Tadalis SX 20 mg is a prescription medicine used to treat erectile dysfunction (ED) in men. It contains tadalafil, a phosphodiesterase type 5 (PDE5) inhibitor that works by increasing blood flow to the penis during sexual stimulation. This helps achieve and maintain an erection, but it does not increase sexual desire and only works when there is sexual arousal. A 20 mg dose is considered a higher-strength form of tadalafil and is usually prescribed when lower doses are not effective. It is typically taken about 30 to 60 minutes before sexual activity.
