Tablet and inhaled controller medication refill frequencies in children with asthma.

Poor medication adherence is an important problem in children with asthma. This study compared prescription refill frequencies between tablet and inhaled medications in children aged 3 to 18 years with mild (n = 45) and moderate (n = 52) persistent asthma over 4 months. Refill frequencies were higher for tablet versus inhaled medications in both groups (mild: 69% vs. 31%, p = .02; moderate: 55% vs. 41%, p = .03). Refills peaked at the first month and incrementally declined (p < .05). Expanded asthma education did not increase refill frequency. Other methods of improving medication adherence may be warranted in this population.
