Specific Precautions and Warnings With Mometasone Nasal Spray
Some warnings and precautions to be aware of prior to taking mometasone
nasal spray include the following:
- If you are switching from an oral steroid to mometasone nasal spray (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.
- Mometasone nasal spray 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 mometasone nasal spray). 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 mometasone nasal spray. 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, mometasone nasal spray 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.
- Mometasone nasal spray can cause glaucoma or cataracts (conditions of the eyes) or may make these conditions worse.
- Before starting mometasone nasal spray, 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 mometasone nasal spray may weaken the immune system, allowing these infections to worsen.
- Mometasone nasal spray 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 mometasone nasal spray) 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).
- Mometasone nasal spray can potentially interact with at least one other medication (see Drug Interactions With Mometasone Nasal Spray).
