4. Clinical particulars
4.1 Therapeutic indications

Prophylaxis and treatment of iron deficiency states.

4.2 Posology and method of administration

Adults and the elderly: One tablet daily (the foil enclosing the tablet is printed with days of the week in sequence).

In severe or refractory iron deficiency, one tablet may be given twice a day.

Children: Ferrous Fumarate tablets are not intended for the treatment of children.

Method of administration: Oral

4.3 Contraindications

Known hypersensitivity to any of the ingredients of the product.

Paroxysmal nocturnal haemoglobinuria, haemosiderosis, haemochromatosis, active peptic ulcer, repeated blood transfusions, regional enteritis, and ulcerative colitis. Ferasday tablets must not be used in anaemias other than those due to iron deficiency.

4.4 Special warnings and precautions for use

Some post gastrectomy patients show poor absorption of iron. Care is needed when treating patients with iron deficiency anaemia in patients with treated or controlled peptic ulceration. Duration of treatment of uncomplicated iron deficiency anaemia should not usually exceed 6 months (or 3 months after reversal of the anaemia has been achieved).

Since anaemia due to combined iron and vitamin B12 or folate deficiencies may be microcytic in type, patients with microytic anaemia resistant to therapy with iron alone should be screened for vitamin B12 or folate deficiency. Ferrous Fumarate tablets should be kept out of the reach of children.

The label will state:

Important Warning: Contains Iron.

Keep out of the reach and sight of children, as overdose may be fatal.

This will appear on the front of the pack within a rectangle, in which there is no other information.

4.5 Interaction with other medicinal products and other forms of interaction

Iron reduces the absorption of penicillamine, bisphosphonates, ciprofloxacin, entacapone, levodopa, levofloxacin, levothyroxine (thyroxine) (give at least 2 hours apart), moxifloxacin, mycophenolate, norfloxacin, ofloxacin, zinc. Absorption of both iron and antibiotic may be reduced if Ferrous Fumarate tablet is given with tetracycline. Absorption of oral iron is reduced by calcium salts, Magnesium salts (as magnesium trisilicate), Trientine.

Chloramphenicol delays plasma iron clearance, incorporation of iron into red blood cells and interferes with erythropoiesis. Some inhibition of iron absorption may occur if it is taken with cholestyramine, tea, eggs or milk.

Avoid concomitant use of iron with dimercaprol.

Oral iron antagonises hypotensive effect of methyldopa.

4.6 Pregnancy and lactation

Pregnancy

Ferrous fumarate tablets can be used during pregnancy if clinically indicated.

Lactation

No adverse effects of ferrous fumarate have been shown in breastfed infants of treated mothers. Ferrous fumarate tablets can be used during breast-feeding if clinically indicated.

4.7 Effects on ability to drive and use machines

None known.

4.8 Undesirable effects

• Gastro-intestinal irritation and darkening of stools can occur with iron salts. Nausea and epigastric pain are dose-related but the relationship between dose and altered bowel habit (constipation or diarrhoea) is less clear. Oral iron, particularly modified-release preparations, can exacerbate diarrhoea in patients with inflammatory bowel disease; care is also needed in patients with intestinal strictures and diverticular disease.

• Iron preparations taken orally can be constipating, particularly in older patients and occasionally lead to faecal impaction.

• If side-effects occur, the dose may be reduced; alternatively, another iron salt may be used but an improvement in tolerance may simply be a result of a lower content of elemental iron.

• Iron preparations are a common cause of accidental overdose in children

Reporting of side effects

Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions via the Yellow Card Scheme at: www.mhra.gov.uk/yellowcard.

4.9 Overdose

Symptoms:

Ingestion of 20 mg/kg elemental iron is potentially toxic and 200-250 mg/kg is potentially fatal. No single method of assessment is entirely satisfactory - clinical features as well as laboratory analysis must be taken into account. The serum iron taken at about 4 hours after ingestion is the best laboratory measure of severity.

Serum Iron

Severity

< 3 mg/L (55 micromol/L)

Mild toxicity

3-5 mg/L (55-90 micromol/L)

Moderate toxicity

> 5 mg/L (90 micromol/L)

Severe toxicity

Early signs and symptoms include nausea, vomiting, abdominal pain and diarrhoea. The vomit and stools may be grey or black. In mild cases early features improve but in more serious cases there may be evidence of hypoperfusion (cool peripheries and hypotension), metabolic acidosis and systemic toxicity. In serious cases there can be recurrence of vomiting and gastrointestinal bleeding, 12 hours after ingestion. Shock can result from hypovolaemia or direct cardiotoxicity.

Evidence of hepatocellular necrosis appears at this stage with jaundice, bleeding, hypoglycaemia, encephalopathy and positive anion gap metabolic acidosis. Poor tissue perfusion may lead to renal failure. Rarely, gastric scarring causing stricture or pyloric stenosis (alone or in combination) may lead to partial or complete bowel obstruction 2-5 weeks after ingestion.

Management:

Supportive and symptomatic measures include ensuring a clear airway, monitoring of cardiac rhythm, BP and urine output, establishing IV access and administering sufficient fluids to ensure adequate hydration. Consider whole bowel irrigation. If metabolic acidosis persists despite correction of hypoxia and adequate fluid resuscitation, an initial dose of 50 mmol sodium bicarbonate may be given and repeated as necessary, for adults guided by arterial blood gas monitoring (aim for a pH of 7.4). Consider the use of desferrioxamine, if the patient is symptomatic (other than nausea), serum iron concentration is between 3-5 mg/L (55-90 micromol/L) and still rising. Haemodialysis does not remove iron effectively but should be considered on a supportive basis for acute renal failure as this will facilitate removal of the iron-desferrioxamine complex.

5. Pharmacological properties
5.1 Pharmacodynamic properties

Iron is an essential constituent of the body, and is necessary for haemoglobin formation and the oxidative processes of living tissues. Iron and iron salts should be given for the treatment or prophylaxis of iron deficiency anaemias. Preparations of iron are administered by mouth, by intramuscular or intravenous injection.

Soluble ferrous salts are most effective by mouth. Ferrous fumarate is an easily absorbed source of iron for replacement therapy. It is a salt of ferrous iron with an organic acid and is less irritant to the gastro-intestinal tract than salts with inorganic acids.

5.2 Pharmacokinetic properties

Once in the stomach, the acid conditions of the gastric contents cause the dissociation of ferrous fumerate and ferrous ions are liberated. These ions are absorbed through the proximal portion of the duodenum.

The ferrous iron absorbed by the mucosal cells of the duodenum is oxidised to the ferric form, and this is bound to protein to form Ferritin.

Ferritin in the mucosal cells releases iron into the blood, where it is bound to transferrin and is passed onto the iron stores in the liver, spleen, and bone marrow.

These stores constitute a reserve of iron for synthesis of haemoglobin, myoglobin, and iron containing enzymes.

Iron is lost from the body through loss of cells i.e, urine, faeces, hair, skin, sputum, nails, sloughing of mucosal cells, and through blood loss.

Ferrous fumarate has the same pattern of absorption and excretion as dietary iron.
