What is it used for?
- Preventing and treating iron deficiency anaemia.
How does it work?
- Ferrograd tablets contain the active ingredient ferrous sulphate, which is a form of iron. Ferrous sulphate is also available without a brand name, ie as the generic medicine.
- Iron plays a vital role in production of haemoglobin, which is the oxygen-transporting substance found in red blood cells. If the diet does not contain enough iron, the body cannot make enough new red blood cells. This results in iron deficiency anaemia, with symptoms such as tiredness, palpitations, shortness of breath, dizziness and fainting.
- To treat iron deficiency anaemia, iron supplements such as this one are needed. The increased iron intake allows the body to increase its production of red blood cells.
- Ferrograd tablets are a 'modified-release' form of ferrous sulphate. They are designed to release the iron slowly over the day as the tablet passes through the gut. This may help to reduce the digestive side effects that can sometimes be a problem with iron supplements. However, if side effects are reduced compared to other iron tablets this may be because less iron is being absorbed, because Ferrograd tablets carry the iron into an area of the gut where absorption may be poor.
- The absorption of iron from the gut is decreased if it is taken at the same time as coffee, tea, eggs or milk. Its absorption is enhanced if it is taken at the same time as foods or supplements containing vitamin C (ascorbic acid).
How do I take it?
- One Ferrograd tablet should be taken once a day, or as directed by your doctor.
- The medicine should be taken before food on an empty stomach. However, if the tablets upset your stomach, then you may take them with or after food.
- The tablets should be swallowed whole and not chewed, crushed or broken.
- The absorption of iron may be reduced by tea, coffee, eggs and milk. You should avoid consuming these at the same time as taking Ferrograd tablets.
Not to be used in
- People with anaemia due to vitamin B12 deficiency (pernicious anaemia).
- People with anaemia due to folic acid deficiency.
- Genetic disease resulting in too much iron storage in the tissues (haemochromatosis).
- People with a disorder that affects storage of iron in the body (haemosiderosis).
- People with a condition where there is sudden loss of haemoglobin (oxygen carrying protein in the blood) in the urine at night (paroxysmal nocturnal haemoglobinuria).
- People with other disorders involving haemoglobin, such as sickle cell anaemia or thalassaemia.
- People receiving repeated blood transfusions.
- People with an active peptic ulcer.
- Inflammatory bowel disease such as ulcerative colitis or Crohn's disease.
- Children under 12 years of age. Other brands of iron are available for treating iron deficiency in children.

How can this medicine affect other medicines?
It is important to tell your doctor what medicines you are taking, including those bought without a prescription and herbal medicines, before you start treatment with this medicine. Similarly, check with your doctor or pharmacist before taking any new medicines while taking this one, to make sure that the combination is safe.
Iron supplements can affect the absorption of a number of medicines from the gut, which can make these medicines less effective. For this reason, it is recommended that iron supplements are taken at least two hours before or two hours after other medicines, in order to minimise this effect. The medicines for which this is most important are listed below:
- bisphosphonates, eg alendronate
- methyldopa (iron tablets may also reduce the blood pressure lowering effect of methyldopa)
- quinolone-type antibiotics, eg ciprofloxacin, norfloxacin, ofloxacin, levofloxacin
- tetracycline-type antibiotics, eg oxytetracycline, doxycycline, minocycline, tetracycline (these antibiotics also reduce the absorption of the iron supplements from the gut).
Zinc and calcium supplements reduce the absorption of iron supplements. Separate the medicines by at least two hours.
Antacids for heartburn or indigestion, such as magnesium carbonate, magnesium hydroxide, aluminium hydroxide and calcium carbonate may decrease the absorption of iron from the gut and thereby make the supplements less effective. Separate the medicines by at least two hours.
Trientene, used to treat Wilson's disease, also reduces the absorption of iron supplements from the gut, making them less effective unless the doses are separated by at least two hours.
Milk, milk-containing products, tea, coffee and eggs, may decrease iron absorption from the gut, while vitamin C (ascorbic acid) increases it.
