nausea, and chest pain) during sexual activity, do not continue. Alert
your doctor to the problem as soon as possible.

such as sickle cell anemia, multiple myeloma (a disease of the bone
marrow), or leukemia, use Sildenafil non Rx 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.

transmitted diseases, such as HIV, the virus that causes AIDS.
