:: How does Nasonex work?
When you are exposed to a substance that your body has identified as an allergen (intruder) or irritant, your immune system releases chemicals that cause inflammation of the nasal passages leading to symptoms such as sneezing, congestion and itchy, runny nose.
Although it is not known exactly how Nasonex works, it acts to reduce these inflammatory reactions, thereby stopping nasal allergy symptoms from occurring.
See our extensive Allergies FAQ for more information on
the immune system response to allergens .

:: How well does Nasonex work?
For seasonal outdoor and indoor perennial (year-round) allergies:
Nineteen clinical studies of over 3000 adults and adolescents have shown that Nasonex is an effective treatment for seasonal and perennial allergies. In these studies, patients receiving Nasonex had significantly reduced total symptom scores (scores used to measure sneezing, congestion, and runny, itchy nose) compared to non-medicated spray.
Four studies of almost 1000 patients ages 3-11 years have shown that Nasonex is an effective treatment for seasonal and perennial allergies. In these studies, patients receiving Nasonex had significantly reduced total symptom scores (scores used to measure sneezing, congestion, and runny, itchy nose) compared to non-medicated spray.
Two studies of almost 300 patients age 12 and older have shown that Nasonex is an effective treatment to protect against seasonal allergy symptoms before they begin. In these studies, patients who received Nasonex for 2-4 weeks before the start of pollen season had significantly lower total symptom scores (scores used to measure sneezing, congestion, and runny, itchy nose) when pollen season started compared to non-medicated spray.
Nasal Polyps:
Two studies of over 600 patients have shown that Nasonex is an effective treatment of nasal polyps. In these studies, patients who received Nasonex twice daily for four months had significantly less nasal congestion and improvement in nasal polyps compared to non-medicated spray.

:: What other precautions should I take when using Nasonex?
In addition to the possible side effects and drug intercations of Nasonex, please be aware of the following as they apply to you.
Chicken Pox and Measles: Take great care to avoid exposure to chicken pox or measles if you have not had them or been immunized against them. Patients taking corticosteroids such as Nasonex may be more susceptible to these infections. If you are exposed to or get chicken pox or the measles, call your doctor immediately.
Oral Corticosteroid Medications: If you have been taking an oral corticosteroid such as prednisone for a long period of time and switch to an intranasal corticosteroid such as Nasonex, your body may not heal as well after surgery, infection, or injury. In addition, other conditions you may have such as asthma or arthritis may get worse.
Infection: If you use Nasonex for an extended period of time there is a rare chance that you may develop a yeast infection in you nose and throat. Your doctor may periodically check you for signs of infection.
Nasal Septum Perforation and Increased Intraocular Pressure: If you use Nasonex for an extended period of time, there is a rare chance that you may experience perforations of your nasal septum (tears in the central divider of your nose) or increased intraocular pressure (increase pressure in the eyes). Your doctor may periodically check you for signs of possible changes in the lining of your nose.
Suppression of HPA: The use of Nasonex or other corticosteroids can rarely lead to the suppression of HPA, the hypothalamus, pituitary and adrenal gland. This is more likely to happen if higher than recommended doses are used. Your doctor may periodically check you for signs of these effects.
Growth of Children: The use of Nasonex or other corticosteroids can cause a slowing of the rate of growth for children. It is not known if this will change the final adult height. The growth of children should be monitored regularly.
Pregnancy and Breast Feeding: Nasonex should be used during pregnancy only if clearly needed. There are no adequate and well-controlled studies in pregnant women. It is not known if Nasonex is secreted in human milk. Women should notify their doctor if they become pregnant or intend to become pregnant while taking Nasonex.
Do NOT share your Nasonex prescription with others, this can be a very dangerous practice.
