Cenforce 100 mg is a medication used to treat erectile dysfunction (ED) in men. It contains Sildenafil Citrate, the same active ingredient found in Viagra. Cenforce works by increasing blood flow to the penis, helping men achieve and maintain an erection when sexually aroused. It typically takes effect within 30-60 minutes and can last for up to 4-6 hours. Cenforce 100 mg is an affordable alternative to brand-name Sildenafil medications, but should be used under the guidance of a healthcare professional.
