Steroid Allergy: Clinical Features and the Importance of Excipient Testing in a Diagnostic Algorithm

ConclusionsPatients with respiratory manifestations were significantly more likely to be truly allergic. CS allergies are rare and may be overdiagnosed without excipient testing. We suggest the use of Carmellose eye drops as a readily available source of carboxymethylcellulose for testing and propose a comprehensive diagnostic algorithm for suspected CS allergy.
