Side Effects of Viagra

As with any medicine, side effects are possible with Viagra; however, not everyone who takes the drug will experience side effects. In fact, most men tolerate it well. If side effects occur, in most cases, they are minor, meaning they require no treatment or are easily treated by you or your healthcare provider.
 
The most common side effects include:
 
  • Headache -- in up to 16 percent of men
  • Facial flushing -- up to 10 percent
  • Indigestion (dyspepsia) -- up to 7 percent
  • Nasal congestion -- up to 4 percent
  • Urinary tract infections (UTI) -- up to 3 percent
  • Vision problems, including trouble telling the difference between blue and green, increased sensitivity to light, or blurred vision -- up to 3 percent
  • Diarrhea -- up to 3 percent
  • Dizziness -- up to 2 percent
  • Unexplained rash -- up to 2 percent.
     
If you have a heart or blood vessel disease (cardiovascular disease) or significant heart disease risk factors, you will have an increased chance of developing serious problems with the heart, brain, and blood vessels. These problems can result in a heart attack, stroke, or sudden death.
 
In people taking Viagra or other PDE5 inhibitors, there have been rare cases of a condition called non-arteritic anterior ischemic optic neuropathy (NAION). This condition can lead to sudden loss of vision in one or both eyes. If you experience any loss of vision while taking Viagra, contact your healthcare provider immediately (see Viagra and Blindness).
