Generic Firazyr

Because a patent is in place until July 2014, companies are currently not allowed to make a generic version of Firazyr (icatibant). However, after this patent expires, a generic product may become available. Certain circumstances may come up, however, such as lawsuits or patents for new uses, which may delay the availability of a generic version of this drug.

Can I Buy Generic Firazyr?

Firazyr® (icatibant) is a prescription medication approved for the treatment of adults with a rare inherited condition known as hereditary angioedema (HAE). Firazyr is used to treat sudden swelling episodes that can occur in people who have this condition.
Firazyr is made by Shire US Manufacturing, Inc., for Shire Orphan Therapies, Inc. It is currently protected by a patent and exclusivity rights that prevent any generic Firazyr from being manufactured in the United States.

When Will a Generic Version Be Available?

The first patent for Firazyr expires in July 2014. This is the earliest predictable date that a generic version could become available. However, other circumstances could come up to delay or shorten this exclusivity period, including things such as lawsuits or other patents for new Firazyr uses. Once the patent expires, there may be several companies that manufacture a generic Firazyr drug.

Is Icatibant a Generic Firazyr?

No -- icatibant is the active ingredient in Firazyr, not a generic version of it. What can be confusing is that the active ingredient of a drug is often referred to as the "generic name." The generic name is different from a generic version of a medicine. In order for there to be a generic version, the original medicine must have gone off-patent, and another company besides the original manufacturer must make the product.
