CALCIFOLIN
ItalyIt is used as an antidote for excessive doses of folic acid antagonists and to counteract side effects caused by aminopterin and methotrexate. It is also indicated for all forms of anemia caused by folate deficiency (due to increased demand, reduced utilization, or insufficient dietary intake).
Frequently asked questions
How should Calcifolin be taken?
For the treatment of folate deficiency anemias, the dose is 15-25 mg per day for a period of 10-15 days. To prevent toxic effects from methotrexate, the average dose is 50 mg every 6 hours for 3 consecutive days, starting 24 hours after the methotrexate infusion.
When should you not take this medicine?
It must not be used in case of hypersensitivity to any of the components. It must not be administered to treat pernicious anemia or other megaloblastic anemias involving a vitamin B deficiency, unless it is taken together with vitamin B itself.
What are the possible side effects of Calcifolin?
Although very rarely, administration may cause general hypersensitivity reactions.
Are there any special precautions to follow?
In case of overdose of folic acid antagonists, administration should ideally occur within 1 hour; after 4 hours, it is generally ineffective. If used for anemias related to vitamin B deficiency, the drug must be combined with vitamin B therapy, and treatment must be monitored by medical personnel experienced in hematology and neurology.
Does the drug interact with other medicines?
The folinic acid contained in the product acts as a 'rescue' during high-dose methotrexate therapy and serves as an antidote in case of overdose of folic acid antagonists.

THERAPEUTIC INDICATIONS
Calcifolin is useful as an antidote to excessive doses of folic acid antagonists and to counteract the side effects induced by aminopterin and methotrexate. Calcifolin is also indicated in all forms of anaemia due to folate deficiency caused by increased demand, reduced utilization, or inadequate dietary intake of folates.
CONTRAINDICATIONS
Hypersensitivity to any of the components.
CALCIFOLIN must not be administered for the treatment of pernicious anaemia or other megaloblastic anaemias when vitamin B({12}) is deficient, unless used in combination with vitamin B({12}).
PRECAUTIONS FOR USE
Calcifolin, when administered in pernicious anaemia or in other megaloblastic anaemias due to vitamin B({12}) deficiency, may induce haematological remission while leaving the progression of neurological lesions unchanged (see also contraindications). In such cases, the product should be associated with appropriate vitamin B({12}) therapy, and treatment must be carried out under haematological and neurological monitoring. Anaemias during pregnancy due to increased folate requirements may be improved or normalized by administration of folinic acid.
In the treatment of overdose with folic acid antagonists, Calcifolin should be administered preferably within 1 hour, as administration beyond 4 hours is generally ineffective. The drug should be administered carefully to avoid the risk of allergic reactions or adverse effects.
INTERACTIONS WITH OTHER MEDICINES AND OTHER KINDS OF INTERACTIONS
Folinic acid antagonizes the effects of antifolates. It acts as a "rescue" agent in high-dose methotrexate therapy and as an antidote in cases of overdose.
SPECIAL WARNINGS
Keep the medicine out of the reach of children.
