SildenafilThis form:
Pronounced"sill-DEN-uh-fil" Common brand names:Viagra UsesSildenafil is used to treat male sexual function problems (impotence or erectile dysfunction-ED). In combination with sexual stimulation, sildenafil works by increasing blood flow to the penis to help a person get and keep an erection. This drug does not protect against sexually transmitted diseases (such as HIV, hepatitis B, gonorrhea, syphilis). To decrease your risk of infection, always use an effective barrier method (latex or polyurethane condom/dental dams) during all sexual activity. Consult your doctor or pharmacist for more details.

Sildenafil is also available in other brands and strengths for high blood pressure in the lungs (pulmonary hypertension).
