Steroid allergy: Clinical features and the importance of excipient testing in a diagnostic algorithm

Conclusion Patients with respiratory manifestations were significantly more likely to be truly allergic. CS allergies are rare and may be over-diagnosed 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.
