Side Effects of Mometasone Inhalers
Although most people tolerate mometasone inhalers well, there are some potential side effects of the medication, such as upper respiratory tract infections, headaches, and an irritated or runny nose. While most side effects of mometasone inhalers are minor and can easily be treated by you or your healthcare provider, there are some more serious side effects that require immediate medical attention (including signs of an allergic reaction or worsening asthma symptoms).
As with any medicine, there are possible side effects with mometasone inhalers (Asmanex®). However, not everyone who takes the mometasone inhaler will experience side effects. In fact, most people tolerate the medication well. When side effects do occur, in most cases they are minor and either require no treatment or can easily be treated by you or your healthcare provider.
(This article covers many, but not all, of the possible side effects with mometasone inhalers. Your healthcare provider can discuss a more complete list of side effects with you.)
The mometasone inhaler has been studied thoroughly in clinical trials. In these studies, the side effects that occur in a group of people taking the drug are documented and are then compared to side effects that occur in another group of people not taking the medicine. As a result, it is possible to see what side effects occur, how often they appear, and how they compare to the group not taking the medicine.
In these studies, the most common side effects of mometasone inhalers included:
- Headaches -- in up to 22 percent of people
- An irritated, stuffy, or runny nose -- up to 15 percent
- Upper respiratory tract infections (such as the common cold) -- up to 15 percent
- A sore throat -- up to 15 percent
- Painful menstrual periods -- up to 9 percent
- Muscle pain or bone pain -- up to 8 percent.
Some other common side effects, occurring in 3 percent to 6 percent of people, included:
- Back pain
- Sinus infections
- Thrush
- Indigestion or heartburn
- Abdominal pain (or stomach pain)
- Nausea.
