1. What is Calcium Folinate Kalceks and what is it used for

Calcium Folinate Kalceks 10 mg/ml Solution for Injection and Infusion contains the active substance folinic acid, as calcium folinate hydrate (hereinafter referred to as calcium folinate). Calcium folinate is the calcium salt of folinic acid. This belongs to a group of medicines called 'antidotes'.

This medicine is used to:

• reduce the harmful effects and treat overdose of certain cancer medicines, such as methotrexate and other folinic acid antagonists in adults and children. This process is known as "calcium folinate rescue";
• treat cancer in combination with fluorouracil (a cancer medicine). Fluorouracil works better when given with calcium folinate.

2. What you need to know before you are given Calcium Folinate Kalceks

Do not useCalcium Folinate Kalceks

• if you are allergic to calcium folinate or any of the other ingredients of this medicine (listed in section 6);
• if you have a type of anemia (low red blood cell count) caused by a lack of vitamin B12.

If you are not sure if any of the above applies to you, consult your doctor or nurse before you are given this medicine.

If you are pregnant or breastfeeding, you should not receive Calcium Folinate Kalceks with certain cancer medicines (your doctor will know which ones).

This medicine must not be injected into the spine (by intrathecal route).

Warnings and precautions

Tell your doctor or nurse before you are given this medicine if:

• you have kidney problems (you may need to take a higher dose or need this medicine for a longer period);
• you have epilepsy.

Use of calcium folinate with fluorouracil

You must not receive this medicine with fluorouracil if you have noticed that your medicine causes stomach and intestine problems.

If you are to receive calcium folinate with fluorouracil at the same time, consult your doctor or nurse before you are given this medicine if:

• you have received radiotherapy;
• you have stomach or intestine problems;
• you have inflammation inside your mouth;
• you are elderly;
• you feel very weak.

Your doctor will monitor your liver and/or kidney function and will do regular blood tests to check this.

Other medicines and Calcium Folinate Kalceks

Tell your doctor or nurse if you are using, have recently used or might use any other medicines.

This is especially important if you are using any of the following medicines, as special care may be needed:

• medicines known as folinic acid antagonists, such as cotrimoxazole (an antibiotic) or pyrimethamine (used to treat malaria). Calcium folinate may reduce or completely counteract the effect of these medicines;
• fluorouracil(a cancer medicine). Calcium folinate increases the effectiveness and also the side effects of fluorouracil;
• medicines for treating epilepsy(phenobarbital, phenytoin, primidone or succinimides, for example, ethosuximide). Calcium folinate may decrease the effect of these medicines. Your doctor may check the levels of these medicines in your blood and change your dose to avoid an increase in seizures (epileptic fits).

Pregnancy and breastfeeding

If you are pregnant or breastfeeding, think you may be pregnant or are planning to have a baby, ask your doctor for advice before you are given this medicine.

Calcium folinate is not harmful if used alone during pregnancy.

You must not receive Calcium Folinate Kalceks with fluorouracil during pregnancy or breastfeeding, as it may harm your baby.

Calcium folinate will only be given with methotrexate during pregnancy or breastfeeding if your doctor thinks it is necessary.

Driving and using machines

There is no evidence that calcium folinate affects your ability to drive or use machines.

Calcium Folinate Kalceks contains sodium

3. How to use Calcium Folinate Kalceks

This medicine can be given as an injection or infusion (drip) into a vein or as an injection into a muscle. If given by infusion, it must first be diluted.

Your doctor will decide the correct dose of this medicine for you and how often you should receive it. The decision will depend on the health problem being treated, your body surface area and any other treatment you may be receiving.

Tell your doctor or nurse immediatelyif you experience:

• a sudden rash with itching (urticaria), swelling of hands, feet, ankles, face, lips, mouth or throat (which may cause difficulty in swallowing or breathing), and feeling like you are going to faint. These can be signs of a very rare and serious allergic reaction (may affect up to 1 in 10,000 people). You may need urgent medical attention
• red patches on the body, target-like or circular patches on the trunk, often with blisters in the center, peeling of the skin, ulcers in the mouth, throat, nose, genitals and eyes. These severe skin reactions may be preceded by fever and flu-like symptoms (Stevens-Johnson syndrome, toxic epidermal necrolysis) (frequency cannot be estimated from the available data)

Uncommon(may affect up to 1 in 100 people)

• fever

Rare(may affect up to 1 in 1,000 people)

• insomnia
• agitation and depression (after high doses)
• increased seizures (fits) in patients with epilepsy
• gastrointestinal disorders (after high doses)

Only with combination treatment with fluorouracil

If you receive calcium folinate in combination with fluorouracil, you are more likely to experience the following side effects:

Very common(may affect more than 1 in 10 people)

• bone marrow failure (even life-threatening)
• inflammation of the lining of the intestine and mouth (potentially life-threatening diseases have occurred)
• nausea, vomiting and diarrhea (with monthly doses)
• severe diarrhea and dehydration (with weekly doses)

Common(may affect up to 1 in 10 people)

• redness and swelling of the palms of the hands or soles of the feet, which can cause skin peeling (palmar-plantar erythrodysesthesia or 'hand-foot syndrome')

Frequency not known(frequency cannot be estimated from the available data)

• high levels of ammonia in the blood

Tell your doctor if you experience diarrhea or mouth ulcers, as your doctor may consider reducing the dose of fluorouracil until the symptoms have completely disappeared.

As diarrhea can be a sign of stomach and intestine toxicity, if you have these symptoms, you will be closely monitored until the symptoms have completely disappeared. These symptoms can be the start of a rapid deterioration leading to death.

Your doctor may do tests to check if you have low calcium levels in your blood.

This information is intended only for healthcare professionals:

Incompatibilities

This medicine must not be mixed with other medicines except for those mentioned in the "Instructions for use, disposal and other handling" section below.

Incompatibilities have been reported between injectable forms of calcium folinate and injectable forms of droperidol, fluorouracil, foscarnet and methotrexate.

Droperidol

• Droperidol 1.25 mg/0.5 ml with calcium folinate 5 mg/0.5 ml, immediate precipitation after direct mixing in a syringe for 5 minutes at 25°C followed by 8 minutes of centrifugation.
• Droperidol 2.5 mg/0.5 ml with calcium folinate 10 mg/0.5 ml, immediate precipitation when the medicines are injected sequentially into a Y-shaped equipment without flushing the Y-shaped equipment between injections.

Fluorouracil

Calcium folinate must not be mixed in the same infusion as fluorouracil because a precipitate may form. 50 mg/ml of fluorouracil with 20 mg/ml of calcium folinate, with or without glucose 5% injection solution (50 mg/ml), have been shown to be incompatible when mixed in different amounts and stored at 4°C, 23°C or 32°C in polyvinyl chloride containers.

Foscarnet

A yellowish turbid solution has been observed when mixing 24 mg/ml of foscarnet with 20 mg/ml of calcium folinate.

Instructions for use, disposal and other handling

For single use only.

The solution should be used immediately after opening the vial. Discard any remaining contents after use.
