The U.S. Food and Drug Administration has approved labeling changes for erectile dysfunction (ED) drugs in the class that includes Cialis, Levitra, and Viagra, to display more prominently the potential risk of sudden hearing loss, and to guide consumers on what to do if they experience sudden problems with their hearing.
In addition, the FDA plans to require the same changes in labeling for the drug Revatio, also a member of this drug class known as phosphodiesterase type 5 (PDE5) inhibitors. Revatio is used to treat pulmonary arterial hypertension (PAH). PAH is a serious medical condition in which continuous high blood pressure in arteries of the lungs weakens the heart muscle and often leads to right heart failure and death.
The FDA asked manufacturers of these drugs to revise product labeling after a very small number of patients taking the PDE5 inhibitors reported sudden hearing loss, sometimes accompanied by ringing in the ears and dizziness.
“Because some level of hearing loss is usually associated with the aging process, patients on these drugs may not think to talk to their doctor about it,” said Janet Woodcock, M.D., FDA's deputy commissioner for scientific and medical programs, chief medical officer, and acting director of its Center for Drug Evaluation and Research.
Patients taking Cialis, Levitra, or Viagra who experience sudden hearing loss should immediately stop taking the drug and seek prompt medical attention. Those using Revatio should continue taking their medication but should contact their health care provider for further evaluation. Because Revatio is used to treat a potentially life-threatening condition, the FDA does not recommend patients abruptly stop taking this medication but should consult their physician if they experience sudden problems with their hearing.
