Drug interactions

If you miss a dose

If you miss a medicine dose, take it as soon as you remember. If it is almost time for your next dose, skip the missed dose. Take your next dose at its scheduled time, and continue your usual dosing schedule. Do not “double up” on doses to catch up.

How to take this medicine

This medicine can cause you to pass more urine. If your prescription says to take it once daily, take it in the morning. If you are to take more than 1 dose, take the last dose before 6 p.m. This will keep you from having to wake up in the middle of the night to use the bathroom.
