Malegra 120 is a medication used to treat erectile dysfunction (ED) in men. It contains the active ingredient sildenafil citrate, which is also the same active ingredient found in Viagra. Sildenafil citrate works by increasing blood flow to the penis, which can help men achieve and maintain an erection when sexually aroused. It's important to note that the effectiveness and safety of Malegra 120, like other sildenafil-containing medications, can vary from person to person. Higher doses of sildenafil may increase the risk of side effects, so it's crucial to use this medication only as directed by a healthcare provider.
