AIM: The main objective of this study was to see how many of the children, with a suspected antibiotic allergy, developed an allergic or adverse reaction to a drug provocation test.
METHODS: Data on children that had undergone a drug provocation test for a suspected antibiotic allergy were compiled retrospectively for the period from 2007-2018. The median age at the first provocation was 2.25 years (1.5-5.7). Standardised questionnaires, the children's parents had answered before the provocation, were used to evaluate the originally suspected allergic reaction, previous health, atopic diseases and family history.
RESULTS: Ninety-two (6.4%) of the 1440 children showed a possible mild allergic reaction. Sixty-four of the 92 children underwent a second drug provocation test 1-2 years later. At that time, only eleven developed a positive- or a possible-delayed reaction.
CONCLUSION: An immediate moderate or severe allergic reaction was excluded in all cases of suspected antibiotic allergy in this study. Our study indicates that an oral drug provocation test is safe. It may be appropriate to wait for 6 months or more after the initial event of ADR before these tests are performed. A second oral provocation 1-2 years after the first one shows that ADRs are outgrown in most children.
