What the FDA labels say about taking them together
Hydrogen peroxide and rasburicase
Rasburicase's FDA label of July 30, 2026 names hydrogen peroxide in its warnings and precautions section; the hydrogen peroxide label PlainMeds reads does not name rasburicase. The rasburicase label: “Elitek is contraindicated in patients with G6PD deficiency because hydrogen peroxide is one of the major by-products of the conversion of uric acid to allantoin.”
