Cenforce 150 is a medication primarily used to treat erectile dysfunction (ED) in men. It contains sildenafil citrate, which is the same active ingredient found in Viagra.  Sildenafil citrate, the active ingredient in Cenforce 150, is a phosphodiesterase type 5 (PDE5) inhibitor. It works by increasing blood flow to the penis during sexual stimulation. This helps men achieve and maintain an erection sufficient for sexual activity. Cenforce 150 mg is typically taken about 30 to 60 minutes before sexual activity. It should not be taken more than once a day. The tablet should be swallowed whole with a glass of water. It can be taken with or without food, but high-fat meals may delay its onset of action. Cenforce 150 is effective in helping men with ED achieve and maintain an erection when sexually stimulated. However, it does not cure ED or increase sexual desire. It also does not protect against sexually transmitted infections (STIs).
