related to height
and age (see inside
back cover).
Body surface area (BSA)
estimates are sometimes
preferable to body-weight for calculation of
paediatric
doses since many physiological
phenomena correlate
better with body surface area. Body surface area can be
estimated from weight.

Where the dose for children is not
stated,
prescribers
should consult
BNF for Children
or seek advice from a
medicines information centre.
Dose frequency
Antibacterials are generally given at
regular
intervals throughout
the day.
Some flexibility
should be allowed in children to avoid waking them
during the night. For example, the night-time dose may
be given at the child’s bedtime.
Where new or
potentially toxic drugs are used,
the
manufacturers’ recommended doses should be carefully
followed.
