Megalis 20 mg is a prescription medication containing Tadalafil as its active ingredient. Tadalafil is a PDE5 inhibitor that improves blood flow to the penis, enabling men to achieve and maintain an erection when sexually aroused. This medication is primarily used to treat ED but may also be prescribed for other conditions like benign prostatic hyperplasia (BPH) or pulmonary arterial hypertension in lower doses.
