How does Valcyclovir (Generic Valtrex) work?
Valtrex exerts its effect on the viral enzyme known as DNA polymerase and blocks it. The herpes viruses cannot work or replicate from one cell to another without this DNA polymerase. Valcyclovir thereby aids treatment by restricting the spread of the herpes viruses. The FDA too has studied this effect of Valtrex and approved it for treatment of herpes.

Side effects of Valcyclovir (Generic Valtrex)
Whether you are taking Valtrex or its generic alternatives, there are bound to be some Valtrex side effects. Among the most common ones that have been reported among adult patients are included headache, abdominal pain, diarrhea, reduced kidney function, nausea and vomiting, and disturbed liver functions.

If you follow the dosage as prescribed by your doctor, the symptoms of these Valtrex side effects are generally mild. However, if you overdose, or change your medication dose without talking to your doctor, it might lead to dangerous consequences. While Valtrex is not considered dangerous during pregnancy, chances of a pregnant woman passing herpes to the unborn child are high; so pregnant women should get treatment for their herpes lesions at the earliest. The medication should also not be taken after alcohol consumption as the effects of the combination are not exactly known.
