⚠ Medical warning

Stopping benzodiazepines suddenly can be life-threatening. Never stop or cut your dose quickly on your own. Talk to your prescriber about a slow, personal taper plan. Call 911 for a seizure, confusion or hallucinations.

Quick answer

NHS Scotland’s prescribing guidance says benzodiazepine withdrawal symptoms may start within a day of stopping a short-acting benzo such as lorazepam (Ativan), but at any time up to 3 weeks after stopping a long-acting one such as diazepam (Valium). The FDA warns that stopping suddenly or reducing too fast can cause seizures, which can be life-threatening. Some people have protracted withdrawal lasting beyond 4 to 6 weeks and, in some cases, up to 12 months.

What makes withdrawal longer or shorter

Short- vs long-acting. Short-acting benzos tend to cause withdrawal sooner.
Dose and how long you’ve taken them.
How fast you reduce. Stopping suddenly or tapering too fast raises the risk of severe withdrawal.
Other substances, especially alcohol or opioids.

When to see a doctor or get help now

Before you change your dose at all.
