  • Acute severe anxiety, muscle spasm: 5-10mg IV repeated in 3-4 hours if necessary
  • Acute benzodiazepine withdrawal: give divided doses of diazepam equivalent to the patientÂ?s daily benzodiazepine consumption; if this is not known, give oral diazepam 20mg every 2 hours until withdrawal symptoms are controlled; gradually taper dosage over subsequent days
  • Elderly and/or debilitated patient: 2mg orally twice daily


  • Premedication: rectal/oral 0.2-0.4mg/kg
