用途
作用方式
Leucovorin is a mixture of diastereoisomers of 5-formyl tetrahydrofolic acid. It does not require reduction by dihydrofolate reductase to take part in folate one-carbon reactions, so it counteracts the therapeutic and toxic effects of folic acid antagonists such as methotrexate.
成人常用劑量（仿單摘要）
Rescue after high-dose methotrexate (normal elimination): 15 mg IV or IM every 6 hours for 60 hours (10 doses total), starting 24 hours after the start of methotrexate infusion
懷孕與哺乳

- Safe Leucovorin (folinic acid) is a form of folate; no animal studies, and the US label says use only if clearly needed. Folate itself is not harmful in pregnancy. It is usually given with methotrexate or fluorouracil, which can harm the fetus: follow the partner drug's advice.
- 哺乳
- Safe Folinic acid and its forms are normal components of breast milk. Alone it is not expected to harm the infant (US label: use caution). When given with methotrexate or fluorouracil, the partner drug decides: breastfeeding is usually stopped during chemotherapy.
