Six children with tuberculous infection were given their daily prescribed doses of isoniazid by the oral and the intramuscular route on different days. The plasma concentrations reached after both routes of administration were nearly equivalent. The plasma half-life of isoniazid ranged from 1.6 to 4.8 hours. The observed plasma concentrations in these children were higher than those reported in many adults. This difference is due to the larger doses of isoniazid prescribed for children.
