Tadfil 20 mg is usually taken 30 to 60 minutes before sexual activity, although its effects can last much longer than some other ED medications—often up to 24 to 36 hours. This longer duration allows greater flexibility in timing sexual activity compared to short-acting alternatives. The medicine does not increase sexual desire on its own. Sexual stimulation is still required for it to work effectively. Its performance can be influenced by lifestyle factors such as alcohol consumption, smoking, stress, poor sleep, and heavy or high-fat meals, which may delay or reduce its effectiveness.
