VIAGRA is prescribed to treat erectile dysfunction (ED).
If you take any medicines that have nitrates in them
(like nitroglycerin for chest pain)—every day or even
once in a while—you should NOT take VIAGRA.
Discuss your general health status with your doctor to
ensure that you are healthy enough to engage in sexual
activity. If you experience chest pain, nausea, or any
other discomforts during sex, seek immediate medical help.
The most common side effects of VIAGRA are headache, facial
flushing, and upset stomach. Less commonly, bluish vision,
blurred vision, or sensitivity to light may briefly occur.
