Antibiotics in babies linked to eczema

The systematic review and meta-analysis of observational studies involving participants aged 0—25 years assessed the impact of antibiotic exposure in utero and in the first 12 months on subsequent eczema risk.

It found exposure in the first year of life may increase susceptibility to eczema by up to 40%, with broad spectrum antibiotics having a more pronounced effect.

Each additional course of antibiotics in the first year conferred a further 7% increased risk.
