- What Leucovorin is and what it is used for
Leucovorin belongs to a group of drugs called antidotes. Antidotes prevent the damage caused by other substances.
Leucovorin is used to reduce the side effects of other medicines (a group of medicines called folic acid antagonists). Examples of folic acid antagonists are:
- methotrexate (a medicine often used to treat cancer)
- trimetrexate (an antibiotic and anti-cancer medicine)
- trimethoprim (an antibiotic)
pyrimethamine (a medicine often used to treat malaria) It may also be used to treat an overdose of these medicines.
Leucovorin may also be used to increase the effectiveness of the anticancer medicine fluorouracil.
2. Before you receive Leucovorin
Leucovorin must not be injected intrathecally (into the spine). Do NOT receive Leucovorin if you:
- are allergic (hypersensitive) to calcium folinate or any of the other ingredients of this medicine (see section 6)
- suffer from anaemia caused by a lack of vitamin B12 (for example pernicious anaemia).
Take special care with Leucovorin
If you are to receive Leucovorin and fluorouracil treatment at the same time take special care if:
- you have had radiotherapy
- you have stomach or bowel
Tell your doctor if the above applies to you before this medicine is used.
Special care is also needed if you are elderly and you are to receive Leucovorin and fluorouracil treatment at the same time.
Taking other medicines
Special care is needed if you are taking/using other medicines as some could interact with Leucovorin , for example:
- folic acid antagonists (see section 1 ‘What Leucovorin is and what it is used for’ for examples of these medicines) – the effectiveness of these medicines will be reduced by calcium folinate
- fluorouracil (anti-cancer medicine) – the effectiveness and side effects of this medicine will be increased by calcium folinate medicines used to treat epilepsy (phenobarbitone, phenytoin, primidone or succinimides) – the effectiveness of these medicines may be reduced by calcium folinate. Your doctor may check blood levels of these medicines and change your dose to prevent increased convulsions (fits).
Please tell your doctor or pharmacist if you are taking or have recently taken any other medicines, including any medicines obtained without a prescription.
Pregnancy and breast-feeding
If you are pregnant, planning to become pregnant or breast-feeding, ask your doctor or nurse for advice before receiving this medicine.
It is unlikely that your doctor will ask you to take/use a folic acid antagonist or fluorouracil whilst you are pregnant or breast-feeding. However, if you have taken/used a folic acid antagonist whilst pregnant or breast-feeding, this medicine (calcium folinate) may be used to reduce its side effects.
Driving and using machines
Leucovorin is not expected to affect your ability to drive or operate machinery.
Important information about some of the ingredients of Leucovorin
This medicinal product contains 0.1 mmol (or 3 mg) sodium per ml. This should be taken into consideration by patients on a controlled sodium diet.
3. How to receive Leucovorin
Leucovorin is given either into a vein (intravenously) as an injection or infusion, or into a muscle as an injection (intramuscular injection). Your medicine will be administered by a doctor or nurse.
Leucovorin 10 mg/ml Concentrate for Solution for Infusion is intended for single dose use only. Any unused solution should be discarded immediately after use.
If you are given an intravenous infusion, Leucovorin may be diluted with the recommended infusion fluids, sodium chloride or glucose solution, before administration. The sterile solution for injection should be visually inspected for clarity, particulate matter, discolouration and damage to the container before it is given to you. The solution should only be used if it is clear and the container is undamaged.
The dosage can vary from patient to patient. Your doctor will decide what dosage is best for you. Your dose and the way Leucovorin is administered will depend on the severity and type of condition you have, as well as your weight.
If you receive more Leucovorin than you should
As a doctor or nurse will be giving you your medicine, it is unlikely that you will receive an incorrect dose. Tell your doctor or nurse if you have any concerns about the amount of medicine that you receive.
If you stop receiving Leucovorin
When Leucovorin is used in combination with methotrexate and treatment is stopped abruptly, the side effects of methotrexate may re-occur. Therefore Leucovorin should not be stopped abruptly.
If you have any further questions on the use of this product, ask your doctor or nurse.
