Pharmacists and carers often struggle to provide the correct therapeutic dose of paracetamol for overweight kids which could lead to complications as high doses are often fatal while lower doses could lead to more serious illnesses. The authors surveyed 45 carers and 28 community pharmacists to find out what dose of paracetamol they thought would be appropriate for an eight year old child, weighing 25, 32, or 50 kg.
They also observed the doses given to 86 children, one in three of whom was overweight/obese, in the emergency care department of a specialist children's hospital.
The recommended paracetamol dose for children ranges between 15 and 20 mg/kg every 4 to 6 hours, up to a maximum of 60 mg/kg per day - extended to 90 mg/kg per day if under medical supervision.
But these doses are for children who are average/normal weight for their age. Current expert opinion suggests that doses should be reduced in children who are more than 120% above their ideal body weight, but it is unclear whether children should be dosed according to their actual, rather than their ideal, body weight, say the authors.
The survey results showed that while most carers and pharmacists knew the correct dose for a normal weight child, their responses varied widely as the hypothetical child's weight increased.
By the time they were faced with the third scenario of the 50 kg child, the pharmacists recommended a twofold variation in dose; and one in four carers did not even answer the question.

And when corrected for ideal body weight, almost two out of three carers and three out of four pharmacists would have given the child a dose above 20 mg/kg.

"Simple evidence based dosing guidelines must be developed and communicated to practitioners to reduce the potential for confusion, which may lead to adverse consequences for these children," conclude the authors. This is extremely important they add, as "childhood obesity will almost certainly continue to be an issue for many years to come."
