Mometasone Precautions

Do not use mometasone if you are allergic to any of the ingredients in mometasone. 

Taking steroids may put you at a higher risk for infections. Mometasone is a nasal steroid and may suppress the immune system. Oral steroids (those taken by mouth) are more likely to cause immune suppression, but it is possible with mometasone. Before starting mometasone, let your doctor know if you have ever had tuberculosis or a herpes infection of the eye, as mometasone may allow these infections to worsen by weakening the immune system.

Mometasone, like all steroids, may slow the growth rate of children and teenagers.

Mometasone 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 mometasone, call your doctor right away.

Mometasone and Pregnancy

Tell your doctor if you are pregnant or plan to become pregnant.

The FDA categorizes medications based on safety for use during pregnancy. Five categories - A, B, C, D, and X, are used to classify the possible risks to an unborn baby when a medication is taken during pregnancy.

Mometasone falls into category C. In animal studies, pregnant animals were given this medication and had some babies born with problems. No well-controlled studies have been done in humans. Therefore, this medication may be used if the potential benefits to the mother outweigh the potential risks to the unborn child.


Mometasone and Lactation

Tell your doctor if you are breastfeeding or planning to breastfeed. It is not known whether mometasone passes into your breast milk or if it will harm your nursing baby.
