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.

In rats, this dose was 1000 mg/kg/day, which is approximately 24 times a human dose of 200 mg twice daily based on mg/m 2 /day. In rabbits, the highest dose tested was 90 mg/kg/day, which is approximately four times a human dose of 200 mg twice daily based on mg/m 2 /day. This dose produced severe maternal toxicity and resulted in fetal ...
[6] [9] In a sample of 16 healthy subjects, a single mid-range 200 μg oral dose of LSD was found to produce mean maximal concentrations of 4.5 ng/mL at a median of 1.5 hours (range 0.5–4 hours) post-administration.
