Cenforce 25 mg is a sildenafil product containing sildenafil citrate 25 mg, a PDE-5 inhibitor used to treat erectile dysfunction (ED). Sildenafil improves blood flow to the penis during sexual stimulation, helping achieve and maintain an erection. It does not increase sexual desire and requires sexual stimulation to work. For ED, sildenafil is commonly started at 50 mg when needed, but the dose can be reduced to 25 mg depending on effectiveness, side effects, age, or certain medical conditions. The maximum recommended dose is 100 mg once per day.
