Prescribing for children - mean weights

Prescribing for children - mean weights

The information in the table below has been extracted from the BNF. The table shows the mean values for weight by children's age. These values can be used to calculate doses in the absence of actual measurements. However, note that the child's actual weight might vary considerably from the values in the table and it is important to see the child to ensure that the value chosen is appropriate. In most cases, the child's actual weight should be obtained as soon as possible and the dose recalculated.
