Generic Xopenex HFA

Although Xopenex HFA is not yet available as a generic in the United States, a number of companies claim to sell "generic Xopenex HFA." These drugs could be dangerous, so do not purchase a generic form of Xopenex HFA until an approved version actually becomes available. The drug's first four patents have already expired, but it is unclear when a generic version will be produced.

Generic Xopenex HFA: An Overview

Xopenex HFA® (levalbuterol HFA) is a prescription medication used to treat asthma and other similar lung problems. It is part of a class of asthma drugs known as beta-adrenergic receptor agonists, or beta agonists for short.
 
Xopenex HFA is manufactured by Sepracor, Inc. No generic versions of Xopenex HFA are available in the United States. Yet, if you search the Internet for "generic Xopenex HFA," you may find a number of companies selling it.
 
The fact is that these medicines are fake, substandard, and potentially dangerous. There may be generic Xopenex HFA available from another country, but there is really no way of knowing if you are getting genuine Xopenex HFA or not. You should not buy any generic versions of Xopenex HFA until there is an approved generic available.
 

When Will Generic Xopenex HFA Be Available?

The first four patents for Xopenex HFA expired in 2009 and early 2010. It is unclear why generic versions are not yet available. Perhaps the other listed patents (the next of which is set to expire in July 2010) provide protection against generic competition.
 
When multiple patents are listed (as is the case with Xopenex HFA), it is often unclear which patents provide true protection against generic competition. Therefore, it is difficult, if not impossible, to predict when exactly a generic Xopenex HFA will become available.
