Dosage & Administration

Adult: One Capsule daily before food or as directed by the physician.


Carbonyl Iron decreases the absorption of tetracycline antibiotics, quinolone antibiotics, levodopa, levothyroxine, methyldopa and penecillamine. Folic Acid interacts with antiepileptics, so plasma concentrations of phenobarbital, phenytoin and primidone are possibly reduced.


It is contraindicated in patients with known hypersensitivity to any of its component or those with Iron overload.

Side Effects

Gastrointestinal irritations such as nausea, anorexia, vomiting, discomfort, constipation and diarrhoea may occur. Patients may complain of dark stool. Carbonyl Iron pellets incorporated into the capsules to reduce the possibility of gastrointestinal irritations. Rarely there may be allergic reactions.

Pregnancy & Lactation

Use of any drug during first trimester of pregnancy should be avoided if possible. Thus administration of Iron during the first trimester requires definite evidence of Iron deficiency. Prophylaxis of Iron deficiency where inadequate diet calls for supplementary Zinc and Folic acid is justified during the remainder of pregnancy.

Precautions & Warnings

Special care should be taken in patients with Iron overload states, such as haemochromatosis, haemolytic anaemia or red blood cell aplasia. Failure to response to the treatment requires further investigations to exclude other causes of anaemia. In patients with renal failure there may be the risk of Zinc accumulation.
