Malegra 120 mg is a high-strength sildenafil tablet used to treat erectile dysfunction in men. It works by increasing blood flow to the penis during sexual stimulation, which helps improve erection quality and sexual performance. Malegra 120 mg should be taken only as prescribed, usually about 30 to 60 minutes before sexual activity, and not more than once in 24 hours. It should not be combined with nitrates or certain blood pressure medicines because that can cause a dangerous drop in blood pressure.
