Nasonex and Breastfeeding

Although studies have shown that certain steroids pass through breast milk, it is not known if Nasonex passes through breast milk. However, it is not thought that the medication would pass through breast milk because very little Nasonex reaches the bloodstream. If you are taking Nasonex and breastfeeding at the same time, be sure to watch for any side effects in your child.

Nasonex and Breastfeeding: What Does the Research Say?

Nasonex is a steroid nasal spray. Studies have shown that other steroids pass through breast milk, but it is unknown if mometasone (the active ingredient of Nasonex) passes through breast milk. However, because very little Nasonex reaches the bloodstream (because it is a nasal spray), Nasonex is not expected to pass through breast milk (since medications must enter the bloodstream before they enter breast milk). If your healthcare provider recommends taking Nasonex while breastfeeding, be sure to watch for any side effects in your child.
