What special consideration is required before using rasburicase in TLS?

Rasburicase rapidly lowers uric acid levels, which is crucial in tumor lysis syndrome when there’s a high risk or significant uric acid elevation. A key precaution is screening for G6PD deficiency before giving rasburicase, because the drug can cause oxidative stress leading to acute hemolysis in G6PD-deficient individuals. If G6PD deficiency is present, rasburicase should be avoided and alternative management chosen. So, the best approach combines using rasburicase for high-risk TLS or significant hyperuricemia with performing G6PD deficiency screening prior to use.
