Quetiapine (Seroquel) withdrawal
Here is what the FDA-approved label for Quetiapine (Seroquel) actually says about stopping it — not a secondhand summary. The single most important point applies to every drug on this list: don’t stop abruptly on your own.
What the label says about stopping Quetiapine
The label has a Discontinuation Syndrome section (5.19). It states that acute withdrawal symptoms - insomnia, nausea, and vomiting - have been described after abrupt cessation of atypical antipsychotics including quetiapine. In short-term trials with the XR formulation, an aggregate 12.1% of patients experienced one or more discontinuation symptoms after abrupt cessation (vs 6.7% on placebo), the named symptoms being insomnia, nausea, headache, diarrhea, vomiting, dizziness, and irritability, which usually resolved within about a week. The label states that gradual withdrawal is advised, meaning a prescriber-managed taper rather than abrupt stopping. This is not in the boxed warning (the boxed warning concerns increased mortality in elderly dementia patients and suicidality, not withdrawal).
Why the taper matters
After your body adapts to a drug taken regularly, removing it too fast forces an abrupt readjustment — that is what withdrawal (also called discontinuation) is. A prescriber-managed taper steps the dose down gradually so the adjustment is gentle, and it can be slowed if a step is hard. This is why the fix is never to “push through” a cold-turkey stop, and never to piece a schedule together from a forum. Talk to the prescriber who manages your dose before you change anything.
And alcohol with Quetiapine?
The label addresses alcohol. In Drug Interactions it states that quetiapine potentiated the cognitive and motor effects of alcohol in a clinical trial in subjects with psychotic disorders, and that alcoholic beverages should be limited while taking quetiapine. The Medication Guide is more direct, telling patients not to drink alcohol while taking quetiapine because it may make some side effects worse. This is an additive CNS effect (impaired cognition and motor function), not a disulfiram-like reaction.
Frequently asked questions
Can I stop Quetiapine suddenly?
Not on your own. Quetiapine's FDA label describes a discontinuation or withdrawal issue (summarized above), and stopping abruptly after regular use can bring it on. The safe route is a gradual, prescriber-managed taper — a cold-turkey stop decided alone is exactly what the label warns against.
How long does Quetiapine withdrawal last?
There is no single answer and the FDA label does not set a fixed timeline. In general it depends on the drug's half-life, your dose, and how long you took it — and a slow, prescriber-guided taper is what shortens and softens it. Ask the prescriber who manages your dose to map a schedule to your situation.
How do you safely taper off Quetiapine?
Tapering means lowering the dose in steps over weeks so your body adjusts, under the prescriber who knows your history. If a step is too hard, the schedule can be slowed — that flexibility is the point. Do not design a taper yourself from an internet schedule, and do not use alcohol or other sedatives to cope with symptoms.
If you are having a medical emergency — or thoughts of harming yourself while stopping a medication — call 911, or call or text 988 (the US Suicide & Crisis Lifeline).

The description of stopping this drug is transcribed from its FDA-approved label; the taper guidance is general and true of these medicines as a class.
