What DBL™ Leucovorin Calcium is used for
DBL™ Leucovorin Calcium is considered to be a supportive therapy. It is used in two main situations:
- When your body does not have enough folic acid.
This occurs in conditions such as megaloblastic anaemia, where the level of red blood cells and iron in the blood is too low. Megaloblastic anaemia can happen during pregnancy or infancy, or due to liver disease, malnutrition, or a reduced ability to absorb folic acid from the diet.
- As an antidote or rescue therapy to the toxic effects of some medications such as methotrexate.
DBL™ Leucovorin calcium is not addictive.
