Viagra Problems

Erectile dysfunction (ED) is a condition in which a man is consistently unable to sustain an erection that is firm enough for sexual intercourse. Viagra® (sildenafil citrate) is often used to treat this problem. It comes in tablet form, and is taken as needed (but no more than once a day).
 
Most men have no problems with Viagra; however, adverse reactions are possible. In clinical studies, commonly reported side effects included headaches, indigestion, and facial flushing. Such reactions are usually mild and are easily treated.
 
However, there are some potentially serious problems with Viagra that can occur. For example, make sure to contact your healthcare provider right away if you have loss of vision, signs of a heart attack, or hearing loss.
