I have a bad rash on my neck, back and arms. It has recently developed. I have been taking Advair for approx. 2 years. Is this normal for a side effect to take this long to show up? The rash is almost like hives. My doctor has given me something called Elidel to help with the rash. It does work but not completely. The doctor did not even mention Advair as a possible reason for the rash because I have been taking it for 2 years.
