How does the dosage of Symbicort compare with the dosage of Breo Ellipta?

But because Symbicort and Breo Ellipta are different drugs within the same drug class, their dosage is different. The dosage of Symbicort is 2 inhalations twice daily. The dosage of Breo Ellipta is 1 inhalation daily.

Keep in mind, one of these drugs may be more appropriate for you to take. Speak with your doctor to learn more about your options.
