⚠ Medical warning

Stopping this medicine suddenly after regular use can cause dangerous withdrawal, including seizures (convulsions) and delirium, the label says. Don’t stop or cut down on your own; talk to your prescriber first. If someone has a seizure, hallucinations or severe confusion, call 911.

Quick answer

The NHS advises against stopping zolpidem suddenly, because it can cause withdrawal symptoms such as agitation or anxiety, and says your doctor will reduce the dose gradually. It also says zolpidem isn’t usually prescribed for longer than 4 weeks because of tolerance. In Ambien trials, withdrawal-type symptoms such as fatigue, nausea, flushing, lightheadedness, crying, vomiting, stomach cramps, panic and nervousness were reported within 48 hours of the last dose. The label says sedative-hypnotic withdrawal ranges from mild insomnia to convulsions and delirium.

Symptoms, phase by phase

The Ambien label says withdrawal signs and symptoms have been reported after a rapid dose decrease or abrupt stop. In clinical trials, events meeting criteria for uncomplicated sedative withdrawal within 48 hours of the last dose included fatigue, nausea, flushing, lightheadedness, uncontrolled crying, vomiting, stomach cramps, panic attack, nervousness and abdominal discomfort. More generally, it says sedative-hypnotic withdrawal ranges from mild dysphoria and insomnia to a syndrome that can include cramps, vomiting, sweating, tremors, convulsions and delirium. Interestingly, the label found no objective (sleep-lab) evidence of rebound insomnia at recommended doses, though many people feel their sleep is worse for a night or two.

Dose. The label says the risk of dependence increases with dose and duration of treatment.
Alcohol and other sedatives. The label says combining zolpidem with other CNS depressants increases the risk of CNS depression.

Tapering

The NHS says a doctor can help you come off gradually if you’ve taken it for a long time. We don’t publish dose-by-dose schedules. Your prescriber should set your plan, and adjust it if symptoms appear.

Tips for getting through it

Wake up and get out of bed at the same time every day (NHS)
Avoid tea or coffee for at least 6 hours before bed (NHS); avoid devices right before bed
Ask a GP about cognitive behavioural therapy (CBT) for insomnia, which the NHS says may be offered

How long does Ambien withdrawal last?

Trial reports show symptoms within 48 hours of the last dose. The label doesn’t give a total duration, so tell your prescriber if symptoms don’t settle.

Will I ever sleep without Ambien?

The NHS says insomnia usually gets better by changing your sleeping habits, and a GP may offer cognitive behavioural therapy (CBT).
