1. What Tardyferon is and what it is used for
Tardyferon contains iron.
The need for iron is increased in women during pregnancy, after childbirth, in breastfeeding mothers, and in adolescents during growth periods. Iron deficiency or iron-deficiency anaemia can be prevented or treated using a medicine called Tardyferon.
In this combination of iron and excipients, Fe ions are released slowly, which prevents the sudden absorption of the entire iron dose into the blood serum.
This reduces the number of observed adverse effects and makes it easier for the patient to adhere to the treatment. The slow release allows iron ions to reach the distal segments of the intestine, which—apart from the duodenum—have the capacity to absorb iron. Limiting iron absorption to the upper intestinal segments is caused by iron saturation processes.
Like all iron-containing medicines, Tardyferon has no effect on erythropoiesis (red blood cell production) or on anaemia caused by factors other than iron deficiency.
Tardyferon is used in the treatment of iron-deficiency anaemia and in the prevention of iron deficiency in pregnant women with inadequate dietary intake.
Tardyferon is indicated for use in children over 10 years of age and in adults.
2. Important information before using Tardyferon
When not to use Tardyferon
- if the patient is allergic to iron(II) sulphate or any of the other ingredients of this medicine (listed in section 6);
- if the patient has been diagnosed with iron overload;
- if the patient has a type of anaemia (reduced haemoglobin concentration or insufficient number of red blood cells) not caused by iron deficiency, or one associated with excess iron in the body (e.g. thalassaemia, refractory anaemia, or anaemia due to bone marrow failure).
Warnings and precautions
Before starting treatment with Tardyferon, discuss this with your doctor or pharmacist.
The toxic dose of iron is lower in children than in adults. Administration of Tardyferon is not recommended in children under 10 years of age.
If the patient is receiving Tardyferon due to iron-deficiency anaemia, the doctor will combine the treatment with diagnosis and management of the underlying cause of the disease.
If iron-deficiency anaemia occurs in the course of inflammatory diseases, treatment with Tardyferon will not be effective.
If the patient has difficulty swallowing, they should inform their doctor.
If a tablet accidentally enters the patient's airways (tablet aspiration), it may cause injuries such as necrosis (tissue death) or bronchitis (inflammation of the main airways in the lungs) or oesophagitis (inflammation of the oesophagus – the passage connecting the mouth to the stomach). These may subsequently lead to bronchial stenosis. Symptoms such as persistent cough, coughing up blood, and/or shortness of breath may occur, even if aspiration occurred several days to several months earlier.
In case of improper swallowing of the medicine and occurrence of one or more of the above symptoms, contact a doctor or the nearest emergency department immediately to determine whether airway damage has occurred and to receive appropriate treatment.
Melanosis of the gastrointestinal tract (pigmentation in the gastrointestinal system) has been reported in medical literature in elderly patients with renal failure, diabetes (abnormally high blood sugar levels) and/or arterial hypertension (high blood pressure), who were treated with multiple drugs for these conditions and received iron supplementation due to concomitant anaemia. If the patient is scheduled for gastrointestinal surgery, the surgeon should be informed about iron intake, as melanosis may complicate the surgical procedure.
Cases of gastric ulceration and gastrointestinal bleeding have been reported in patients taking iron tablets. If such symptoms occur, the doctor may recommend switching from tablets to a liquid formulation (see section 4).
Due to the risk of oral mucosal ulceration and tooth discoloration, tablets should not be sucked, chewed, or held in the mouth, but swallowed whole with water. If following this instruction is not possible or if swallowing difficulties occur, the patient should contact their doctor.
Children and adolescents
Tardyferon may be used in children over 10 years of age.
Tardyferon with other medicines
Do not take Tardyferon unless advised by a doctor.
Inform your doctor about all medicines currently or recently taken, as well as any medicines the patient plans to take.
Some medicines should not be used together, while others require special adjustments (e.g. timing of administration).
Avoid using Tardyferon if the patient is receiving injectable iron-containing medicines.
Do not take Tardyferon within 2 hours after taking any of the following medicines:
- certain antibiotics (tetracyclines, fluoroquinolones, cefdinir);
- a medicine used in the treatment of chronic urinary tract infection (acetylhydroxamic acid);
- medicines used in the treatment of HIV infection (integrase inhibitors, bictegravir [bictegravir should be administered at least 2 hours before iron or taken with food]);
- medicines used in the treatment of weakened bones (bisphosphonates);
- medicines used in the treatment of joint diseases, Wilson's disease (penicillamine, trientine);
- antacids (containing aluminium, calcium, and/or magnesium salts);
- a medicine used in the treatment of thyroid disease (thyroxine);
- medicines used in the treatment of Parkinson's disease (methyldopa, levodopa, carbidopa, entacapone);
- supplements and/or medicines containing zinc or calcium;
- cholestyramine (a medicine used to reduce elevated blood cholesterol levels): Tardyferon should be administered 1–2 hours before or 4 to 6 hours after cholestyramine;
- NSAIDs (non-steroidal anti-inflammatory drugs) – these should be taken with food to reduce gastric and intestinal mucosal irritation and lower the risk of bleeding associated with their use.
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 simultaneously with whole-grain products (bran, legumes, oilseeds), certain proteins (e.g. from eggs), or foods or drinks containing calcium (cheese, milk, etc.). A minimum interval of 2 hours should be maintained between administration of iron salts and these foods.
Pregnancy, breastfeeding and fertility
If the patient is pregnant, breastfeeding, suspects she may be pregnant, or is planning to have a baby, she should consult her doctor or pharmacist before using this medicine.
There are no studies in women during the first trimester of pregnancy that would allow assessment of the risk of developmental abnormalities. However, neither in professional literature nor during post-marketing surveillance have any cases of congenital malformations been reported. Numerous published data on women during the second and third trimesters of pregnancy do not indicate an increased risk of malformations or fetal or neonatal toxicity. Therefore, Tardyferon may be used during pregnancy if clinically indicated.
Iron passes into breast milk in small amounts. The mother's diet does not affect its concentration. No adverse effects on newborns/infants are expected.
Tardyferon may be used during breastfeeding.
Driving and using machines
It is unlikely that Tardyferon will affect the ability to drive or operate machinery.
Tardyferon contains less than 1 mmol (23 mg) of sodium per tablet, meaning the medicine is considered "sodium-free".
3. How to use Tardyferon
This medicine should always be taken exactly as directed by your doctor or pharmacist. If in doubt,
consult your doctor or pharmacist.
Tardyferon is indicated for children over 10 years of age and adults.
Tardyferon is administered orally.
Treatment of iron deficiency anemia
Children over 10 years of age and adults: 1 to 2 tablets per day.
The duration of treatment should be sufficiently long to correct anemia and replenish iron stores.
Treatment may last at least 3 to 6 months and may be extended if necessary, in agreement with your doctor.
Prophylactic treatment
- Latent iron deficiency: 1 tablet (corresponding to 80 mg Fe) once daily or every other day.
- Pregnant women: 1 tablet every other day during the last two trimesters of pregnancy (or from the 4th month of pregnancy).
Tardyferon tablets are taken orally.
The tablet should be swallowed whole with water. Do not suck, chew, or hold the tablet in the mouth.
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 section “Tardyferon with food, drink and alcohol”).
Taking more Tardyferon than recommended
If an excessive amount of medicine is taken, contact your doctor or the nearest emergency department immediately to initiate appropriate treatment, especially if overdose occurs in a child.
Symptoms of iron overdose include:
- severe gastrointestinal irritation, which may lead to tissue necrosis (necrosis of gastrointestinal mucosa). Main symptoms are: abdominal pain, nausea, vomiting (sometimes containing blood), and diarrhea (sometimes with black stools). This may be accompanied by metabolic acidosis and shock with the following main symptoms: rapid or shallow breathing, increased heart rate, headache, confusion, drowsiness, fatigue, loss of appetite, stomach pain, vomiting, and sudden drop in blood pressure, which may lead to loss of consciousness with seizures (coma).
- signs of impaired kidney function (marked reduction in urine output) and liver function (pain in the upper right abdomen, yellowing of the skin and eyes, dark urine).
Long-term consequences of overdose may also include gastrointestinal strictures (stenosis), characterized by nausea, bloating, constipation, and abdominal distension.
If you forget to take Tardyferon
If you miss a dose at the usual time, take it as soon as possible. However, if it is almost time for the next dose, do not take the missed dose. Take the next tablet at the usual time.
Do not take a double dose to make up for a missed dose.
If you have any further questions about the use of this medicine, consult your doctor or pharmacist.
Stopping Tardyferon treatment
Tardyferon should be taken for as long as your doctor recommends. Stopping treatment too early may result in recurrence of the condition.
If you have any further questions about the use of this medicine, consult your doctor or pharmacist.
