Viagra, Levitra, Cialis Linked to Hearing Loss

Now, the PDE-5 inhibitors or erectile dysfunction drugs have been associated with hearing loss in some patients. The studies which showed the link between hearing loss and the administration of Levitra, Viagra, and Cialis prompted the FDA to add a warning to the label of these drugs.
