Based on the recent demise of experimental vaccines from Genocea and Vical the prospects for a therapeutic vaccine for genital herpes look mighty bleak at this time. So, for most patients who need treatment valacyclovir (Valtrex) is the only choice (1,2). It works well for most people, but not for everyone. VACCINES FOR TREATMENT OF INFECTIOUS DISEASES There has never been a therapeutic vaccine for any infectious disease, and there isn't one on the horizon. But there are plenty of drugs that work quite well for infections - antibiotics, antifungals, and antivirals. Since herpes is a viral infection is it not unrealistic to predict that an antiviral drug that works better than Valtrex could be discovered. Based on the stunning success of antiviral drugs for treating HIV (3) and hepatitis C (4), most of them coming out of the pharmaceutical industry, it is reasonable to think that this is not only possible but maybe even likely that alternative drugs could be discovered. There is an alternative to Valtrex in Phase II trials right now. The drug is called pritelivir, and it is looking quite good in clinical trials. SOME DRUGS INHIBIT SYNTHESIS OF VIRAL DNA AND STOP REPLICATION Valtrex/acyclovir (5) work because they inhibit an enzyme called herpesvirus DNA polymerase, which is responsible for the assembly of new viral DNA, a necessary step in the virus's replication. DNA consists of a very long chain of covalently bound deoxyribose (a sugar, orange circle) units. buy erythromycin in uk Valacyclovir given in a 5-day regimen of 500 mg twice per day is effective as short-term treatment of episodes of recurrent genital herpes. This study compared the efficacy of a shorter, 3-day course (for 402 patients) with that of a 5-day course (for 398 patients) of valacyclovir for persons with frequent recurrence of symptoms. No significant differences were detected between the 2 dosing schedules for any of the end points measured. Median times to lesion healing, of pain duration, and of episode length for the 5-day versus 3-day treatment were 4.7 versus 4.4 days, 2.5 days versus 2.9 days, and 4.4 days versus 4.3 days, respectively. The proportions of patients with aborted lesions were 26.6% and 25.4% in the 5-day and 3-day groups, respectively. A 3-day course of 500 mg of valacyclovir administered twice daily as episodic treatment of recurrent genital herpes is equivalent to a 5-day course with regard to key markers of efficacy.

Valacyclovir (generic for Valtrex) is a medication approved by the FDA to treat different types of herpes infections including HSV-1 and HSV-2. It is also used to treat shingles (herpes zoster), which is caused by the Varicella Zoster Virus (VZV). There are four different ways that herpes medications can be used to treat genital herpes (HSV-1 and HSV-2): 1. To Treat Or Abort An Outbreak When There Are Early Symptoms (Prodrome): For both genital and oral herpes, people can take medication when their specific prodrome tells them an outbreak is about to occur. The medication will stop an outbreak cold (often) and when it does not, it can shorten the outbreak and make it milder than it might have been otherwise. To Prevent Outbreaks When There Are No Symptoms But Outbreaks Are More Likely: Patients also learn the life circumstances or behaviors that lead to more outbreaks. For some, a lack of sleep, increased alcohol, another illness, stress, too much sunlight, irritation, or anything that can affect one’s immunity can spur an outbreak. That means that some patients can know not just when they feel an outbreak coming on but can know when they are more likely to have an outbreak due to their circumstances. They might be under stress, having more sex therefore causing more physical irritation, drinking a bit more than they should, or missing sleep over an extended period. Valacyclovir belongs to the class of medications known as antivirals. It is used to treat a viral infection affecting the skin known as shingles (herpes zoster). It is also used to treat cold sores, and to treat and prevent recurrences of genital herpes. It works by interfering with the way the virus reproduces. Valacyclovir works by stopping the virus from multiplying and spreading to nearby healthy cells. 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.
