Prenatal opioid exposure is associated with an increased risk for infection, eczema and dermatitis, and asthma in offspring, but not allergies or anaphylaxis, according to an Australian study in JAMA Network Open.

University of WA researchers compared the risk for hospitalisation and ED presentation for immune-related conditions in children with and without prenatal opioid exposure using linked administrative health records for all 401,462 children born between 2003 and 2018.
