Feedback:
A drug such as leucovorin, often called leucovorin rescue, may be administered after systemic methotrexate to neutralize its action and protect normal cells from the effect of the drug. Leucovorin is not used to encourage the growth of new cells in the bone marrow. It does not facilitate the use of methotrexate in the cells. Leucovorin is not an experimental drug used to improve resistance to infection.
