Review about Zovirax.
The appearance of the common cold on the lip I immediately went to the doctor. Rashes appeared at me for the first time and I decided to undergo full treatment to get rid of them forever. The doctor prescribed several drugs-analogues, of which I chose Zovirax, as I trust the manufacturer – many of the UK drugs are very high quality. Zovirax helped me well. I used the cream for 7 days and since then herpes did not appear.
The herpes I have regular and continuous discomfort. I decided to completely get rid of it. The doctor prescribed me a course of taking Zovirax tablets. I’ve been taking them for 10 days, a little longer than I needed to, but after that, the rashes don’t bother me. In addition, I now monitor my immune system so as not to get a relapse.
One day I had genital herpes, which is constantly scratched, sick and was infected for a partner. So immediately went to the pharmacy, where I was advised Zovirax tablets. It was not the cheapest of all the analogues, but the effect was worth it. On the third day, the number of rashes decreased markedly, and after a couple of days all the crusts dried up and disappeared. Treatment was fast and effective.
