Use of Cough and Cold Medications in Severe Bronchiolitis before and after a Health Advisory Warning against Their Use.

We compared the use of cough and cold medications in 2 multicenter studies of young children hospitalized with bronchiolitis before and after the 2008 Food and Drug Administration cough and cold medications advisory. Although cough and cold medication use decreased after the advisory, nearly 20% of children age 12-23.9 months with severe bronchiolitis received cough and cold medications.
