Cenforce-200 mg contains a very high 200mg dose of the medication sildenafil citrate, which is used to treat erectile dysfunction (ED) in men. A 200mg sildenafil dose is considered the maximum safe single dose. One Cenforce-200 mg tablet should be taken orally approximately 30-60 minutes before planned sexual activity. However, due to the high dose, it carries an increased risk of side effects like headache, flushing, indigestion, blurred vision, and priapism (persistent erection). Cenforce-200 mg is contraindicated in patients taking nitrate medications, with certain cardiovascular conditions, or severe liver/kidney impairment. Most men are instructed to start with a lower 25-50mg sildenafil dose, only increasing if needed with medical supervision. When used cautiously under a doctor's guidance, high-dose Cenforce-200 mg may benefit some men with ED that did not respond adequately to lower doses.
