Cenforce 200, which contains sildenafil citrate, typically starts working within 30 to 60 minutes after consumption and can last for about 4 to 6 hours in the body. Its duration depends on factors such as dosage, age, metabolism, and overall health. The drug helps increase blood flow to the penis, allowing for a firm and sustained erection when sexually aroused. Alcohol, fatty foods, or certain medications may reduce its effectiveness or delay onset. While its effects gradually decrease after several hours, Cenforce should only be taken once a day and always under medical supervision for safe and optimal results.
