1. What is Ferrum Lek and what is it used for
Iron is an essential component of red blood cells, muscles, and enzymes. Iron deficiency can cause chronic fatigue, lack of concentration, irritability, nervousness, headaches, loss of appetite, susceptibility to stress and infection, pallor, cracks in the corners of the mouth, dry skin, brittle hair and nails.
Ferrum Lek tablets contain ironin the form of a complex of iron(III) hydroxide with a carbohydrate polymer, polymaltose. Polymaltose protects the patient's digestive tract from the harmful effects of iron. It also inhibits the interaction of food with iron. The structure of the iron(III) hydroxide complex with polymaltose is similar to the structure of the naturally occurring iron-storing protein in the body, ferritin. Due to this similarity, iron penetrates the blood as a result of natural processes.
Ferrum Lek is used:
- to treat latent iron deficiency,
- to treat iron deficiency anemia (overt iron deficiency),
- to prevent iron deficiency during pregnancy.
2. Important information before taking Ferrum Lek
When not to take Ferrum Lek
Warnings and precautions
Before starting to take Ferrum Lek, the patient should discuss it with their doctor or pharmacist if they have anemia caused by infection or a malignant process.
Ferrum Lek and other iron preparations may cause dark discoloration of the stool. This symptom is not clinically significant.
During treatment with Ferrum Lek, tooth discoloration is possible. The discoloration should disappear on its own after the end of treatment; it can also be removed by using a toothpaste with abrasive properties or by undergoing professional tooth cleaning at the dentist.
Children and adolescents
Special caution should be exercised in children, as iron overdose can lead to poisoning.
Information for patients with diabetes
One tablet contains 0.04 WW (carbohydrate exchange units).
Ferrum Lek and other medicines
The patient should tell their doctor or pharmacist about all medicines they are currently taking or have recently taken, as well as any medicines they plan to take.
No interactions have been described so far. Due to the fact that the iron in Ferrum Lek is bound in a complex, interactions with food components (e.g., oxalates [found in vegetables], tannin [found in tea], vitamins A, D, and E, and soy) or concomitantly taken medicines (e.g., antibiotics from the tetracycline group, antacids) are unlikely.
Iron treatment does not affect the result of the occult blood test, so if the doctor has prescribed such a test, it is not necessary to discontinue Ferrum Lek.
It is not recommended to take iron in other forms (e.g., injections or tablets) at the same time. The patient should inform their doctor if they are taking any other iron-containing medicine.
Pregnancy and breastfeeding
If the patient is pregnant or breastfeeding, thinks they may be pregnant, or plans to have a child, they should consult their doctor or pharmacist before taking this medicine.
Pregnancy
There are no available data on the use of the medicine in the first trimester of pregnancy. No serious side effects have been reported after taking Ferrum Lek syrup in therapeutic doses for the treatment of anemia during pregnancy. Animal studies have not shown any risk to the fetus and mother.
Breastfeeding
Iron penetrates into breast milk, where it occurs in the form of lactoferrin. Only a small amount of iron from the iron(III) hydroxide complex with polymaltose penetrates into breast milk.
The risk to the breastfed child is small.
Ferrum Lek can be used during pregnancy and breastfeeding only on the doctor's recommendation.
Driving and using machines
No relevant studies have been conducted, but it is unlikely that Ferrum Lek tablets will affect the ability to drive and use machines.
Ferrum Lek contains aspartame
The medicine contains 1.5 mg of aspartame (E 951) per tablet. Aspartame is a source of phenylalanine. It may be harmful to patients with phenylketonuria. This is a rare genetic disorder in which phenylalanine accumulates in the body due to improper excretion.
