Acetaminophen does not aggravate young children’s asthma

A head-to-head comparison with ibuprofen refutes a link between acetaminophen and asthma exacerbations.

Your toddler is screaming in pain. Her forehead is burning. You rush to your local drugstore. What do you get — Tylenol or Motrin? And by the way, she also has asthma.

Recently, many parents have been under the impression that acetaminophen (Tylenol, etc.) may do more harm than good in young children with asthma.

“There’s been a lot of ‘smoke’ about this, based on a lot of retrospective observational data,” says Wanda Phipatanakul, MD, MS, of Boston Children’s Hospital’s Division of Allergy and Immunology.

The studies in question concluded that the common over-the-counter remedy can cause asthma exacerbations. Reviewing these studies, one author concluded, “Until future studies document the safety of this drug, children with asthma or at risk for asthma should avoid the use of acetaminophen.”

The Acetaminophen Versus Ibuprofen in Children with Asthma (AVICA) trial, led by Phipatanakul for the National Heart, Lung and Blood Institute’s AsthmaNet now sets the record straight.

Can asthma be nipped in the bud?

Worldwide, asthma affects an estimated 300 million people, and is expected to surpass 400 million by 2025, according to the World Health Organization. About 1 in 10 U.S. children have asthma, and research shows that the vast majority of them also have allergy. Could that provide a clue to its prevention?

Starting at 2 to 3 years of age, susceptible children start to become sensitized to pollens, mold spores and other airborne allergens. They begin to produce IgE antibodies, which not only trigger allergic reactions but also impair their anti-viral immune responses — potentially leading to more viral infections that can further hasten their progression to asthma.

A multicenter clinical trial, led by Wanda Phipatanakul, MD, MS, of the Division of Allergy & Immunology at Boston Children’s Hospital, now aims to test whether the anti-IgE drug omalizumab (Xolair) can short-circuit this process.
