Reviews about Valtrex

As is known, the herpes simplex virus is widely spread in modern society, so the drugs that are designed to fight it are very popular. A large number of medicines is created for the treatment and prevention of possible recurrences of the disease.
At the same time, opinions and opinions about Valtrex differ markedly, that is, there are a lot of both positive and negative reviews. For example, someone helps the drug to almost completely get rid of the symptoms of herpes for many years, and someone has another development of the infection happened a couple of weeks after the completion of treatment. And according to some patients, this medicine should be taken when the disease recurs.
It should be noted that treatment of viral infections by itself is a rather complex and strictly individual process. Although, as the reviews on the forums show, herpes is very common and for many people is considered a common cold, in fact, such a virus significantly undermines human health, complicating the course of other diseases.
The use of antiviral drugs usually occurs in the same way. Therefore, the doctors' opinions about Valtrex do not contain any meaningful information. Sometimes they recommend the simultaneous use of different forms of drugs, for example, ointment and tablets.
In any case, the basic principle of treating recurrences of the disease involves a rapid onset of antiviral use as soon as the first symptoms appear. Many people suffering from herpetic or other chronic viral infections have a lowered immunity. For this reason, proper treatment should include additional measures to strengthen the protection of the human body.
