Avelox (moxifloxacin) is currently sold as a brand-name drug only. Because no generic versions became available after the expiration of the first patent, it is possible that other patents are preventing a generic version from being introduced. You should not purchase any generic Avelox drugs until an approved product is available.
Avelox® (moxifloxacin) is a prescription antibiotic medication. It belongs to a group of medications known as fluoroquinolones, or simply "quinolones" for short. It is a powerful "broad-spectrum" antibiotic that is effective against many different types of bacteria and infections. It is taken just once a day.
Avelox is made by Bayer HealthCare Pharmaceuticals, Inc. It is protected by patents that prevent any generic Avelox from being sold in the United States. Yet, if you search the Internet for "generic Avelox," you may find a number of companies selling it. The fact is that these medicines may be fake, substandard, and potentially dangerous. Generic Avelox may be available from another country, but there is really no way of knowing if you are getting genuine Avelox. You should not buy any generic Avelox until there is an approved version available.
The first patent for Avelox expired in December 2011. Yet, no generic versions are available. This strongly suggests that other, later-expiring patents are still protecting the drug from generic competition. The next patent for Avelox is set to expire in March 2014. This is the earliest predictable date that a generic version of the drug could become available.
However, other circumstances could come up to extend or shorten the exclusivity period of Avelox. This could include such things as lawsuits or other patents for specific Avelox uses. Once the medication goes off-patent, several companies will likely begin manufacturing a generic Avelox drug.
