투여 방법

가능한 부작용

• Gastrointestinal effects (noted in humans with oral administration)
• Seizures (very rare, noted in humans)
• Hypersensitivity reactions (very rare, noted in humans)

주의사항 및 금기

• Known intolerance or hypersensitivity to leucovorin
• Use with extreme caution in patients receiving systemic fluorouracil. Because of its calcium content, large intravenous doses should be given slowly and not bolused. In humans, folinic acid therapy may mask the signs associated with cobalamin (B-12) deficiency in megaloblastic anemias. When reconstituting powder with bacteriostatic water (which contains benzyl alcohol), avoid use in neonates or very small animals.

약물 상호작용

• Barbiturates, Primidone, Phenytoin: Large doses of leucovorin may reduce the antiseizure efficacy of these agents.
• Fluorouracil (5-FU): Leucovorin may increase both the antineoplastic efficacy and toxicity of 5-FU.
• Trimethoprim, Ormetoprim, Pyrimethamine: Leucovorin may reduce their efficacy somewhat; however, protozoa cannot utilize leucovorin, preserving the antimicrobial effect against them.
