IMFINZI Warnings/Precautions:

Severe and fatal immune-mediated adverse reactions can develop. Monitor closely for immune-related pneumonitis, colitis, hepatitis, endocrinopathies (adrenal insufficiency, thyroid disorders, hypophysitis/hypopituitarism, diabetes), nephritis/renal dysfunction, dermatologic reactions, myocarditis, neurological toxicities, others. Withhold or permanently discontinue based on severity and type of adverse reaction; see full labeling for management guidelines. Obtain liver enzymes, creatinine, and thyroid function at baseline and periodically during therapy. Monitor for infection. Evaluate for Vogt-Koyanagi-Harada-like syndrome if uveitis in combination with other immune-mediated reactions occur. Interrupt, slow the infusion rate, or permanently discontinue based on severity of infusion-related reactions. Monitor closely for allogeneic HSCT-related complications (eg, graft-versus-host-disease, hepatic veno-occlusive disease, steroid-requiring febrile syndrome) and manage promptly. Embryo-fetal toxicity. Advise females of reproductive potential to use effective contraception during and for ≥3 months after the last dose. Pregnancy.
