Important Safety Information for Khapzory

Contraindications

  • Khapzory is contraindicated in patients who have had severe hypersensitivity to leucovorin products, folic acid, or folinic acid.

Warnings and Precautions

  • Increased gastrointestinal toxicities with fluorouracil: Gastrointestinal toxicities, including stomatitis and diarrhea, occur more commonly and may be of greater severity and of prolonged duration. Deaths from severe enterocolitis, diarrhea, and dehydration have occurred in elderly patients receiving weekly d,l-leucovorin and fluorouracil. Do not initiate or continue therapy with Khapzory and fluorouracil in patients with symptoms of gastrointestinal toxicity until those symptoms have resolved. Monitor patients with diarrhea until it has resolved as rapid deterioration leading to death can occur.
  • Drug interaction with trimethoprim-sulfamethoxazole: Concomitant use of d,l-leucovorin with trimethoprim-sulfamethoxazole for the acute treatment of Pneumocystis jiroveci pneumonia in patients with HIV infection increased treatment failure and morbidity.

Adverse Reactions

  • The most common adverse reactions (≥20%) in patients receiving high-dose methotrexate therapy with levoleucovorin rescue were stomatitis (38%) and vomiting (38%).
  • The most common adverse reactions (>50%) in patients receiving levoleucovorin in combination with fluorouracil for metastatic colorectal cancer were stomatitis (72%), diarrhea (70%), and nausea (62%).

Drug Interactions
Leucovorin products increase the toxicity of fluorouracil.

Use in Specific Populations
Levoleucovorin is administered in combination with methotrexate or fluorouracil, which can cause embryo-fetal harm. Refer to methotrexate and fluorouracil prescribing information for additional information.
