1. What Vitaminum B 12-SF is and what it is used for
Vitaminum B 12-SF contains a vitamin from the B group, used to treat anemia.
Vitaminum B 12-SF is used in cases of vitamin B deficiency that cannot be treated with an appropriate diet.
In particular:
- in malignant Addison-Biermer anemia (a specific type of anemia resulting from a lack of vitamin B);
- in other megaloblastic anemias with a vitamin B deficiency;
- in vitamin B deficiencies due to the following reasons:
- complete exclusion of animal products from the diet (strict vegetarianism);
- inhibition (congenital or acquired) of the secretion of intrinsic factor enabling vitamin B absorption (Castle's factor);
- lack of Castle's factor due to gastric resection;
- chronic atrophic gastritis;
- malabsorption syndromes after resection of the ileum, in the course of celiac disease (a disease caused by gluten intolerance), tropical sprue (a gastrointestinal disease leading to disturbances in the absorption of nutrients), Crohn's disease (an inflammatory disease of the gastrointestinal tract);
- utilization of vitamin B by intestinal bacteria (blind loop syndrome) or parasites (infection with Diphyllobothrium latum);
- in the Schilling test (a test for vitamin B absorption).
2. Important information before using Vitaminum B 12-SF
When not to use Vitaminum B 12-SF
- if the patient is allergic to cyanocobalamin or any of the other ingredients of this medicine (listed in section 6).
Warnings and precautions
Before starting treatment with Vitaminum B 12-SF, discuss it with your doctor or pharmacist.
- In patients with Leber's disease (visual disturbances due to optic nerve atrophy), the medicine should be used with caution, as cyanocobalamin may accelerate optic nerve atrophy.
- In patients with malignant anemia, during treatment with high doses of vitamin B, the potassium level in the blood may decrease.
- In Addison-Biermer disease, vitamin B should be used regularly throughout life. A few months' break in administration, seemingly justified by good blood test results (morphology), may lead to irreversible damage to the nervous system.
- Treatment with vitamin B may reveal symptoms of erythema (severe redness of the face, hands, feet, and mucous membranes).
- Before starting treatment and between the 5th and 7th day of treatment, it is recommended to perform the following laboratory tests: folic acid level, hematocrit, reticulocytes (a significant increase in the number of reticulocytes - young red blood cells is an early sign of treatment efficacy) and vitamin B level. In the case of long-term treatment, it is recommended to monitor hematological parameters (blood condition) and vitamin B level every 3 to 6 months.
Special patient groups
Based on available data, in patients with renal, hepatic, or elderly patients, there is no need to adjust the dose.
Children and adolescents
Due to limited clinical data, it is not possible to determine the optimal dosing regimen for this medicine in children.
Vitaminum B 12-SF and other medicines
Tell your doctor or pharmacist about all medicines you are taking, have recently taken, or might take.
- Certain antibiotics, methotrexate (used to treat cancer) or pyrimethamine (used to treat malaria) may affect vitamin B levels in the serum, giving false-negative results.
- Concomitant use of medicines that suppress bone marrow function (e.g., chloramphenicol) may weaken the response to vitamin B treatment.
- Folic acid used in high doses for a long time may decrease vitamin B levels in the blood.
Due to the instability of vitamin B, mixing with other medicines may lead to loss of activity.
