C., I am a respiratory therapist and an asthma educator. Reactive airway disease is just another way of saying asthma. While you may be right that this is just a one time thing and that your daughter may have been misdiagnosed, be very aware that she may have asthma and if she does, you need to take it very seriously. Reactive airway disease is difficult to diagnose in children, other than by symptoms and patient history. Usually, definitive diagnosis can not be made until the child is at least five or six and is able to do a pulmonary function test. However, if your daughter has a history of recurrent upper airway respiratory infections, accompanied by wheezing, a crouppy or barking sounding cough, frequent night time awakenings with a cough, difficulty with breathing or catching her breath when she is running...then you should be very aware that she may have asthma. Asthma is a chronic condition that is characterized by episodes of difficulty breathing, and cough. The medications that the doctor prescribed are a bronchodilator that will help her keep her airways open (Albuterol) and a corticosteroid that will keep inflammation in the airways under control (Flovent). The Albuterol is the rescue medicine and should be used whenever she is coughing hard or can't catch her breath, or as prescribed (if he said to take it every four hours, then give it every four hours). The Flovent is the prevention medicine, and should be used to keep her from having difficulty breathing and coughing. Never use the Flovent as a rescue medication. As you said, you may want to get a second opinion if this seems like an isolated case of bronchitis, but that depends on how much you trust your doctors opinion. If you're not happy with your doctor, and comfortable with him, then you should try and find a doctor that you feel better about anyway. My concern is that you will not take this diagnosis seriously, and risk your daughters life. Each year approximately 5000 people die from asthma, and that is too many. I always like to give people these warning signs. If your daughter stops playing or acting normally because she is trying to breathe, if your daughter's neck and tummy and around her ribs sucks in with each breath, if she appears to be struggling to breathe, or if her lips or nail beds look blue or grey, give her some of the Albuterol immediately and then get her to an emergency room. These are all signs that your daughter is in serious trouble and you need to be very aware that she is in need of emergency intervention. Good luck with your daughter and write back if you have further questions. D.
