Cenforce FM 100 mg contains sildenafil citrate, a PDE-5 inhibitor that helps improve blood flow to the genital region by relaxing smooth muscles and widening blood vessels. When taken about 30–60 minutes before sexual activity, it can support men with erectile dysfunction (ED) to achieve and maintain firmer erections during sexual stimulation, potentially improving sexual performance, confidence, and satisfaction. This effect typically lasts several hours and offers a cost-effective alternative to branded ED treatments.
