CLEVELAND, OH (WOIO) - 19 Action News has learned that there could be a troubling side effect to taking viagra.
Results of a new study show a link between long term hearing loss and the use of viagra.
Men first reported the side effect back in 2007.
Viagra's maker, Pfizer, placed a warning on its label then.
It's not clear if similar drugs like cialis and levitra cause the same hearing problems.
