Is Neurontin vegetarian or vegan-friendly?
Vegetarian and vegan patients sometimes ask whether their medication contains animal-derived ingredients. The active substance Gabapentin in Neurontin is almost always synthetically produced; the question typically concerns excipients in the tablet or capsule shell at 100mg, 300mg, 400mg, 600mg, 800mg.
Animal-derived excipients in Neurontin
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.

Practical guidance
According to general pharmacy practice, vegetarians and vegans concerned about Neurontin excipients should ask the pharmacist or manufacturer directly. Many medications have authorised generic versions with different excipient profiles — switching to a generic of Gabapentin with vegetable-derived excipients is sometimes possible at 100mg, 300mg, 400mg, 600mg, 800mg. For strict requirements (e.g. religious or strong ethical), specialist pharmacy consultation gives definitive answers.
