Using dosing tables to calculate total Cosmofer® dose

Published
Topics: DosingIron dextran

Dosing tables enable you to determine a total Cosmofer® dose and decide whether or not you need to split the dose into two parts.

Use these tables as part of a process

The tables below are provided by the manufacturer and enable calculation of doses. The manufacturer’s tables present a dose rounded to the nearest ampoule volume to reduce Comosfer® wastage. They should be used as part of a fuller process for Cosmofer® dose calculation.

For target haemoglobin 11g/dL

The table enables estimation of the total iron requirements (mg) for target haemoglobin of 11g/dL. Shaded cells indicate where the dose exceeds 20mg/kg; these higher doses should be divided (as described in our article on the full Cosmofer® process).

The table enables estimation of the total iron requirements (mg) for target haemoglobin of 12g/dL. Shaded cells indicate where the dose exceeds 20mg/kg; these higher doses should be divided (as described in our article on the full Cosmofer® process).

Using the dosing tables forms part of the process of safely and effectively using Cosmofer. You should consult all the steps in our article on the topic.
