Pegaspargase 3750 IU Injection (5 ml) is a prescription oncology medicine used in the treatment of acute lymphoblastic leukemia (ALL). It contains pegylated L‑asparaginase, an enzyme that deprives leukemia cells of asparagine — a nutrient they need to survive. The pegylation process increases drug stability and reduces the frequency of dosing compared with older asparaginase forms, making treatment more convenient and better tolerated. Pegaspargase is administered by intravenous infusion or intramuscular injection under the supervision of trained oncology professionals, with regular monitoring for liver, pancreas, and blood function throughout therapy. Pricing varies significantly due to import costs and pharmacy sourcing; valid doctor’s prescription required
