I went to my Dr. and he told me that I have bronchitis with a little bit of wheezing. He prescribed doxycycline (antibiotic), and Prednisone (20 mg). I need to be on the prednison for 5 days. Take one tablet every other day. Has anyone else taken Prednisone for a short period? Did you have any bad side effects? The reason I ask is because I have acid reflux and take Prevacid. I also have irregular heartbeats (taken nothing for that). I read where Prednisone may speed up your heart rate. Is this true? If any one has taken before, would like your opinion or if you experienced anything.
