Pharmacological effect
The drug is absorbed in the gastrointestinal tract and under the influence of liver enzymes is converted into acyclovir and valine. Then, acyclovir is embedded in the structure of the viral DNA, which disrupts the synthesis of DNA polymerase viruses and causes the microorganism to lose its ability to reproduce. If the saved human immunity is normal, the desired therapeutic result from drug treatment will be achieved with greater probability.
With compromised immunity, the sensitivity of the virus to the active substance is reduced. This is due to the ability of the virus to change the structure of DNA depending on the state of the human immune system. Excretion from the body occurs in the urine. The elimination half-life is 3 hours. If the patient suffers from kidney failure, the half-life period is extended to 14 hours. Taking Valtrex helps to cope with the pain syndrome, reducing the duration of pain and its acuity.

Reviews
We picked up some feedback from people about Valtrex:
- Alina. A very high-quality tool, both for treatment and for the prevention of herpes. He helped me a lot, earlier relapses of infection showed up almost every month, but after a course of treatment for a year now, as there are no characteristic rashes on the lips. Of course, the drug is expensive, but it's worth it. Before that I tried to be treated cheaply, but the effect was short-lived. So I do not advise you to save on your health.
- Ksenia. My son found shingles, doctors said that they need systemic therapy, otherwise there will be complications. They wanted to write out Waltrex, but I read negative comments on him. I had to persuade the doctors to write a safe analog of Valtrex. Let the treatment last longer, but I do not want my son to "plant" the liver with a dangerous medicine.
- Gulnara. I was assigned to him before childbirth. Before that, I was treated for genital herpes and several times a year there were exacerbations. The drug is a saw with the purpose of prevention, so that the child after childbirth had no problems, and he was not affected by the herpes virus. As a result, everything went well, the child was healthy and had no evidence of infection in him. Now he is no longer breastfeeding and now I can take Valtrex for preventive purposes, so that there will be no relapse of the disease.
- Julia. I have been fighting herpes for a very long time. The rash appeared more than five times a year. At first I used only ointment, eventually started to try more and pills. They, of course, help better, because to treat the virus from the inside is much more effective. The doctor recommended me Valtrex. Such an expensive tool did not want to buy, but I was assured that it would definitely help. And really helped, the herpes did not bother me for about a year. It was the best drug I've ever tried. Although in truth, for this money, I wanted more effect. I would like to find a cheaper analog. "Valtrex" is an excellent remedy for herpes, its only negative is the price.
- Masha. Ehh, good tablets, the last 5 years, only they escaped with exacerbations (with herpes hand in hand with the diaper), a little felt itching on the lips - immediately started taking, if you have time to take it in the first hours, then the drug hammered the activity of the virus on the root, nothing at all poured out. If a little stretch (half day-a day), the rashes still appeared, but much less and passed all much faster than without treatment at all. By the way, usual Acyclovir in tablets did not take me at all, i.e. literally zero effect, about the various masqas generally keep quiet - this is clearly not for those who have everything seriously). But recently I notice that Valtrex is no longer so. Tolerance that developed to him in me or the quality of the drug itself worsened (remissions are no longer once or twice a year, but can come only after a couple of weeks after you have drunk a course, i.e. as if she did not accept anything (Sorry, very sorry. We will have to look for something even stronger (and, apparently, even more expensive).
