Lamictal and if you taper off it can it cause siezures and death for eplipsy

Yes. Stopping lamotrigine in someone with epilepsy can bring seizures back, and a bad seizure can kill. That is the real risk, and it is why you taper slowly with a doctor rather than quit.

The records don't include a study of lamotrigine withdrawal in epilepsy. What they do show is that the drug is doing real work: in newly diagnosed epilepsy, lamotrigine held seizure control about as well as carbamazepine and phenytoin over 48 weeks [2], and 75% of 91 patients followed up to 107 weeks stayed seizure free [2]. Take that away and the seizures it was suppressing can return.

The death risk is not the taper itself. It is what an uncontrolled seizure can do. In a 30-year cohort of teenagers with epilepsy, 4 patients died and 3 of those were probable sudden unexpected death in epilepsy (SUDEP), all in people whose seizures were uncontrolled [3]. That is the mechanism that makes abrupt withdrawal dangerous.

One twist worth knowing: lamotrigine can also make seizures worse in certain rare epilepsy syndromes. In 21 children with severe myoclonic epilepsy, 17 got worse on the drug [1], and one child with Lennox-Gastaut developed myoclonic status epilepticus after a dose increase, which resolved when the drug was stopped [4]. So for a few patients, stopping is the safer move, not the riskier one.

SituationWhat the evidence shows
Lamotrigine vs older drugs, 48 weeks [2]No significant difference in seizure recurrence
Seizure-free on long-term lamotrigine [2]75% of 91 evaluated
Deaths in teen epilepsy cohort [3]4 total, 3 probable SUDEP, all uncontrolled
Worsening on lamotrigine, severe myoclonic epilepsy [1]17 of 21

My call: taper slowly under medical supervision, never stop abruptly, and treat any returning seizure as urgent. Confidence: moderate that withdrawal raises seizure risk, low on the exact taper schedule, because no study here tested one.
