Megalis 20 mg is a prescription oral tablet containing tadalafil, a phosphodiesterase-5 (PDE-5) inhibitor. It is used primarily to treat erectile dysfunction (ED) in adult men; it’s also indicated for benign prostatic hyperplasia (BPH) symptoms and pulmonary arterial hypertension (PAH). It usually works within 30–60 minutes and may last up to 36 hours, offering greater flexibility compared to other ED medicines (WebMD).

How to Use
Take one 20 mg tablet orally with or without food, around 30–60 minutes before sexual activity. Do not take more than one dose in 24 hours.
