⚠ Medical warning
Don’t stop lamotrigine (Lamictal) suddenly. The FDA label warns of seizures, including in people taking it for bipolar disorder, and of life-threatening status epilepticus in epilepsy. Talk to your prescriber first, and call 911 for a seizure.
Quick answer
The Lamictal label says lamotrigine should not be stopped abruptly, as with other seizure medicines, and that it should be tapered over at least 2 weeks unless safety requires a faster stop. In bipolar disorder trials, 2 patients had seizures shortly after abrupt withdrawal. If you’ve missed several days, don’t just restart your old dose: lamotrigine usually needs to be restarted slowly because of rash risk, so call your prescriber.

Symptoms, phase by phase
Lamotrigine doesn’t have a well-described withdrawal syndrome like benzodiazepines. The main risks of stopping suddenly are seizures (including in people without epilepsy, based on the 2 bipolar-trial cases in the label) and the return of the condition it treats. The label also says that in controlled bipolar trials there was no increase in the incidence, type or severity of adverse reactions after abrupt stopping, apart from those seizure reports.
After a sudden stop: Days after stopping (the label gives no specific timeline)
- Return of the condition it treats (seizures or mood symptoms)
What makes withdrawal longer or shorter
- Epilepsy. The label warns of status epilepticus or severe seizures, which may be life-threatening.
- Other medicines. Starting or stopping medicines like valproate, carbamazepine or birth control pills can change lamotrigine levels.
- Restarting. Restarting after a break may need a slow re-titration because of rash risk.
When to see a doctor or get help now
- Before you stop or change your dose.
- If you’ve missed doses for several days, before restarting.
- Call 911 for a seizure, hallucinations, severe confusion, a high fever or trouble breathing.
- Call or text 988 for thoughts of suicide.

Tapering
The label says to taper over at least 2 weeks unless safety requires a faster stop. 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
- Use a pill organizer or phone alarm
- Keep a seizure and mood diary
- Tell your prescriber about any new medicines, including birth control

Does lamotrigine cause withdrawal symptoms?
It isn’t known for a classic withdrawal syndrome, but abrupt stopping can trigger seizures.
I missed a few days. Can I restart my usual dose?
Call your prescriber first; you may need to restart lower.
