"The rate of ibuprofen-sensitive asthma in children with mild or moderate asthma is low, the results of a study indicate. Nonetheless, because asthma is so prevalent in children, ibuprofen-sensitive asthma is a "public health concern," the investigators say.
In fact, "more than 100,000 children with asthma in the US may be at risk for (airway narrowing) following exposure to ibuprofen" (Motrin, Advil), Dr. Jason S. Debley told Reuters Health.
Because thousands of children with asthma take ibuprofen each year, often during an illness that can exacerbate asthma, the possibility that an asthmatic child may be sensitive to ibuprofen needs to be considered before it is administered, he emphasized."
