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.

☞ Avoid sudden drug withdrawal. Taper dosage gradually to termination of therapy.
• Inform patient he may take drug with or without food; recommend taking it with food if it causes stomach upset.
• Caution patient to avoid driving and other hazardous activities until he knows how drug affects concentration and alertness.
