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 a drug called 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 drug 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 drugs, 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 to 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
- if the patient is allergic to iron sulfate or any of the other ingredients of this drug (listed in section 6);
- if there is an excess of iron, e.g., hemochromatosis, thalassemia, anemia resistant to treatment, or bone marrow failure.
Warnings and precautions
Before starting to take Tardyferon, you should discuss it with your doctor or pharmacist.
A 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 this deficiency.
If the tablet gets into the airways, patients, especially the elderly and those with difficulty swallowing, may also be at risk of throat ulcers, esophagus (connecting the mouth to the stomach), or bronchi (main airways leading to the lungs). Bronchial necrosis (tissue death) or granuloma (inflammatory condition) can lead to bronchial narrowing (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 levels), and (or) hypertension (high blood pressure) treated with several drugs for these diseases and receiving iron supplementation due to accompanying anemia, gastrointestinal melanosis (discoloration in the gastrointestinal tract) has been described.
Due to the risk of oral ulcers and tooth discoloration, tablets should not be sucked, chewed, or held in the mouth, but swallowed whole, with water. If following these instructions is not possible or there are difficulties with swallowing, you should contact your doctor.
Children and adolescents
Tardyferon can be used in children over 10 years old.
Tardyferon and other drugs
Tardyferon should not be taken if the doctor has not decided on it.
Some drugs cannot be taken at the same time, while others require special changes (e.g., time of administration).
It is not recommended to take Tardyferon if the patient is taking iron-containing drugs for injection.
The following drugs may require a dose adjustment. Tardyferon should not be taken within 2 hours of taking any of the following drugs:
- certain antibiotics (tetracyclines or fluoroquinolones);
- drugs used to treat weakened bones (bisphosphonates);
- a drug used to treat joint diseases (penicillamine);
- drugs used to treat excess stomach acid: mineral preparations acting on the gastrointestinal tract, charcoal, or antacids (aluminum, calcium, and magnesium salts);
- a drug used to treat thyroid disease (thyroxine);
- a drug used to treat Parkinson's disease (methyldopa, levodopa, carbidopa);
- supplements and (or) drugs 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 drug 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 drug at the same time as whole grain products (bran, legumes, oilseeds), certain proteins (eggs), or foods and drinks containing calcium (cheese, milk, etc.). An interval should be maintained between taking iron salts and these foods (at least 2 hours).
Pregnancy, breastfeeding, and fertility
If the patient is pregnant or breastfeeding, suspects that they may be pregnant, or plans to have a child, they should consult their doctor or pharmacist before taking this drug.
Tardyferon can be used during pregnancy and breastfeeding.
Driving and using machines
It is unlikely that Tardyferon will affect the ability to drive and use machines.

Overdose symptoms 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), as well as liver and kidney failure.
In case of taking too much of the drug, you should immediately contact the emergency department for proper treatment.
