Be wary of steroids. It caused me many problems, 35 pound weight gain in 4 month, hypothyroidism to go off the charts, sever cramping in numerous muscles to the point a had to stop riding even typing for more then a few minutes. I saw a natural path and she helped figure out the causes of the athma. I have had to change my diet and still use Ventolin occasionally. A natural product I have found to work really well is RespirActin.
