Instructions for use

The therapeutic effect is achieved by converting the active substance of the drug (valacyclovir) to another substance (acyclovir) as a result of reaction with the enzyme varacyclovir hydrolase produced by the liver.

The main function of acyclovir is the inhibition of the synthesis of the DNA of the herpes viruses.

Indications for use

Valtrex can be used to prevent the recurrence of skin infections triggered by any varieties of herpes simplex, as well as to prevent transplant rejection during organ transplants caused by cytomegalovirus infections.

Herpes on the lip bothers me with an enviable periodicity: once every one and a half to two years. I tried and Acyclovir, and Zovirax, and some other ointment, the names of which I do not remember, but to no avail. And now the herpes came to me once again while on holiday abroad. The pharmacy pharmacist in broken English said that they all are treated with Valtrex. I decided to try. On the first day I drank as many as 3 tablets (for sure!), And in the following days, as expected, two each. Two days later, herpes was blown away, leaving a small spot, and after a week it was gone. The side effects described in the instructions may not faintly frighten, but nothing like this has manifested to me. Now, if the herpes decides to visit me again, I have Valtrex for him.

For me, Valtrex is the best remedy for herpes. I tried to replace it with cheaper medicines - the effect is not the same. But now I know that I will not waste my money. Acne on the lip is already on the third or fourth day, despite the fact that Metrogil did not take them for a week before. Angelina, 40 years old

These pills helped me even run herpes win. I had never encountered this filth before, and when something puffed up on my lip, I thought it was a pimple. Well, it became my habit to treat it with metrogyle and instead of one pimple I received several bubbles. In time, a friend came to visit me and immediately diagnosed herpes. And she advised Valtrex. I added acyclovir to the pills (I also bought it at the pharmacy), and these two remedies quickly relieved me of herpes. Lyudmila, Saratov

By and large, herpes is easier to prevent than to cure. But if prevention has failed, it is necessary to be treated. I tried Valtrex on myself and the experience was successful: the inflammation subsides, and after taking the course I forget about herpes for a long time. By the way, it is not always possible to find it in city pharmacies, so I order it via the Internet. The price is normal, it is consistent with the quality of the drug. The main thing is to save herpes! Vitaly, Murmansk
