Tadalafil tablets are medications used to treat erectile dysfunction in men. Long-term use is generally not recommended, and patients must follow their doctor’s instructions closely when using the medication. Tadalafil tablets are usually taken about half an hour before having sex, and sexual stimulation is required for the drug to take effect.
