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 sudden absorption of the entire dose of iron 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 prevent iron deficiency in pregnant women with inadequate dietary intake.
Tardyferon is indicated for use in children over 10 years of age 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 medicine (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 of age.
Iron deficiency supplementation should be, if possible, combined with treatment of the cause of the deficiency.
If a tablet gets into the airways, patients, especially the elderly and those with swallowing difficulties, may also be at risk of throat, esophagus (connecting the mouth to the stomach), or bronchial ulcers (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.
Children and adolescents
Tardyferon can be used in children over 10 years of age.
Tardyferon and other medicines
You should not take Tardyferon unless your doctor decides to do so.
Some medicines cannot be taken at the same time, while others require special changes (e.g. time of administration).
You should avoid taking Tardyferon if you are taking iron-containing medicines for injection.
The following medicines may require a dose adjustment. You should 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 acid in the stomach: mineral preparations acting on the digestive system, 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 (non-steroidal 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 you are currently taking or have recently taken any other medicine, including those available without a prescription, you should tell your 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), certain proteins (eggs), or foods and drinks containing calcium (cheese, milk, etc.). You should keep a gap between taking iron salts and these foods (at least 2 hours).

The tablets should be taken with a large glass of water, preferably before or during a meal, depending on gastrointestinal tolerance (except for specific foods mentioned in the "Tardyferon with food, drink, and alcohol" section).
Taking a higher dose of Tardyferon than recommended
Cases of iron salt overdose have been reported, especially in children as a result of swallowing a large amount of the 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 of the medicine, you should immediately contact the emergency department for proper treatment.
