If you have a serious asthma attack (exacerbation), your doctor may prescribe a short course of oral c orticosteroids. When used orally for less than two weeks, the side effects of corticosteroids are less likely, but when used for many months, they can have a serious and permanent effect. After the severe symptoms of your asthma attack have been successfully treated and controlled, your doctor will work with you to minimize your need for prednisone in the future. Faithfully taking an inhaled corticosteroid every day is the most commonly successful method to do this.
FENO levels ranged from 7-215 ppb (median 28 ppb) in 325 patients. Higher FENO levels significantly correlated with more SABA dispensings and OCS courses in the past year, lower FEV(1)% predicted levels, but not ACT score. FENO highest (≥48 ppb) versus lowest (≤19 ppb) quartile values were associated independently in the past year with ≥7 SABA canisters dispensed (relative risk=, 95% CI=-) and total number of SABA canisters dispensed (IRR=, 95% CI=-) and with ≥1 OCS course (relative risk=, 95% CI=-) and total number of OCS courses (IRR=, 95% CI=-). The significant independent relationship of higher FENO levels to increasing SABA dispensings and OCS courses was confirmed by linear trend analyses.
Quick-relief or rescue medications are used to quickly relax and open the airways and relieve symptoms during an asthma flare-up, or are taken before exercising if prescribed. These include: short-acting beta-agonists . These inhaled bronchodilator (brong-koh-DIE-lay-tur) medications include albuterol (ProAir HFA, Ventolin HFA, others), levalbuterol (Xopenex HFA) and pirbuterol (Maxair Autohaler). Quick-relief medications do not take the place of controller medications. If you rely on rescue relief more than twice a week, it is time to see your allergist.
