Abstract

Background: Some foods and drug additives may induce allergic reactions.

Case report: A girl with a family history of asthma in both parents developed asthma in her early life. She was successfully given continuous bronchodilator therapy until the age of 7 years. At that time, she had more frequent and severe exacerbations (8 within 10 months) despite reinforced continuous treatment. Oral challenges with bisulfite and sodium benzoate, both additives abundantly ingested by the patient, revealed heightened sensitivity to administration of sodium benzoate. Avoidance of this additive was followed by complete and prolonged disappearance of episodes of coughing and wheezing.

Conclusion: Adverse reactions to benzoate in this patient required avoidance of some drugs, some of those classically prescribed under the form of syrups in asthma.
