Benzodiazepine dependence and withdrawal in elderly patients
E Schweizer, WG Case and K Rickels
Department of Psychiatry, University of Pennsylvania, Philadelphia.
Severity of withdrawal symptoms and clinical outcome were compared in 19
elderly and 22 younger benzodiazepine-dependent patients matched for
benzodiazepine half-life, dosage, and duration of treatment. During gradual
taper of benzodiazepine doses, the elderly patients showed significantly
less severe withdrawal symptoms on several clinical measures and a
comparably favorable outcome. Approximately half of each group remained
benzodiazepine free for at least 4 weeks. Both groups of patients tolerated
drug discontinuation without serious consequences such as seizures or
psychosis. Tapered benzodiazepine withdrawal did not appear to be more
risky for the elderly group than for the younger patients.
