Dulera Side Effects
Headaches and inflammation or swelling of the nose or throat are some of the most common side effects reported with Dulera. In most cases, reactions to this medication are minor and are typically easy to treat. However, it is possible to experience potentially serious side effects. Contact your healthcare provider immediately if you have problems such as chest pain, vomiting, or difficulty breathing.
As with any medication, Dulera® (mometasone/formoterol) can cause side effects. However, not everyone who uses the medication will have problems. Most people tolerate it quite well. If side effects do occur, in most cases, they are minor and either require no treatment or are treated easily by you or your healthcare provider.
(This article covers many, but not all, of the possible side effects with Dulera. Your healthcare provider can discuss a more complete list with you.)
Dulera 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.
Dulera 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 Dulera in clinical trials. Rinsing your mouth with water after each dose can reduce the risk of thrush.
