asthma, maintenance
"After 6 weeks of taking Dulera, I find the relief effect wears down towards the 10th and eleventh hour.  My dosage is 2 puffs morning, 1 puff evening.  I'm 78 years old, and an asthmatic for 76 of those years.

Compared to Symbicort, Dulera "wears off" (as above) slightly faster.   Each is a good maintenance medication."
