Sleep-related eating disorder (SRED) is treatable and a reversible cause of obesity. The choice of medication depends on:
- which form of Sleep-related eating disorder (SRED) the patient exhibits (drug-induced or idiopathic)
- whether the patient has treatable comorbid conditions.
Temazepam. Switch patients whose Sleep-related eating disorder (SRED) is triggered by zolpidem or another hypnotic to a different agent. We have had excellent success with temazepam, 15 to 30 mg at bedtime.
Self-induced emesis or other purging behavior usually is not seen in Sleep-related eating disorder (SRED)
Topiramate. For idiopathic Sleep-related eating disorder (SRED) or the sleepwalking variant of Sleep-related eating disorder (SRED), trials from 2 academic institutions suggest that off-label use of topiramate, 25 to 150 mg at bedtime, may be the treatment of choice.
Start topiramate at 25 mg, and increase in 25-mg increments every 5 to 7 days until the night eating episodes are eliminated. Paresthesias, visual symptoms, and (rarely) renal calculus are reported side effects.
Other medications. Other agents that have shown at least some benefit in patients with Sleep-related eating disorder (SRED) include dopaminergic agonists, opiates, and clonazepam. Patients with Sleep-related eating disorder (SRED) and a history of chemical dependency may respond to combined levodopa, trazodone, and bupropion (dopaminergic/noradrenergic antidepressant) therapy at bedtime. Also focus treatment on any coexisting sleep disorder, such as RLS or OSA.
