Buy Famciclovir online, an antiviral medicine which is effective against the Herpes viruses, including herpes simplex 1 and 2 (cold sores and genital herpes) and varicella-zoster (shingles and chickenpox). Generic Famciclovir medication is part of a class of drugs called nucleoside analogs that mimic one of the building blocks of DNA. It blocks the growth of herpes virus in the body by preventing the replication of viral DNA that is necessary for viruses to multiply. This drug is active against the same viruses as Acyclovir but has a longer span of action. Therefore, it can be administered fewer times each day. It does not cure nor stop the spread of herpes infections, but it alleviates pain, burning, itching, tingling, and heals and prevents sores associated with herpes infections.
