Key takeaways
Dulera (mometasone / formoterol) and Symbicort (budesonide / formoterol) are both inhalers used to control asthma. Symbicort is also FDA approved to treat chronic obstructive pulmonary disease (COPD). They both contain two medications: a steroid and a long-acting beta agonist. Both inhalers can cause oral thrush, so you should rinse your mouth after each use. They also have similar side effects, such as headaches and respiratory infections. Dulera isn’t available as a generic, but Symbicort is available as a generic called Breyna.
