Anaemia caused by a lack of iron is called iron-deficiency anaemia. Iron is needed to make haemoglobin which carries oxygen around in the bloodstream and is what makes red blood cells red.
If someone has iron-deficiency anaemia, it means that there is not enough oxygen being carried around the body. This can cause tiredness, breathlessness, palpitations, dizziness and headache.
Iron is found naturally in certain foods, but in some conditions where people do not get enough iron from their normal diet, an iron supplement may be useful.
Before taking iron supplements
Before taking iron supplements make sure your doctor or pharmacist knows:
- If you are pregnant, trying for a baby or breast-feeding.
- If you have bowel irritation or inflammation.
- If you are taking any other medicines, including those available to buy without a prescription, herbal and complementary medicines.
- If you have ever had an allergic reaction to this or to any other medicine.
How to take iron supplements
- Before starting this treatment, read the manufacturer's printed information leaflet from inside the pack.
- Iron supplements are absorbed better if they are taken an hour before meals. However, you may prefer to take your iron supplements with or just after your meals to reduce the risk of stomach irritation.
- Try to take your doses at the same times each day to avoid missing any.
- If you do forget to take a dose don't worry, just leave out the missed dose and take the next when it is due. Do not take two doses together to make up for a forgotten dose.
- If you suspect that you have taken, or someone else (and especially if it is a child) has taken, an overdose of iron, go to the accident and emergency department of your local hospital at once. Take the container with you, even if it is empty.
Getting the most from your treatment
- Do not take iron supplements for longer than a few months without medical advice from your doctor, nurse or pharmacist.
- If you buy any medicines, check with your pharmacist that they are safe to take with iron supplements. Some antacids may interfere with the way iron is absorbed.
- Iron supplements may darken your stools. This is completely harmless and is no cause for concern.
