"I have been using Symbicort for 8 months now. It has been a life changer for me. I was using my rescue inhaler at least 4 times a day previous to being put on Symbicort. I have only had to use it twice since starting on it. The only side effect I have had is that past few months I have been woken up every night by very bad cramps in my feet and my calves.  "
