Tadalista 40 mg is taken as needed, about 30 minutes to 1 hour before sexual activity. You may take it up to 4 hours before sexual activity. Do not take tadalafil more often than once daily. If you are also taking an alpha blocker medication (such as doxazosin, tamsulosin) to treat an enlarged prostate/BPH or high blood pressure, your blood pressure may get too low which can lead to dizziness or fainting.
