Now, in order to get a true sense of what Viagra’s side effects are, it is necessary to compare problems reported by men taking Viagra and men taking placebo pillls. If Viagra-treated men have headaches more often than those men who received placebo pills, then headaches are considered a Viagra side effect. Symptoms that occur with equal frequency in both Viagra- and placebotreated men cannot be considered to be Viagra side effects.

From this type of survey, we can determine that certain side effects, headache and facial flushing, for example, are more common with Viagra, whereas other problems like dizziness and stuffy nose occur about as often with Viagra as with placebo. A handful of men do have Viagra-triggered headaches or flushing. Even fewer have visual distortions and see blue images for a period of time.

Only a handful of men chose to discontinue treatment because of Viagrainduced side effects. In one recent study, 31 of 316 men receiving Viagra stopped treatment because of side effects. In the same study, 36 of 217 placebo-treated men also decided to stop treatment because of “side effects.

This is in striking contrast to other impotence therapies like penile injection, where many men experience erections initially but despite this favorable response do not continue with treatment. For penile injection, the dropout rate often approaches 70 percent.

Notably missing from this list of adverse effects are life-threatening or serious adverse events. Why? Was Pfizer, the drug company that developed and marketed Viagra, trying to cover up something? Apparently not.

From the beginning, Pfizer was concerned that its product might be used inappropriately and was fierce in advising physicians to screen patients carefully before prescribing Viagra. Men who routinely use a class of medication called nitrates like nitroglycerin or isosorbide (Isordil), commonly prescribed to prevent or alleviate a form of heart pain called angina pectoris, should not take Viagra. No ifs, ands, or buts.
