Suhagra 50mg contains sildenafil citrate, which belongs to a class of medicines known as phosphodiesterase type 5 (PDE5) inhibitors. When a man is sexually aroused, this medicine helps relax the blood vessels in the penis, allowing more blood to flow into it. This increased blood flow helps produce a firm and lasting erection suitable for sexual activity.

The effectiveness of Suhagra 50mg depends on sexual stimulation—it will not cause an erection on its own. It begins to work within 30 to 60 minutes after consumption and can last for up to 4 hours. It is important to take it exactly as prescribed and not more than once in a 24-hour period.
