Generic Imitrex

Imitrex Generic : an introduction

Sumatriptan is the generic name for Imitrex. That means that the brand name from the first manufacturer of sumatriptan was Imitrex and it was made and marketed by GlaxoSmithKline. The branded version of Imitrex became available as a generic in 2009. Each branded prescription drug also has a generic name, which you will often see in parenthesis following the brand name.

When the patent exclusivity for a brand name product expires, often times multiple generic manufactures seek approval from the FDA to manufacture and sell generic versions of the branded drug. When a drug like Imitrex becomes generic it is typical for the generic products to be priced much lower than the branded product. As such, most insurance plans offer lower patient co-pays for generic drugs, like Imitrex, than they do for branded drugs.

There are many manufacturers of generic Imitrex. They include Teva, Sandoz, Mylan, Roxane Par and others. Generic Imitrex is widely available and is included in the discounted generic programs of many pharmacies.

Even though a prescription drug has a generic name, this does not always mean it is available in a generic form at the pharmacy. Often prescription medicines are referred to either by their brand name (only one manufacturer holds the exclusive right to make and market the product using the brand name) like Imitrex or by the generic name in this case, sumatriptan.
