    25 mg. of iron is required to produce a 1% rise in haemoglobin, the contents of each ampoule administered will raise the haemoglobin by 4%. It is therefore a simple matter to calculate how many ampoules of ‘ Ferrivenin’ will be required to correct the haemoglobin deficiency of the individual patient once the haemoglobin percentage has been determined. A more accurate method of calculation involves estimating the blood volume of the patient, but this is unnecessary for ordinary therapeutic purposes. — NOTE :—In chronic anaemia the iron storage organs may be severely depleted and it will then be necessary to administer a dose of ‘Ferrivenin’ about 50 per cent. above that calculated on the haemoglobin level alone. However, the criterion for adequate dosage will always be final correction of the haemoglobin deficit.
