Tadarise is an oral tablet containing 20 mg of tadalafil. It is to be swallowed whole and should not be crushed, chewed, or broken. It should be taken at least 30 minutes before sexual activity to ensure adequate time for the drug to work. Taking the medication too close to sex will decrease the effectiveness of the medication. If you are taking a higher dose than recommended, you should stop taking Tadarise 20 or reduce your dosage.
