Coexistence of two types of allergic hypersensitivity to drugs: case report

Hypersensitivity to drugs is a complex diagnostic challenge. Detailed medical history remains the mainstay of drug hypersensitivity evaluation, which further determines diagnostic procedures, especially the types of skin tests to be performed. The current paper presents the case of a female patient with coexisting features of supposed immunoglobulin E (IgE) dependent allergic hypersensitivity to fluoroquinolones and those of non‑IgE dependent allergic hypersensitivity to povidone‑iodine. Hypersensitivity was diagnosed based on the appropriately selected skin tests.
