in recurrent labial herpes. High-dose IV acyclovir is the drug of choice for herpes simplex virus encephalitis. Genital herpes is an infection of the genitals (penis in men, vulva and vagina in women) and surrounding area of skin. Antiviral medicines such as aciclovir, famciclovir, and valaciclovir are used to treat genital herpes infection. Many people who are infected with this virus never have symptoms but can still pass on the infection to others. This is usually much reduced if you start an antiviral medicine within five days of the onset of symptoms. It is used to treat infections caused by two common viruses – herpes zoster and herpes simplex. You will have been prescribed valaciclovir to treat (or prevent further episodes of) one of these infections. Valaciclovir works by preventing viruses from multiplying, and this reduces the severity of the infection and stops it from spreading.
Herpes Simplex Virus answers are found in the Johns Hopkins Antibiotic (ABX) Guide powered by Unbound Medicine. HSV suppressive therapy does NOT decrease risk of HIV acquisition among HSV-infected, HIV-uninfected woman. Valtrex is indicated for the treatment of herpes zoster (shingles) and ophthalmic zoster in immunocompetent adults (see sections 4. Valtrex can prevent lesion development when taken at the first signs and symptoms of an HSV recurrence. The dose of Valtrex should be reduced in patients with impaired renal function as shown in Table 1 below.
