Manforce tablet are primarily used to treat erectile dysfunction (ED) in men. They contain Sildenafil Citrate, the same active ingredient found in Viagra, which helps increase blood flow to the penis, making it easier to achieve and maintain an erection during sexual arousal. Medical consultation is required before use, especially if you have heart problems, liver or kidney issues, or other health conditions. Sildenafil works by relaxing the blood vessels, which allows more blood to flow to the penis when sexually stimulated.
