⚠ Medical warning
Don’t stop this medicine suddenly or cut your dose on your own. Its FDA label says Keppra should generally be withdrawn gradually because of the risk of more frequent seizures and status epilepticus. Only stop with your prescriber’s plan. Call 911 for a seizure that lasts more than 5 minutes or for repeated seizures.
Quick answer
Keppra (levetiracetam) treats seizures. Its FDA label says to avoid abrupt withdrawal to reduce the risk of increased seizure frequency and status epilepticus (a prolonged, dangerous seizure), and that it should generally be withdrawn gradually. Its half-life in adults is about 7 hours, so levels drop quickly after missed doses. The NHS says if your doctor advises stopping, your dose will usually be reduced gradually.

Symptoms, phase by phase
The Keppra label’s warning on withdrawal seizures says that, as with most antiepileptic drugs, Keppra should generally be withdrawn gradually because of the risk of increased seizure frequency and status epilepticus. The label doesn’t describe other withdrawal symptoms. Evidence note: the risk when stopping is mainly seizures returning or worsening; there isn’t a well-defined withdrawal timeline.
Missed doses or sudden stop: Within a day or so (short half-life; timing varies)
- Breakthrough seizures
- More frequent seizures
During a supervised taper: Over the period your prescriber sets
- Watch for any return of seizures
After stopping: Ongoing
- Seizures may return if the epilepsy is still active
What makes withdrawal longer or shorter
- Seizure history. People with active epilepsy are at most risk.
- Speed of stopping. Abrupt stops carry the highest risk.
- Half-life. About 7 hours in adults, so missed doses matter quickly.
When to see a doctor or get help now
- Before stopping or changing your dose.
- Call 911 for a seizure lasting more than 5 minutes or repeated seizures; the NHS gives these as reasons to call for emergency help.
- If you’ve run out, contact your prescriber or pharmacy the same day.
- Call or text 988 for thoughts of suicide.

Tapering
The FDA label says Keppra should be withdrawn gradually, and the NHS says your dose will usually be reduced gradually if your doctor advises stopping. 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
- Never let your prescription run out
- Keep a seizure diary
- Tell family what to do if you have a seizure
- Ask your doctor about driving rules while tapering
Frequently asked questions
What happens if you stop Keppra suddenly?
The label warns of more frequent seizures and status epilepticus.
Can Keppra be stopped if I’ve been seizure-free?
Only your neurologist can judge that and plan a gradual withdrawal.
I feel moody on Keppra. Can I just stop?
Don’t stop on your own. The label notes behavior and mood changes can occur; tell your prescriber, who can adjust your treatment safely.
