Buy Famvir online, an antiviral medication which is active against Herpes viruses, including herpes simplex 1 and 2 (cold sores and genital herpes) and varicella-zoster (shingles and chickenpox). Generic Famvir medication belongs to a group of drugs called nucleoside analogs that mirror one of the building blocks of DNA. It obstructs the spread of herpes virus in the organism by stopping the replication of viral DNA that is required for viruses to reproduce. This drug is effective against the same viruses as Acyclovir but has a longer period of action. Thus, it can be taken fewer times every day. It is not a cure for herpes infections nor does it stop their spread, but it relieves pain, burning, itching, tingling, and heals and prevents sores related to herpes infections.
