Penegra is used to treat male sexual function problems (erection problems). Sildenafil relaxes muscles and increases blood flow to particular areas of the body. It is a phosphodiesterase type 5 (PDE5) inhibitor. It works by helping to increase blood flow into the penis during sexual stimulation. This helps you to achieve and maintain an erection.This drug is taken by mouth as needed 45min before sexual activity. Take only as directed, usually half a 100mg pill once daily as needed. Penegra works along with sexual stimulation to help achieve an erection.
