GENERIC NAME: triamcinolone acetonide nasal spray/inhaler

BRAND NAME: Nasacort; Nasacort AQ

DRUG CLASS AND MECHANISM: 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) or inhaler (Nasacort) for relieving symptoms of rhinitis.

Corticosteroids are naturally occurring hormones that prevent or suppress inflammation and immune responses. When given by intranasal spray or inhaler, triamcinolone acetonide provides relief from allergy-induced watery nasal discharge (rhinorrhea), nasal congestion, postnasal drip, sneezing, and itching of the back of the throat. Sometimes the symptoms associated with allergy also are relieved. 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.

DRUG INTERACTIONS: No drug interactions have been described with nasal triamcinolone.

PREGNANCY: 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 risk to the fetus.

SIDE EFFECTS: The most common side effects following nasal inhalation of triamcinolone acetonide are nasal irritation and itching, increased cough, nausea or vomiting, sore throat, nasal congestion, sneezing, nasal burning, bloody nasal discharge, and nasal dryness.
