Treating chronic insomnia: An alternating medication strategy

Abstract

Vol. 22, No. 10 25 Patients with chronic insomnia that does not improve with nonpharmacologic techniques often develop tolerance to sedative medications (benzodiazepines) prescribed for nightly use. When nonbenzodiazepine medications are used, tachyphylaxis can develop and these medications no longer initiate or maintain sleep. Strategies that alternate between these 2 types of agents are simple to follow and may allow patients to maintain sensitivity to both types of medications. In this article, I review the types, causes, evaluation, and treatment of insomnia; describe an alternating medication strategy to help patients avoid developing tolerance/tachyphylaxis; and present 3 fictional case vignettes to illustrate this approach.
