Advair HFA and furniture

My daughter has been on Advair 100 since October 2004 when she first developed asthma. She is 4 1/2 years old. She recently started a cough and our doctor increased her Advair to 500 until the cough goes away. Within 2 days of the increased dosage she has become very agitated, thrashing herself against us and furniture. She screams at the top of her lungs and will not cooperate with us. We have to hold her down and try to soothe her until these "fits" pass or she is exhausted. We took her off the 500 Advair after we related the fits to the increased dosage (these fits came before when her dosage was increased to 500). Within 24 hours of going back to the 100 Advair she has returned to our sweet, loving 4-year old. I'm glad I thought to check out this site and found that excitedness and nervousness are side effects of Advair.
