In our country they are not so cheap. When I decided to try them I calculated the cost of the all antivirals according to the Gacek treatment protocol, so: Valtrex - the cost for 9 first weeks - 541 eur (642 usd), maintenance dose per month - 129 eur (153 usd). Valacyclovir - the cost for 9 first weeks - 385 eur (457 usd), maintenance dose per month - 92 eur (110 usd). Acyclovir - the cost for 9 first weeks - 135 eur (160 usd), maintenance dose per month - 16 eur (19 usd). So it's quite a money, especially when you need to take AVs for a long period of time. Besides, in our country there is no medical insurance for antivirals to treat MD. The only one drug which is approved for MD in Europe and in Canada is Betaserc (Mylan producer, original), which costs per month is about 16 eur (19 usd). So if the pharmaceutical companies follow the money, which is logical, why don't they follow the money with AVs in the MD case? Especially Milan producer, which followed the money with Betaserc, but not with AVs which they are also producing and the more - antivirals offer much more money than Serc?
