Calcium Folinate
About Calcium Folinate
Calcium Folinate is a prescription injection used to reduce the harmful side effects of specific cancer therapies, such as high-dose methotrexate. It is also used to increase the clinical effectiveness of other chemotherapy medications in treating advanced colon cancer, and to treat severe types of anaemia caused by vitamin deficiency.
Since this medicine is given as an injection or infusion into a vein or muscle, it is administered on a strict schedule by a healthcare professional in a hospital or clinic. To support your body during this treatment, eating a balanced diet rich in proteins and staying highly hydrated can significantly improve your recovery.
While receiving this injection, you may experience mild side effects like nausea, diarrhoea, or temporary skin flushing. However, if you develop serious signs such as a severe skin rash, itching, or sudden breathing difficulties, you must tell your doctor or nurse immediately.
Before starting your therapy, tell your doctor if you have a history of seizures, kidney disease, or severe dehydration. You must not receive this injection if you have a known severe allergy to it, or if you have certain types of anaemia, such as pernicious anaemia, that are not caused by folate deficiency.
This medicine can interact with alcohol, smoking, and certain epilepsy medications, which may reduce the seizure medication's effectiveness and increase your risk of fits. If you are pregnant, planning to become pregnant, breastfeeding, or are an elderly patient, consult your doctor or pharmacist to discuss your specific safety plan.
Uses of Calcium Folinate
Medicinal Benefits
Calcium Folinate provides reliable support to help protect healthy tissues and manage the physical toll of intensive therapies. By supporting your body during treatment, this medicine brings several key health benefits:
- Minimises therapy complications: By acting as a protective shield for healthy tissues, it helps prevent painful mouth sores, severe gut issues, and bone marrow suppression (a condition where your body cannot make enough healthy blood cells). This allows you to complete your scheduled cancer therapy with fewer painful interruptions.
- Boosts treatment success: When used alongside colon cancer treatments, it helps improve the overall effectiveness of your therapy, supporting your body's fight against the disease.
- Restores energy and strength: For patients with severe vitamin deficiencies, it directly aids the production of healthy blood cells, which helps relieve extreme fatigue, weakness, and shortness of breath.
Directions for Use
- Follow your doctor's instructions on the dosage and timing of this medication to ensure safety.

Medicines Containing this Salt
View AllDrug Warnings
- Never give into the spinal fluid: Calcium Folinate is strictly for intravenous (IV, into a vein) or intramuscular (IM, into a muscle) use only. It must never be injected into the spinal fluid (intrathecally), as this can cause severe or fatal nervous system damage.
- Verify the solution: Always inspect the liquid before injection; it should be clear and pale yellow. Do not use it if it contains particles or is cloudy.
- Follow safety disposal protocols: If administering at home under supervision, use a puncture-proof sharps container to safely discard all needles and syringes.
- Report kidney changes: Inform your doctor immediately if you experience a decrease in urination, as poor kidney function can slow down how fast your body clears chemotherapy.
- Avoid immediate driving: Some patients may feel dizzy or tired after receiving this injection; avoid driving until you know how it affects you.
- Do not mix in the same line: Ensure your healthcare provider does not mix Calcium Folinate in the exact same IV line with certain other drugs, like 5-fluorouracil, at the same time unless clinically managed, as the medicines can clump together and block the IV line.
Drug Interactions
- Seizure medications: May decrease the effectiveness of medicines like phenytoin, fosphenytoin, phenobarbital, and primidone, increasing the risk of seizures.
- Chemotherapy drugs: Can increase the toxicity of 5-fluorouracil, which must be carefully monitored by your medical team.
- Folate-blocking antibiotics (antifolates): Medicines that block folate, such as trimethoprim or sulfamethoxazole, may interfere with the action of this medication if taken at the same time.

Habit Forming
Diet & Lifestyle Advise
- Stay well-hydrated: Drink plenty of fluids (as advised by your doctor) to help your kidneys flush out chemotherapy medications efficiently.
- Eat small, frequent meals: If you experience nausea or mouth sores from your cancer therapy, eating soft, bland foods can help maintain your nutrition.
- Avoid self-supplementing: Do not take over-the-counter folic acid or multivitamin supplements containing folic acid unless specifically directed by your doctor. Self-supplementing can interfere with your chemotherapy and can also mask underlying vitamin B12 deficiency (pernicious anaemia) while neurological damage continues.
- Monitor your temperature: Keep a thermometer at home and check your temperature regularly, reporting any signs of fever or infection to your oncologist immediately.

FAQs
Calcium Folinate is used to prevent the harmful effects of methotrexate.
Calcium Folinate contains calcium folinate, also known as Leucovorin. This compound prevents healthy cells from the toxic effects of methotrexate (cancer medicine) while accepting it to enter and kill cancer cells.
It is contraindicated to use if you are known for hypersensitivity to any components present in Calcium Folinate or if you have Pernicious anaemia or other anaemias due to vitamin B12 deficiency.
Megaloblastic anemia is a condition where abnormal, oversized red blood cells form due to defective DNA production, typically from a lack of vitamin B12 or folate (folic acid). Symptoms include fatigue, pale skin, and sometimes neurological issues.
Your doctor may recommend specific blood tests during your treatment with Calcium Folinate to check methotrexate levels especially if you are undergoing chemotherapy or in cases of overdose. A complete blood count (CBC) will also be done to check red blood cell levels if you are being treated for anemia and also calcium levels (to avoid hypercalcemia due to calcium in Calcium Folinate). These tests are essential for ensuring the treatment is both safe and effective.
To promote the excretion of methotrexate during treatment with Calcium Folinate, increase fluid intake to maintain urine output above 2,500 mL/day for 12 hours before and 36 hours after methotrexate infusion. Ensure urine pH is above 7.0 before the infusion and avoid acidic substances. Measure blood methotrexate levels at 24, 48 and 72 hours after infusion.
No, Calcium Folinate is not a chemotherapy drug. It is a supportive care medicine (an active form of folate) used to protect healthy cells from chemotherapy toxicity or to make certain cancer treatments work better. Talk to your doctor for more details about your specific treatment plan.
This medicine is generally only used during pregnancy if your doctor determines the benefits outweigh the risks. If you are pregnant or planning to become pregnant, talk to your doctor or pharmacist before starting therapy.
It is given as an injection into a muscle (intramuscularly) or as an infusion directly into a vein (intravenously) by a trained healthcare professional. Talk to your doctor if you have questions about your administration route.
Regular folic acid must be converted by an enzyme in the body into an active form, which chemotherapy drugs can block. Calcium Folinate is already in the active form, so it can bypass this block and protect your cells immediately. Talk to your doctor or pharmacist to learn more.
The timing is critical because it must be given at precise intervals relative to your chemotherapy (such as methotrexate) to rescue healthy cells before they suffer permanent damage. Talk to your doctor to understand your schedule.
Calcium Folinate itself does not typically cause hair loss. However, it is often given alongside chemotherapy drugs that do cause hair loss. Talk to your doctor if you are concerned about side effects from your treatment regimen.
It is highly recommended to avoid alcohol while undergoing cancer treatment or receiving Calcium Folinate, as alcohol can worsen liver strain and dehydration. Talk to your doctor or pharmacist for personalised advice.
Yes, if you are storing this medicine at home before your clinic appointment, it must be kept in a refrigerator between 2°C and 8°C (36°F to 46°F) and protected from light. Talk to your doctor or pharmacist if you have storage concerns.
