 side effects  of Viagra
|
• Nearly three months after approving Viagra, the Food and Drug Administration
had received about 100 reports of men suffering serious adverse reactions or dying after taking the impotence drug, but regulators remain convinced Viagra is safe.
• Altogether, as of mid-June, the FDA had received about 30 reports of men dying after taking Pfizer Inc.'s blockbuster impotence drug. Most were elderly, with other health problems. In addition to the deaths, the reports show seven men had heart attacks, eight suffered strokes, four blacked out and six had vision problems, according to government reports obtained through the Freedom of Information Act.
• The reports, however, probably cover
only a fraction of the cases of serious side effects suffered by the sizteen million men
who have used Viagra since it hit the market in April. The government doesn't require reports on serious adverse reactions, and public-health experts figure that the FDA typically receives reports on only 1% to 10% of these reactions.
