Generic Valtrex (Valacyclovir 500 mg) guide:
What is the preparation sold as Generic Valtrex?
Valtrex is nothing besides a registered trade name for the preparation officially named Valacyclovir. Valacyclovir is an antiviral agent used for the therapy and prophylaxis of various forms of herpes. Worldwide it is accessible under a variety of trademarks though you can easily find it if you ask any pharmacist for Generic Valtrex, although it is not an official or registered name. The brand name plus the word generic is a common term introduced by the World Health Organization to help people find cheaper analogs of the branded medicines they need. In fact, it would be more correct to call these medicines generics of Valacyclovir but it is easier for people to remember the short brand name than the longer names of the active substances.
In short, Generic Valtrex is the same Valtrex simply made by another pharmaceutical company and marketed under a different trade name.
Why people prefer generics? Are generics as effective as the brand medicines?
The reason more and more people every year opt for generics instead of the branded medicines is the lower price. The low price of generics isn’t caused by the inferiority of the medicine. The manufacturers of generics find ways to save on the development and research, production, and marketing without compromising the quality of the preparation. In fact, they do not invest money in the research because they utilize the formula of the branded preparation. As for the lower production costs, they usually place their facilities in the countries where the production, in general, is less expensive. Generic drug makers also do not advertise or promote their drugs as people can easily find them even without it when they look for the cheaper version of the medicine their doctor prescribed simply asking a pharmacist to give them generic instead of the branded preparation.
