Lactase supplements trigger anaphylaxis in rare case
The patient likely became sensitised from handling the supplement for his lactose-intolerant son, say doctors.
Lactose intolerance is easily managed with OTC lactase supplements, but US doctors have reported a rare case of intolerance to the supplement itself in a man who had anaphylaxis after ingestion.
The 48-year-old patient — who was a hospital-based doctor himself — had a history of mild eczema, asthma and rhinoconjunctivitis but no IgE-mediated food allergies.
