Cenforce 100 mg contains sildenafil citrate, a medicine used to treat erectile dysfunction (ED) in adult men. It works by supporting blood flow to the penis during sexual stimulation, which may help a man achieve and maintain an erection. Cenforce 100 mg does not increase sexual desire or cause an automatic erection. The appropriate sildenafil dose depends on individual health, current medicines, and treatment response, so it should be used only with guidance from a qualified healthcare professional.
