This may not be all of the side effects caused by Nasonex. If you experience any unusual symptoms or changes in your physical state, let your doctor know as soon as possible.
Side Effects In Children
Individuals as young as two may be prescribed Nasonex for allergy symptoms. Some studies indicate that the use of steroids in developing children can slow down normal growth. There is a possibility that this side effect of Nasonex could decrease the final adult height of a child who uses the medication for a prolonged time. If your child suffers from allergies, discuss the risks and benefits of Nasonex with his or her doctor before choosing the best treatment.
Pregnancy
Classified by the FDA as a pregnancy category C drug, mometasone and Nasonex could be harmful to an unborn child if it is taken during pregnancy, but there isn’t sufficient evidence to know for sure. If you are pregnant or plan to become pregnant, discuss your treatment options with your doctor to choose the best medication for you. Let your physician know if you become pregnant while taking Nasonex. Breastfeeding is not recommended while taking this medication, although it is not definite that mometasone can pass through breast milk.
Existing Conditions
Individuals with certain conditions may be at a greater risk of experiencing adverse side effects with Nasonex. Recent injuries to your nose or nose surgery should be discussed with your doctor before this medication is prescribed. You should also let your doctor know if you currently have any untreated infections. Taking Nasonex may make infections much more serious. Talk to your doctor about using Nasonex if you have any of the conditions below:
- Tuberculosis, either now or in the past
- Glaucoma, cataracts, or other eye disorders
- Herpes simplex virus that affects the eyes
- Sores, ulcers, or other skin conditions in the nose
- Liver disease
- Any other illnesses or infections
Other Medications
Most medications can be safely taken with Nasonex without experiencing any adverse reactions, but you should tell your doctor about all medications, vitamins, and supplements that you are taking on a regular basis. It is very important for your physician to be aware of any other steroid medications you may be taking, including oral steroids, such as prednisone, dexamethasone, etc., and inhaled forms like Flovent and QVAR. The dosage of these medications may need to be adjusted for you to safely take Nasonex.
Nasonex is not always the right allergy treatment option for everyone but for most individuals, it is safe and effective with very few side effects. It is important to wash your hands and avoid contact with individuals who are sick while taking this medication. People who are at a higher risk of infections or who take other medications that weaken or suppress the immune system may want to discuss other options with their doctor. Healthy adults rarely experience Nasonex side effects.
