Sildenafil 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 man get and keep an erection. This drug does not protect against sexually transmitted diseases (such as HIV, hepatitis B, gonorrhea, syphilis). Consult your doctor or pharmacist for more details. Read the Patient Information Leaflet provided by your pharmacist before you start taking sildenafil and each time you get a refill. If you have any questions, ask your doctor or pharmacist. To treat erectile dysfunction-ED, take this drug by mouth as directed by your doctor, usually as needed. Take sildenafil at least 30 minutes, but no more than 4 hours, before sexual activity (1 hour before is the most effective). A high-fat meal may delay how quickly the drug begins to work.
Sildenafil is rapidly and almost completely absorbed following oral administration. Bioequivalence has been established between the 20-mg tablet and the 10-mg/mL oral suspension when administered as a single oral dose of 20 mg. Sildenafil oral tablet is a prescription medication used to treat erectile dysfunction ED and pulmonary arterial hypertension PAH. It's available as generic drugs and as the brand-name drugs.
