Malegra 200 mg is marketed for erectile dysfunction (ED) and contains sildenafil, a phosphodiesterase type 5 (PDE5) inhibitor. Sildenafil works by increasing blood flow to the penis during sexual stimulation, helping some men achieve and maintain an erection. It does not increase sexual desire and cannot produce an erection without sexual stimulation. However, 200 mg is above the usual recommended maximum dose of sildenafil for ED. Taking a higher dose does not necessarily provide better results and may substantially increase the risk of side effects. Men should not use Malegra 200 mg unless a qualified healthcare professional has specifically advised it.
