Malegra 200 mg is a higher-strength medication used to treat erectile dysfunction (ED) in men. It contains sildenafil citrate, the same active ingredient found in Viagra, which is a PDE5 inhibitor. This medication works by increasing blood flow to the penis, allowing men to achieve and maintain a firm erection when sexually stimulated. Common side effects of Malegra 200 mg include headaches, flushing, stomach upset, and nasal congestion. Though rare, more serious side effects such as vision disturbances or priapism (a prolonged erection) require immediate medical attention.
