What is triamcinolone acetonide nasal inhaler-spray, and how does it work (mechanism of action)?
Triamcinolone acetonide is a synthetic (man-made) corticosteroid. It is administered either as an oral metered-dose inhaler for the treatment of asthma (Azmacort), as a topical preparation for the skin (Kenalog; Aristocort) or as a nasal spray (Nasacort AQ) for relieving symptoms of rhinitis. Corticosteroids are naturally occurring hormones produced by the adrenal glands that prevent or suppress inflammation and immune responses. When given by intranasal spray, triamcinolone acetonide provides relief from allergy-induced watery nasal discharge (rhinorrhea), nasal congestion, postnasal drip, sneezing, and itching of the back of the throat which are symptoms associated with allergy. Approximately 50% of the triamcinolone acetonide is absorbed into the blood. A beneficial response usually is noted within a few days but can take as long as 4 weeks. The FDA approved Nasacort in July 1991.

Is triamcinolone acetonide nasal inhaler-spray safe to take if I'm pregnant or breastfeeding?
Serious complications (including cleft palate and still births) have been reported when oral corticosteroids were administered during pregnancy. It is not known if the small amounts of corticosteroids that appear in the blood following intranasal use carry the same risk. Triamcinolone acetonide use during pregnancy should be avoided unless the physician feels that the potential therapeutic benefit justifies the potential risk to the fetus.

Allergy (Allergies)
An 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
Asthma 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.
-
Hay Fever (Allergic Rhinitis)
Hay fever (allergic rhinitis) is an irritation of the nose caused by pollen and is associated with the following allergic symptoms: nasal congestion, runny nose, sneezing, eye and nose itching, and tearing eyes. Avoidance of known allergens is the recommended treatment, but if this is not possible, antihistamines, decongestants, and nasal sprays may help alleviate symptoms.

Allergy Treatment Begins at Home
Avoiding allergy triggers at home is one of the best ways to prevent allergy symptoms. Controlling temperature, humidity, and ventilation are a few ways to allergy-proof the home. Cleaning, vacuuming, and using HEPA air filters also helps control allergies.
