About Viagra

Viagra (sildenafil citrate) is a prescription medication indicated for
the treatment of ED. Viagra is available only from health care
providers and should always be used in accordance with its approved
labeling. Viagra is contraindicated in patients who use nitrates in any
form at any time.

Patients should discuss their general health status with their doctors
to ensure that they are healthy enough to engage in sexual activity. If
patients experience pain, nausea, or any other discomfort during sex,
or an erection that lasts longer than four hours, they should seek
medical help.

The most common side effects of Viagra (sildenafil citrate) are
headache, facial flushing and upset stomach. Less commonly, bluish
vision, blurred vision or sensitivity to light may briefly occur.

Patients with recent serious cardiovascular events, hypotension or
uncontrolled hypertension or retinitis pigmentosa did not participate
in pre-approval clinical trials. In these patients, physicians should
prescribe Viagra with caution. The use of Viagra offers no protection
against sexually transmitted diseases, including human immunodeficiency
virus (HIV).
