Legend:
- * Benzodiazepine doses should be reduced to lowest effective dose, if possible, in the elderly (patients greater than 65 years of age), to minimize oversedation; these patients are more sensitive to pharmacologic effects of these agents
- ^May give second diazepam nasal dose at least 4 hours after first dose, if necessary; may not use more than 2 doses to treat single episode; may not treat more than 1 episode/5 days or more than 5 episodes/month
- + Dose rounded up to nearest commercially available unit dose (in multiples of 2.5 mg); should not be administered by caregivers outside the hospital more frequently than one course every 5 days with a maximum of 5 courses per month; not for chronic administration to minimize potential for development of tolerance
- ! May give second midazolam nasal dose 10 minutes after first dose, if necessary; may not use more than 2 doses to treat a single episode. Nasal midazolam should be used to treat no more than one episode every three days and no more than 5 episodes per month
- # In elderly patients, doses up to 120 mg/day may be needed to treat AW
