Critical safety information and handling instructions for clinicians.

Important Warnings

Elitek is contraindicated in patients with G6PD deficiency due to risks of severe hemolysis and methemoglobinemia. Pre-treatment screening for G6PD deficiency is recommended in high-risk populations. Serious hypersensitivity reactions, including anaphylaxis, can occur. Blood samples for uric acid measurement require special handling: collection in pre-chilled heparinized tubes, immediate immersion in an ice-water bath, and plasma assay within 4 hours to prevent ex vivo degradation.
