Key points

  • Lamotrigine can cause serious skin reactions, with risk shaped by starting dose, how quickly the dose is raised, and co-medications such as valproate.
  • In Mental Health, lamotrigine is used for maintenance in bipolar I disorder, not for an acute mood episode.
  • As an anticonvulsant, lamotrigine reduces abnormal electrical activity in the brain.

Common questions about Lamotrigine

What separates Lamictal from Lamictal Dispersible?

Both are GlaxoSmithKline products containing the same active ingredient. The difference is in how the tablet is taken: Lamictal Dispersible is designed to dissolve in water or be sprinkled on soft food, while the regular tablet is swallowed whole. The choice between them comes down to swallowing difficulty, not to a difference in how the medicine works.

What strengths are listed for each formulation?

Regular Lamictal tablets cover 25 mg, 50 mg, 100 mg and 200 mg. Lamictal Dispersible is listed at 50 mg and 100 mg. Both formulations are indicated for epilepsy and bipolar I disorder maintenance.
