According to the U.S. Food and Drug Administration: men taking any of three erectile dysfunction drugs -- Viagra, Levitra or Cialis -- may be at increased risk for sudden hearing loss, prompting Food and Drug Administration officials to require label changes for the medications.

Now more then ever, men are seeking a safe alternative to prescription impotence drugs such as Viagra.

The FDA recently informed manufacturers that they must change verbiage on labels 'to display more prominently the potential risk of sudden hearing loss,' according to the FDA's Web site.

In addition to the erectile dysfunction treatment drugs Viagra, Levitra, and Cialis, labeling verbiage must also be changed for the medication Revatio, used to treat high blood pressure, which has the same active ingredient as the other drugs.

Men taking any of the erectile dysfunction drugs and who experience a sudden hearing loss should immediately cease using the drug and see their physician, the agency said.

Patients, both men and women, taking Revatio who experience a hearing loss should continue taking the drug, but see their physicians immediately. These patients should not discontinue immediately because it is used to treat a potentially life-threatening condition, the FDA said.

The FDA is requiring the label change for the entire class of drugs -- called Phosphodiesterase Type 5 Inhibitor, or PD-5 inhibitors.

Some men who need to treat their erectile dysfunction condition with medications such as Viagra have looked to the online pharmacies as a source of inexpensive, even cheap, Viagra.
