WHAT IS FERINJECT
FERINJECT is an intravenous iron preparation, a medicine that is given in the treatment of iron deficiency conditions. It contains iron in the form of ferric carboxymaltose, an iron carbohydrate compound. Iron is an essential element required for the oxygen-carrying capacity of haemoglobin in red blood cells and of myoglobin in muscle tissue. Moreover, iron plays an important role in many other vital processes in the human body.
WHAT FERINJECT IS GIVEN FOR
FERINJECT is given for the treatment of patients with iron deficiency, when oral iron preparations are ineffective or cannot be used. The aim of the therapy is to replenish body iron stores and to remedy anaemia, a reduced level of haemoglobin due to iron deficiency. It is also used when there is a clinical need to deliver iron rapidly.
Before administration, your doctor will perform a blood test to calculate the dose of FERINJECT you require.
BEFORE YOU ARE GIVEN FERINJECT
When you must not be given FERINJECT
- if you are hypersensitive (allergic) to ferric carboxymaltose or any of the other ingredients of FERINJECT,
- if you have anaemia not caused by iron deficiency,
- if you have iron overload (too much iron in your body) or disturbances in utilisation of iron.
You must tell your doctor if
- if you are under the age of 14 years.
- you have an infection, asthma, eczemas, allergies or liver disorders.
- you are pregnant or breastfeeding.
- if you have or have had low levels of phosphate in the blood.
You should be aware that:
Intravenous iron preparations can cause severe allergic reactions. These allergic reactions may include chest pain. Tell your doctor immediately if you experience it.
Taking other medicines
If FERINJECT is given together with oral iron preparations, then these oral preparations will be less effective.
Please tell your doctor if you are taking or have recently taken any other medicines, including medicines obtained without prescription.
Important information about some of the ingredients of FERINJECT
This medicinal product contains 5.5 mg (or 0.24 mmol) sodium per millilitre of undiluted solution and is to be taken into consideration by patients on a controlled sodium diet.
HOW FERINJECT IS GIVEN
Your doctor can administer FERINJECT by three possible routes: undiluted by injection, during haemodialysis, or diluted by infusion.
- by injection, you may receive up to 20 mL of FERINJECT, corresponding to 1000 mg of iron, once a week directly into the vein.
- if you are on dialysis, you may receive FERINJECT during a haemodialysis session via the dialyser. The maximum dose of FERINJECT during haemodialysis is 200 mg (4 mL).
- by infusion, you may receive up to 20 mL of FERINJECT, corresponding to 1000 mg of iron, once a week directly into the vein. Because FERINJECT is diluted with sodium chloride solution for the infusion, it may have a volume of up to 250 mL and appear as a brown solution.
Your doctor will take responsibility for determining the appropriate dose and choosing the method, frequency and duration of your treatment. You may be re-assessed after 4 weeks to determine whether you need more Ferinject injections. Ferinject will be administered in a setting where possible allergic reactions can receive appropriate and prompt treatment.
You will be observed for about 30 minutes by your doctor or nurse after each administration.
In patients with liver disorders, iron status will be carefully monitored by the doctor to avoid iron overload.
Overdose can cause accumulation of iron in storage sites. Your doctor will monitor iron parameters such as serum ferritin and transferrin saturation to avoid iron accumulation.
The risk of accidental overdosing is minimal.
POSSIBLE UNWANTED EFFECTS
Like all medicines, FERINJECT can cause unwanted effects, although not everybody gets them.
Clinical studies experience
Reported side effects are either common (occurring in less than 1 in 10 and more than 1 in 100 patients) or uncommon (occurring in less than 1 in 100 and more than 1 in 1000 patients).
The following symptoms were common: headache, dizziness, high blood pressure, flushing, nausea, injection/infusion site reactions, low blood phosphate levels.
The following symptoms were uncommon: allergic reaction, tingling or numbness of the hands or feet, fast heart rate (tachycardia), low blood pressure, difficulty breathing, taste disturbance, vomiting, indigestion, wind, stomach pain, constipation, diarrhoea, itchiness, hives (urticaria), redness of skin (erythema), rash, muscle pain, muscle spasm, back pain, joint pain, pain in extremity, fever, fatigue, chest pain, swelling of hands, ankles or feet, pain and chills. Long-lasting brown discoloration of the skin may occur due to leakage of the drug at the injection site.
The following symptoms were rare: anaphylactoid reactions, generally feeling unwell.
Some blood parameters may change temporarily, which could be detected in laboratory tests.
The following changes in blood parameters are uncommon: increase of the liver enzyme alanine aminotransferase, increase of the liver enzymes aspartate aminotransferase, gamma-glutamyltransferase, blood lactate dehydrogenase and blood alkaline phosphatase.
Post marketing experience
As part of the continuing post-marketing surveillance of FERINJECT, the following side effects have been reported:
Anxiety, loss of consciousness, dizziness (vertigo), feeling faint (pre-syncope), fainting (syncope), wheeze (bronchospasm), swelling (angioedema), dermatitis, pallor, face swelling, influenza like illness, low blood phosphate levels which might cause your bones to become soft (hypophosphateamic osteomalacia), skin discolouration distant to the injection site and chest pain which can be a sign of a potentially serious allergic reaction called Kounis syndrome.
There is no efficacy or safety data on the use of FERINJECT in pregnancy before 16 weeks’ gestation. Iron deficiency occurring in the first trimester of pregnancy can in many cases be treated with oral iron.
There is limited experience with the use of FERINJECT in women in pregnancy from 16 weeks’ gestation). If iron treatment is needed in pregnancy, oral iron should be used where possible and FERINJECT only used where the benefit outweighs the risk.
Slow heartbeat may occur in unborn babies whose mothers have been administered intravenous iron due to allergic reactions in the mother.
Iron treatment including FERINJECT may worsen infection.
Ask your doctor for more information.
If any of the side effects becomes serious, or if you notice any side effects not listed in this leaflet, please tell your doctor.
