Suhagra 100 is a medication used for the treatment of erectile dysfunction (ED) in men. It contains the active ingredient sildenafil citrate, which is a phosphodiesterase type 5 (PDE5) inhibitor. Sildenafil citrate works by increasing blood flow to the penis during sexual stimulation, helping men achieve and maintain an erection.  Suhagra 100 is typically taken about 30 minutes to 1 hour before anticipated sexual activity. It should be taken with water and can be taken with or without food. The exact timing and conditions may vary based on individual factors.
