1. What is Tardyferon and what is it used for
The need for iron is increased in women during pregnancy, postpartum, breastfeeding, and in adolescents during growth. Iron deficiency or iron deficiency anemia can be prevented or treated with Tardyferon.
In combination with iron and auxiliary substances, Fe ions are released slowly, which allows avoiding the sudden absorption of the entire iron dose into the blood serum.
This reduces the number of observed side effects and makes it easier for the patient to follow the recommendations. The slow release of the medicine allows iron ions to reach the final sections of the intestine, which, in addition to the duodenum, have the ability to absorb iron. The limitation of iron absorption to the upper segments of the intestine is caused by the iron saturation process. Like all iron-containing medicines, Tardyferon has no effect on erythropoiesis (red blood cell production) or anemia caused by factors other than iron deficiency.
Tardyferon is used to treat iron deficiency anemia and prevent iron deficiency in pregnant women with insufficient dietary intake.
Tardyferon is indicated for use in children over 10 years old and adults.
2. Important information before taking Tardyferon
When not to take Tardyferon
Warnings and precautions
Before starting to take Tardyferon, discuss it with your doctor or pharmacist.
The toxic dose of iron is lower for children than for adults. It is not recommended to give Tardyferon to children under 10 years old.
Iron deficiency supplementation should be, if possible, combined with treatment of the cause of the deficiency.
If the tablet gets into the airways, patients, especially the elderly and those with swallowing difficulties, may also be at risk of throat ulcers, esophageal ulcers, or bronchial ulcers. Bronchial necrosis (tissue death) or granuloma (inflammation) can lead to bronchial stenosis (narrowing of the airways). In case of improper swallowing, you should immediately contact a doctor or the nearest emergency department for proper treatment.
In medical literature, in elderly patients with chronic kidney disease, diabetes (high blood sugar), and (or) hypertension (high blood pressure) treated with several medications for these diseases and receiving iron supplementation due to accompanying anemia, gastrointestinal melanosis (discoloration of the gastrointestinal tract) has been described.
Children and adolescents
Tardyferon can be used in children over 10 years old.
Tardyferon and other medicines
Do not take Tardyferon unless your doctor decides to.
Some medicines cannot be taken at the same time, while others require special changes (e.g., time of administration):
It is recommended to avoid taking Tardyferon if the patient is taking iron-containing injections.
The following medicines may require a dose adjustment. Do not take Tardyferon within 2 hours of taking any of the following medicines:
- certain antibiotics (tetracyclines or fluoroquinolones);
- medicines used to treat weak bones (bisphosphonates);
- a medicine used to treat joint diseases (penicillamine);
- medicines used to treat excess stomach acid: mineral preparations acting on the gastrointestinal tract, charcoal, or antacids (aluminum, calcium, and magnesium salts);
- a medicine used to treat thyroid disease (thyroxine);
- a medicine used to treat Parkinson's disease (methyldopa, levodopa, carbidopa;
- supplements and (or) medicines containing zinc or calcium;
- cholestyramine - Tardyferon should be taken 1-2 hours before or 4 to 6 hours after cholestyramine;
- NSAIDs (nonsteroidal anti-inflammatory drugs) - they should be taken with food to reduce irritation of the stomach and intestinal mucosa and lower the risk of bleeding associated with their use.
If the patient is currently taking or has recently taken another medicine that is available without a prescription, they should tell their doctor or pharmacist.
Tardyferon with food, drink, and alcohol
Consuming large amounts of coffee, tea, or red wine may reduce iron absorption. It is not recommended to take this medicine at the same time as whole grain products (bran, legumes, oilseeds), some proteins (eggs), or foods and drinks containing calcium (cheese, milk, etc.). There should be a gap between taking iron salts and these foods (at least 2 hours).
Pregnancy, breastfeeding, and fertility
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.
Tardyferon can be used during pregnancy and breastfeeding.

Taking a higher dose of Tardyferon than recommended
Cases of iron salt overdose have been reported, especially in children due to swallowing a large amount of medicine.
Symptoms of overdose include signs of gastrointestinal irritation with accompanying abdominal pain, nausea, vomiting, diarrhea, symptoms of cardiovascular shock or metabolic acidosis (rapid or shallow breathing, rapid heartbeat, headache, confusion, drowsiness, fatigue, loss of appetite), and liver and kidney failure.
If you have taken too much medicine, you should immediately contact the emergency department for proper treatment.
