Side Effects of Mometasone/Formoterol
Common Side EffectsMometasone/formoterol has been studied extensively in clinical trials. In these studies, one group of people received the real medication, while another group was given a placebo (a "sugar pill" that does not contain any active ingredients). As a result, it was possible to see what side effects occurred, how often they appeared, and how they compared to the placebo.
In these studies, the most common side effects included:
- Inflammation or swelling of the nose or throat -- in up to 4.7 percent of people
- Inflammation of the sinuses -- up to 3.3 percent
- Headaches -- up to 4.5 percent
- Problems producing voice sounds, such as hoarseness -- up to 5.0 percent.
Mometasone/formoterol may also cause a yeast infection in the mouth or throat (thrush). This side effect occurred in up to 0.8 percent of people treated with mometasone/formoterol in clinical trials. Rinsing your mouth with water after each dose can reduce the risk of thrush.
Final ThoughtsYou may experience some or none of the side effects listed in this article. Unfortunately, there is no way for your healthcare provider to know beforehand if you will have problems with a medicine that you have never tried.
Therefore, make sure to let your healthcare provider know if you develop any side effects while taking mometasone/formoterol or if something "just does not seem right." While it may not be related to the medication, your healthcare provider will be able to diagnose and treat the problem.
