General Information on Terbutaline Dosing

Following are some considerations for people taking terbutaline:
 
  • Terbutaline comes in tablet form and is taken by mouth three times a day.
     
  • The medication can be taken with or without food. If terbutaline bothers your stomach, try taking it with food.
     
  • Terbutaline should be taken at the same times each day to maintain even levels of the drug in your blood.
     
  • For the medicine to work properly, it must be taken as prescribed. Terbutaline will not work if you stop taking it.
     
  • If you are unsure about anything related to your dosage or terbutaline dosing in general, please talk with your healthcare provider, nurse, or pharmacist.
