Are there better drugs for epilepsy than lamotrigine
There is no single "better" drug. The better drug depends on the epilepsy type, and lamotrigine is genuinely beaten in some of them.
For absence epilepsy in a child who already failed a first drug, ethosuximide is the better choice. In a randomized trial, 63 in 100 stayed free of treatment failure on ethosuximide at 16 to 20 weeks versus 45 in 100 on lamotrigine [1]. At one year it was 57 versus 36 in 100 [1]. Valproate worked about as well as ethosuximide but caused more attention problems [1].
For juvenile myoclonic epilepsy, levetiracetam beat lamotrigine. In a small retrospective study, 86 in 100 on levetiracetam stayed seizure-free past a year versus 29 in 100 on lamotrigine [3]. That study had only 28 patients, so treat it as a signal, not proof [3].
| Epilepsy type | Better drug | Lamotrigine |
|---|---|---|
| Childhood absence, second drug | Ethosuximide 63% [1] | 45% [1] |
| Juvenile myoclonic | Levetiracetam 86% [3] | 29% [3] |
| Idiopathic generalized (adults) | Valproate 71% response [4] | 40% [4] |
| Elderly, new-onset | No clear winner [2] | Ranks high [2] |
For adults with generalized epilepsy, valproate had the highest response rate, 71 in 100 versus 40 in 100 for lamotrigine [4]. But valproate carries its own serious risks, especially in pregnancy, and the records here do not quantify those [5]. In the elderly, no drug clearly won on seizure freedom, and lamotrigine ranked among the best for tolerability [2].
The honest gap: these are mostly small or observational studies, and none compares any drug to a true untreated group over years. Lamotrigine's main advantage is tolerability, not raw potency [2][6].
My call: switch away from lamotrigine for absence epilepsy (ethosuximide) or juvenile myoclonic epilepsy (levetiracetam), but keep it for older adults where it tolerates well. Confidence: moderate for absence, low for the rest.

Second monotherapy in childhood absence epilepsy
In children with childhood absence epilepsy who failed initial monotherapy, a randomized open-label second-monotherapy trial found ethosuximide and valproic acid more effective in maintaining seizure freedom and control than lamotrigine, with valproic acid linked to more attenti…

Antiepileptic drug monotherapy for epilepsy in the elderly: A systematic review and network meta‐analysis
In elderly patients with newly diagnosed epilepsy, antiepileptic drug monotherapies show no clear differences in seizure freedom at 6 or 12 months; lacosamide, lamotrigine, and levetiracetam rank highest for seizure control while carbamazepine formulations have poorer tolerabili…

The Tolerability of Lamotrigine in Elderly Patients With Epilepsy
This study evaluates the tolerability of lamotrigine in elderly patients with epilepsy by analyzing pooled data from 13 clinical trials, revealing that lamotrigine is well tolerated with a lower incidence of adverse events compared to carbamazepine and phenytoin.
