Antiepileptic (sodium channel blocker)
Is Lamotrigine vegetarian or vegan-friendly?
Vegetarian and vegan patients sometimes ask whether their medication contains animal-derived ingredients. The active substance Lamotrigine in Lamotrigine is almost always synthetically produced; the question typically concerns excipients in the tablet or capsule shell at 25mg, 50mg, 100mg, 200mg.
Animal-derived excipients in Lamotrigine
Common animal-derived excipients in pharmaceuticals include gelatin (in capsule shells, derived from porcine or bovine sources), lactose (dairy-derived), and certain magnesium stearate sources. The prescribing information and patient leaflet for Lamotrigine list excipients; whether they are animal-derived is sometimes specified, sometimes left ambiguous. Lamotrigine is a phenyltriazine that selectively blocks voltage-gated sodium channels, stabilising neuronal membranes and reducing the release of excitatory neurotransmitters, particularly glutamate.
Practical guidance
According to general pharmacy practice, vegetarians and vegans concerned about Lamotrigine excipients should ask the pharmacist or manufacturer directly. Many medications have authorised generic versions with different excipient profiles — switching to a generic of Lamotrigine with vegetable-derived excipients is sometimes possible at 25mg, 50mg, 100mg, 200mg. For strict requirements (e.g. religious or strong ethical), specialist pharmacy consultation gives definitive answers.

For strict vegan requirements, confirm with the manufacturer or pharmacist for the specific Lamotrigine product.
