Tapering off long-term benzodiazepine use with or without group cognitive-behavioural therapy: three-condition, randomised controlled trial.
BACKGROUND
Benzodiazepine withdrawal programmes have never been experimentally compared with a nonintervention control condition.


AIMS
To evaluate the efficacy and feasibility of tapering off long-term benzodiazepine use in general practice, and to evaluate the value of additional group cognitive-behavioural therapy (CBT).


METHOD
A 3-month randomised, 3-month controlled trial was conducted in which 180 people attempting to discontinue long-term benzodiazepine use were assigned to tapering off plus group CBT, tapering off alone or usual care.


RESULTS
Tapering off led to a significantly higher proportion of successful discontinuations than usual care (62% nu. 21%). Adding group CBT did not increase the success rate (58% v. 62%). Neither successful discontinuation nor intervention type affected psychological functioning. Both tapering strategies showed good feasibilityin general practice.


CONCLUSIONS
Tapering off is a feasible and effective way of discontinuing long-term benzodiazepine use in general practice. The addition of group CBT is of limited value.
