Hi, I have a 9 year-old son who has asthma. He took Advair for a couple of months and has gained 55 lbs. It is almost impossible for him to lose. There are so many, many negative side effects from this product that if you are reading this you already know you should be off of it. Please, for your health, do not listen to your doctor regarding this medicine. It has changed my son's behavior and his weight gain has made his life miserable.
