Bothersome

If you experience any of these Viagra side effects, cease intercourse call your doctor:

• painful erection

Viagra side effects will occur more often as the dosage increases. The most serious reported side effect is blue tinted vision, of longer duration. Viagra can block the breakdown of cyclic GMP in the cone cells of the retina leading to perception of blue. Viagra can also cause dilation of blood vessels in other body parts, causing fainting and headaches.

Severe

A permanent erection. If you ever have an erection that lasts more than 4 hours, seek medical attention immediately so you don't end up with permanent damage.
