➣ Status epilepticus and severe recurrent convulsive seizures
Adults: 5 to 10 mg I.V. slowly, repeated as needed q 10 to 15 minutes, to a maximum of 30 mg; may repeat regimen if needed in 2 to 4 hours. May give I.M. if I.V. delivery is impossible.
Children ages 5 and older: 1 mg I.V. slowly q 2 to 5 minutes, to a maximum of 10 mg; repeat in 2 to 4 hours if needed. May give I.M. if I.V. delivery is impossible.
Children over 1 month to 5 years: 0.2 to 0.5 mg I.V. slowly q 2 to 5 minutes, to a maximum of 5 mg I.V. May give I.M. if I.V. delivery is impossible.
➣ Muscle spasm associated with local pathology, cerebral palsy, athetosis, "stiff-man" syndrome, or tetanus
Adults: 2 to 10 mg P.O. three to four times daily. Or initially, 5 to 10 mg I.V. or I.M., repeated in 3 to 4 hours if needed. Tetanus may necessitate higher dosages.
Elderly or debilitated patients: Initially, 2 to 2.5 mg P.O. once or twice daily, increased gradually as needed and tolerated
Children ages 5 and older: 5 to 10 mg I.M. or I.V., repeated q 3 to 4 hours as needed to control tetanus spasm
Children over 1 month to 5 years: 1 to 2 mg I.M. or I.V. slowly, repeated q 3 to 4 hours as needed to control tetanus spasm
➣ Acute alcohol withdrawal
Adults: Initially, 10 mg P.O. three to four times during first 24 hours, decreased to 5 mg P.O. three to four times daily p.r.n. Or initially, 10 mg I.M. or I.V.; then 5 to 10 mg I.M. or I.V. in 3 to 4 hours p.r.n.
