Viagra linked to hearing loss

A new study at the University of Alabama at Birmingham suggests the erectile dysfunction drug Viagra, and possibly other similar medications, may prompt long-term hearing loss among users,

In the May 18 issue of the Archives of Otolaryngology — Head and Neck Surgery, researchers discuss evidence supporting an association between the onset of hearing problems and Viagra. The medication is one of the so-called class of phosphodiesterase type 5 inhibitors (PDE-5i), which also includes Cialis and Levitra.

The finding follows the 2007 decision by the U.S. Food and Drug Administration to adjust labeling for such medications to more prominently display warnings about hearing loss risks. The move stemmed from reports that year regarding sudden hearing loss among users of these drugs. Study found men on medication were twice as likely to develop problem.
