Megalis 20 tablet contains tadalafil, a medicine commonly used to treat erectile dysfunction (difficulty in achieving or maintaining an erection) and symptoms of benign prostatic hyperplasia (enlarged prostate) in men. It works by improving blood flow to the penis, which helps in getting a firm erection when there is sexual stimulation. In men with prostate enlargement, it can also help relieve urinary symptoms such as difficulty in passing urine.
