Cenforce 200 mg, a medication containing sildenafil citrate, is used to treat erectile dysfunction. The effects typically begin within 30 to 60 minutes of ingestion and can last for about 4 to 6 hours. This duration can vary based on individual factors such as age, metabolism, and overall health. While it helps achieve and maintain an erection during this period, sexual stimulation is necessary for it to work effectively. It's important to follow the prescribed dosage and consult a healthcare professional for personalized advice.
