I take Dulera. When I started having mild asthma symptoms 7 months ago, I started running again, thinking I was just out of shape. I've checked my resting heart rate to check progress, and even before my diagnosis and meds my heart rate dropped, and stayed low while on Pulmicort. It's increased a bit after 4 weeks on Dulera. Since heart rate is a measure of fitness, am I less fit now that my heart rate is higher?
