It is used in the treatment of megaloblastic anaemia (the presence of large, immature, and dysfunctional red blood cells (megaloblasts) in the bone marrow). It is also used to enhance the effectiveness of 5-fluorouracil in the treatment of certain cancers, by increasing the efficacy of the drug while reducing its toxicity.

Additionally it also helps to protect healthy cells by “rescuing” them from the toxic effects of the chemotherapy drug.
