Tadarise 20 mg contains tadalafil, which is used to treat erectile dysfunction (ED). It works by increasing blood flow to the penis, helping men achieve and maintain an erection when sexually stimulated. Unlike some other ED medications, tadalafil can be taken with or without food. The longer duration of action allows for more spontaneity in sexual activity during the 24–36-hour window. The effects of tadalafil can last for up to 24 to 36 hours. This is why tadalafil is often referred to as the "weekend pill" because its effects can last longer compared to other ED medications like sildenafil. Tadarise 20 mg typically starts working within 30 to 60 minutes after taking the pill.
