In 1981, a paper by Gosselin estimated that the lethal dose is between 50 and 500 mg/kg. Doses as high as 15–20 mg/kg are taken by some recreational users. A single case study suggests that the antidote to dextromethorphan overdose is naloxone, administered intravenously. [17]

The dose of bupropion in the study was lower than the target dose recommended for clinical practice.

The procedure is to take the child's weight in pounds, divide by 150 lb, and multiply the fractional result by the adult dose to find the equivalent child dosage.For example, if an adult dose of medication calls for 30 mg and the child weighs 30 lb, divide the weight by 150 (30/150) to obtain 1/5 and multiply 1/5 times 30 mg to get 6 mg.
