Quick Answer
Early warning signs include increased coughing, shortness of breath with mild activity, chest tightness, wheezing (especially when breathing out), waking up at night with cough, and needing your rescue inhaler more than twice a week. A peak flow reading below your personal best is another red flag. If your rescue inhaler isn't fully relieving symptoms within 20 minutes, come to urgent care. If it's not helping at all, call 911.
