Taking steroids may put you at a higher risk for infections. Nasonex is a nasal steroid and may suppress the immune system.

Before starting Nasonex, let your doctor know if you have ever had tuberculosis or a herpes infection of the eye, as Nasonex may allow these infections to worsen by weakening the immune system.
Nasonex, like all steroids, may slow the growth rate of children and teenagers.
Nasonex can cause glaucoma or cataracts or worsen these conditions.
Avoid exposure to measles and chicken pox. If you are exposed to measles or chicken pox while using Nasonex, call your doctor right away.
