Nasonex Side Effects
Some of the most common Nasonex side effects include headaches, viral infections, and nosebleeds. Fortunately, most people tolerate the drug without problems and when side effects do occur, they are typically minor and easily treated by you or your healthcare provider. However, some side effects of Nasonex should be reported to your healthcare provider right away, such as frequent nosebleeds, signs of an allergic reaction, or signs of steroid toxicity.
As with any medicine, side effects are possible with Nasonex® (mometasone nasal spray). However, not everyone who takes the medication will experience side effects. In fact, most people tolerate it quite well. If side effects do occur, in most cases, they are minor and either require no treatment or are easily treated by you or your healthcare provider.
(This article covers many, but not all, of the possible side effects with Nasonex. Your healthcare provider can discuss a more complete list of Nasonex side effects with you.)
Nasonex has been studied thoroughly in clinical trials in which the side effects of a group of people taking the drug are documented and compared to another group 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 Nasonex side effects included:
- Headaches -- in up to 26 percent of people
- Viral infections (such as the common cold) -- up to 14 percent
- Coughing -- up to 13 percent
- Nosebleeds -- up to 13 percent
- A sore throat -- up to 12 percent
- Painful menstrual cramps -- up to 5 percent
- Muscle or bone pain -- up to 5 percent
- Sinus infections -- up to 5 percent
- Vomiting -- up to 5 percent.
Other common side effects, occurring in 2 to 4 percent of people, included:
- Joint pain
- Chest pain
- Conjunctivitis ("pink eye")
- Upset stomach or indigestion
- Muscle pain
