Tazzle 20 mg is a medicine commonly containing tadalafil 20 mg, a phosphodiesterase type 5 (PDE5) inhibitor used to treat erectile dysfunction (ED) in adult men. Tadalafil works by increasing blood flow to the penis during sexual stimulation, helping an erection develop and remain firm. It does not increase sexual desire and does not cause an erection without sexual stimulation. Its effects may last for up to about 36 hours, although individual responses vary.
