| If
you have heart problems severe enough to make sexual
activity a danger, you should avoid using Viagra.
Use it cautiously---if at all---if you've had a heart
attack, stroke, or life-threatening heart irregularities
within the past 6 months. Be equally cautious if you
have severe high or low blood pressure, heart failure,
or unstable angina (crushing heart pain that occurs
at any time).
If you take Viagra and develop cardiac symptoms (for
example, dizziness, nausea, and chest pain) during
sexual activity, do not continue. Alert your doctor
to the problem as soon as possible.
If you have a condition that might result in long-lasting
erections, such as sickle cell anemia, multiple myeloma
(a disease of the bone marrow), or leukemia, use Viagra
with caution. Also use cautiously if you have a genital
problem or deformity such as Peyronie''s disease.
If an erection lasts more than 4 hours, seek treatment
immediately. Permanent damage and impotence could
result.
If you have a bleeding disorder, a stomach ulcer,
or the inherited eye condition known as retinitis
pigmentosa, use this medication with caution. Its
safety under these circumstances has not yet been
studied.
Remember that Viagra offers no protection from transmission
of sexually transmitted diseases, such as HIV, the
virus that causes AIDS.
This drug is not for use by women. Its effects during
pregnancy have not been studied. |
