What is flunisolide nasal spray, and how does it work (mechanism of action)?
Flunisolide is a synthetic (man-made) corticosteroid. It is administered either as an oral metered-dose inhaler for the treatment of asthma (Aerobid) or as a nasal spray for treating allergic rhinitis. Corticosteroids are naturally- occurring hormones that prevent or suppress inflammation and immune responses. When given as an intranasal spray, flunisolide reduces watery nasal discharge (rhinorrhea), nasal congestion, postnasal drip, sneezing, and itching at the back of the throat that are common allergic symptoms. Eye symptoms such as itching and tearing that may be associated with allergy sometimes also are relieved. A beneficial response usually is noted within a few days but can take as long as 4 weeks. In asthmatic patients, the suppression of inflammation within the airways reduces the swelling caused by inflammation that narrows the airways. At the same time, mucus is reduced. Approximately 50% of flunisolide is absorbed into the blood. Flunisolide was FDA approved in September 1981.
What are the side effects of flunisolide nasal spray?
The most common side effects of flunisolide are:
- nasal irritation and itching,
- nausea or
- sore throat,
- nasal congestion,

No drug interactions have been described with nasal flunisolide
Is flunisolide nasal spray safe to take if I'm pregnant or breastfeeding?
Well-controlled studies on the use of flunisolide during pregnancy have not been done. Studies in animals have shown flunisolide to have damaging effects on the fetus. During pregnancy flunisolide should be avoided unless the physician feels that the potential therapeutic benefit justifies the added risk to the fetus.
It is unknown whether flunisolide accumulates in breast milk; however, it is known that other corticosteroids are excreted in breast milk. The effects on the child, if any, are unknown.
What else should I know about flunisolide nasal spray?
What preparations of flunisolide nasal spray are available?

How should I keep flunisolide nasal spray stored?
Flnisolide should be stored at room temperature between 15 C - 30 C (59 F - 86 F) and should be protected from heat, and direct light.

AllergyAn allergy refers to a misguided reaction by our immune system in response to bodily contact with certain foreign substances. When these allergens come in contact with the body, it causes the immune system to develop an allergic reaction in people who are allergic to it. It is estimated that 50 million North Americans are affected by allergic conditions. The parts of the body that are prone to react to allergies include the eyes, nose, lungs, skin, and stomach. Common allergic disorders include hay fever, asthma, allergic eyes, allergic eczema, hives, and allergic shock.
Asthma ComplexitiesThere are many unusual symptoms of asthma, including sighing, difficulty sleeping, anxiety, chronic cough, recurrent walking pneumonia, and rapid breathing. These symptoms may vary from individual to individual. These asthma complexities make it difficult to accurately diagnose and treat asthma.
Asthma in ChildrenAsthma in children manifests with symptoms such as coughing and wheezing. Rates of asthma in children are increasing. Asthma in children is usually diagnosed based on the description of symptoms. Lung function tests may also be used. A variety of medications are used for the treatment of childhood asthma.
Asthma MedicationsThere are two types of asthma medications: long-term control with anti-inflammatory drugs and quick relief from bronchodilators. Asthma medicines may be inhaled using a metered-dose inhaler or nebulizer or they may be taken orally. People with high blood pressure, diabetes, thyroid disease, or heart disease shouldn't take OTC asthma drugs like Primatene Mist and Bronkaid.
Asthma OverviewAsthma is a condition in which hyperreactive airways constrict and result in symptoms like wheezing, coughing, and shortness of breath. Causes of asthma include genetics, environmental factors, personal history of allergies, and other factors. Asthma is diagnosed by a physician based on a patient's family history and results from lung function tests and other exams. Inhaled corticosteroids (ICS) and long-acting bronchodilators (LABAs) are used in the treatment of asthma. Generally, the prognosis for a patient with asthma is good. Exposure to allergens found on farms may protect against asthma symptoms.
Asthma: Over The Counter TreatmentPatients who have infrequent, mild bouts of asthma attacks may use over-the-counter (OTC) medications to treat their asthma symptoms. OTC asthma medicines are limited to epinephrine and ephedrine. These OTC drugs are best used with the guidance of a physician, as there may be side effects and the drugs may not be very effective.

Perennial allergic rhinitis is a type of chronic rhinitis and is a year-round problem, often caused by indoor allergens, such as dust, animal dander, and pollens that may exist at the time. Treatment of chronic rhinitis and post nasal drip are dependent upon the type of rhinitis condition.
