There is currently no generic version of Relpax available in the United States because it is protected by a patent. The first patent for Relpax expires in 2016, at which time a generic Relpax could be manufactured. However, there are other circumstances that could come up to extend that date past 2016, such as lawsuits. While generic Relpax may be available in other countries, there is really no way to determine if such products are genuine.
Generic Relpax: An OverviewRelpax® (eletriptan hydrobromide) is a prescription medication that has been licensed to treat migraine headaches. Relpax is part of a class of migraine medications called 5-HT agonists (or more commonly known as "triptans").
Relpax is manufactured by Pfizer. It is currently under the protection of a patent that prevents any generic Relpax from being manufactured in the United States. There may, however, be a generic version of Relpax available from another country, but there is really no way of knowing if such medications are genuine. Therefore, you should not buy any generic Relpax until there is an approved generic available.
