A University of Alabama study suggests impotency drugs, such as Viagra and Cialis, may produce an increased risk of optic nerve damage in certain men.
The small study by the Birmingham school suggests men with a history of heart attack or high blood pressure should be warned before taking such drugs.
The findings are based on a study of 76 men with optic nerve damage diagnosed as non-arteritic anterior ischemic optic neuropathy. NAION is the most common form of optic nerve damage in older US adults, with up to 6,000 people developing the condition every year.
Heart-Attack Link
Researchers said male study participants who had suffered a heart attack were 10 times more likely to develop optic nerve damage if they had taken Viagra or Cialis before their diagnosis.
