I have heard for a long time from many sources about the incurability of herpes, and have long been resigned to it, because the rash on the cubes and neck periodically appeared again and again, despite the treatment of them with attributed ointments and folk remedies. Famvir has become another drug that she bought with hope, despite the relatively high price. After three months, while the course of treatment was continuing, the results were completely satisfactory for me, I am satisfied. Olga, Zadonsk

Famciclovir was taken as one of the drugs for the treatment of shingles, and the problem was resolved rather quickly. Before that, I tried other medications that also helped, but after them a relapse occurred in time. After treatment, the second year of symptoms I do not notice, and I hope that the sore will not return. Daria, Ukhta
