Nasonex Warnings and Precautions
Understanding Nasonex warnings and precautions prior to taking the medication can help ensure a safe treatment process. Some of these precautions include the possible risk of the drug suppressing the immune system, the safety of taking the drug when pregnant or breastfeeding, and the danger of the drug causing glaucoma or cataracts. Nasonex warnings and precautions also extend to people who are allergic to any components of the medication.
You should talk with your healthcare provider prior to taking Nasonex® (mometasone nasal spray) if you have:
- Not had chickenpox or the measles (or have not been vaccinated against them)
- Tuberculosis, herpes, or any other infections
- Glaucoma or cataracts
- Any allergies, including allergies to food, dyes, or preservatives.
Also, let your healthcare provider know if you are:
- Pregnant or thinking of becoming pregnant
Make sure to tell your healthcare provider about all of the medicines you take, including prescription and non-prescription medicines, vitamins, and herbal supplements.
Some warnings and precautions to be aware of prior to taking Nasonex include the following:
- If you are switching from an oral steroid to Nasonex (which is a nasal steroid), your healthcare provider should slowly decrease your dose of the oral steroid. Stopping an oral steroid too quickly can be very dangerous.
- Nasonex is a steroid and may suppress the immune system. Although this is more likely to occur with oral steroids, it is still possible with nasal steroids (such as Nasonex). Taking steroids may put you at a higher risk for infections. Certain infections (such as chickenpox or the measles) may be more dangerous if you are taking Nasonex. Let your healthcare provider know right away if you are exposed to chickenpox or the measles (if you have not had these infections and have not been vaccinated against them).
- Like all steroids, Nasonex may slow down the growth rate of children and teenagers. Contact your child's healthcare provider if you are concerned about a slow growth rate in your child.
- Nasonex can cause glaucoma or cataracts (conditions of the eyes) or may make these conditions worse.
- Before starting Nasonex, be sure to tell your healthcare provider if you currently have any type of infection. Also let your healthcare provider know if you have ever had tuberculosis or a herpes infection of the eye, as Nasonex may weaken the immune system, allowing these infections to worsen.
- Nasonex is considered a pregnancy Category C medication. This means that it may not be safe for use during pregnancy, although the full risks are not currently known (see Nasonex and Pregnancy).
- It is unknown if mometasone (the active ingredient of Nasonex) passes through breast milk. Therefore, if you are breastfeeding or plan to start breastfeeding, discuss this with your healthcare provider prior to taking the drug (see Nasonex and Breastfeeding).
- Nasonex can potentially interact with at least one other medication (see Nasonex Drug Interactions).
