Does Pegvaliase Pqpz Interact with Medroxyprogesterone Acetate Suspension?
CDI records a major classification for Pegvaliase Pqpz and Medroxyprogesterone Acetate Suspension. The stored summary is: Concomitant use may cause hypersensitivity reactions including anaphylaxis. Two patients experienced hypersensitivity reactions within 10-15 minutes of medroxyprogesterone acetate injection after PEGVALIASE-PQPZ dosing, with one progressing to anaphylaxis. The mechanism involves anti-peg igg antibody formation from pegvaliase-pqpz may cross-react with peg-containing formulations like medroxyprogesterone acetate suspension (peg 3350). Patients taking both medications should consult their healthcare provider before starting, stopping, or changing the dosage of either drug. This record was extracted from drug labeling through openFDA. NIH/NLM RxNorm is used for drug identities.
