Lamotrigine: what pharmacies actually pay

Prices below are the National Average Drug Acquisition Cost (NADAC) — the federal government's weekly survey of what pharmacies actually pay their wholesalers, as of 07/22/2026. Your pharmacy's cash price includes their markup and dispensing cost, so it will be higher — but if it's many times this number, that's a signal to shop around.
