About Me
Sildenafil is used to treat problems with male sexual function (impotence or erectile dysfunction-impotence). In combination with sexual stimulation, sildenafil increases blood flow to the penis to help a man achieve and maintain an erection. To treat erectile dysfunction, take this medication 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 most effective). Do not take more than once a day. A high-fat meal may slow down how quickly the medicine starts to work. The dosage is based on your medical condition, response to treatment, and other medications you are taking. Be sure to tell your doctor and pharmacist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products).
