Impotence is a condition prevents a man from either achieving or maintaining an erection. While it's frustrating and embarrassing, treatment is available; one such treatment is Viagra. Viagra helps relax muscles and increase blood flow to the penis, making an erection possible during sexual stimulation. Before men take this drug, it is important to understand its effects on the body.
Common Side Effects
The most common side effects of Viagra are relatively mild and tend to subside over time, but they should be reported to a doctor if they become persistent. According to emedtv.com, common side effects include headache, indigestion and the development of urinary tract infections. Diarrhea may occur as well, along with an unexplained rash and facial flushing. Men may also experience problems with vision, nasal congestion and dizziness.
Serious Side Effects

Men may also experience a temporary loss of vision, may faint or may notice a sudden loss of hearing.

And while an erection is the reason for taking Viagra, an erection that lasts for a prolonged period of time, either with or without pain, is an effect to be taken seriously. Men who experience any of these effects should call their doctor immediately.
