A new study from Washington University School of Medicine in St. Louis supports evidence that children with mild asthma can effectively manage the condition by using their two inhalers—one a steroid and the other a bronchodilator—when symptoms occur. This is in contrast to the traditional method of using the steroid daily, regardless of symptoms, and the bronchodilator when symptoms occur. The as-needed use of both inhalers is just as effective for mild asthma as the traditional protocol, according to the investigators.
