Suhagra is a medication used to treat erectile dysfunction (ED) in men. It contains sildenafil citrate, which is the same active ingredient found in Viagra. Suhagra is taken orally with water. It is usually taken 30 minutes to 1 hour before sexual activity. Suhagra works by increasing blood flow to the penis during sexual stimulation, which helps men achieve and maintain an erection. It is effective for many men with ED, but its effectiveness can vary based on individual factors. The effects of Suhagra typically last for about 4 to 6 hours after ingestion.
