Cenforce 120 mg is marketed as a sildenafil product for erectile dysfunction (ED). Sildenafil is a PDE5 inhibitor that improves blood flow to the penis during sexual stimulation, helping men achieve and maintain an erection. However, 120 mg is above the standard maximum recommended sildenafil dose of 100 mg. Official prescribing information recommends 50 mg for most patients, with adjustment to 25–100 mg depending on effectiveness and tolerability. Sildenafil should be taken no more than once in 24 hours.
