Malegra 200 mg contains sildenafil, sildenafil can improve erections in men with erectile dysfunction by increasing blood flow to the penis during sexual stimulation. However, 200 mg is above the usual maximum recommended sildenafil dose of 100 mg once daily. Taking Malegra 200 Mg does not necessarily improve effectiveness and can increase the risk of side effects such as headache, flushing, dizziness, vision changes, and low blood pressure. For safety, a 200 mg dose should not be used unless specifically prescribed by a qualified healthcare professional.
