Cenforce is marketed as a sildenafil medicine used to treat erectile dysfunction (ED) in adult men. Sildenafil belongs to a class of medicines called PDE5 inhibitors. It works by increasing blood flow to the penis during sexual stimulation, which can help achieve and maintain an erection and may support greater confidence during intimacy. However, 130 mg is higher than the standard maximum recommended sildenafil dose of 100 mg for ED. Official prescribing information generally recommends 50 mg as the usual starting dose, with adjustment to 25 mg or 100 mg depending on effectiveness and tolerability. Sildenafil should not be taken more than once in 24 hours.
