I dont recall her having rapid heart rate with this
symbicort, but she has had good luck with Flovent
for several years.. but it just wasnt cutting it the past year for her, and needed to advance to something else, but for many years it worked pretty good. She initally experience the rapidness but it subsided. Now she is on the symbicort and hates that it is a powdery- like substance, and is still experiencing wheezing.
