Take Tadalis SX 20 mg approximately 30 minutes to 1 hour before engaging in sexual activity. This allows the medication time to be absorbed and start working effectively. Tadalis SX 20 mg does not automatically cause an erection without sexual arousal. Sexual stimulation is required for the medication to work effectively and produce an erection. Avoid excessive alcohol consumption while taking Tadalis SX 20 mg as it may increase the risk of side effects such as dizziness, headache, or low blood pressure. https://www.genericday.com/tadalis-sx-20-mg.html
