1. What is Calcium Folinate Kalceks and What is It Used For

Calcium Folinate Kalceks, 10 mg/mL, Solution for Injection/Infusion contains the active substance calcium folinate, which is the calcium salt of folinic acid (also known as leucovorin). Folinic acid is an antidote used to treat or prevent low blood cell counts caused by certain chemotherapy drugs, such as methotrexate. This medicine is used to:

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

2. Before You Use Calcium Folinate Kalceks

Do Not Use Calcium Folinate Kalceks:

• if you are allergic to folinic acid or any of the other ingredients of this medicine (listed in section 6);
• if you have a certain type of anemia (low red blood cell count) caused by a lack of vitamin B12. If you are unsure whether any of the above conditions apply to you, consult your doctor or nurse before using this medicine.

Calcium Folinate Kalceks should not be used with certain chemotherapy drugs (known to your doctor) in pregnant or breastfeeding women. This medicine must not be administered directly into the spine (intrathecally).

Warnings and Precautions

Before Using Calcium Folinate Kalceks, Tell Your Doctor or Nurse If:

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

Using Folinic Acid with Fluorouracil Do not use this medicine with fluorouracil if it causes stomach or intestinal problems. If you need to use folinic acid and fluorouracil together, talk to your doctor or nurse before using this medicine if:

Calcium Folinate Kalceks and Other Medicines

Tell Your Doctor or Nurse About All Medicines You Are Taking or Have Recently Taken, as Well as Any Medicines You Plan to Take. This is Especially Important for the Following Medicines:

• medicines known as folate antagonists, such as trimethoprim/sulfamethoxazole (an antibiotic) or pyrimethamine (used to treat malaria). Folinic acid may reduce or completely counteract the effects of these medicines;
• fluorouracil(a chemotherapy drug). Folinic acid increases the effectiveness and side effects of fluorouracil;
• medicines used to treat epilepsy(phenobarbital, phenytoin, primidone, or succinimides, such as ethosuximide). Folinic acid may reduce the effects of these medicines. Your doctor may check the levels of these medicines in your blood and adjust the dose to prevent increased seizures.
