Gabapentin is an anti-seizure medication that has good relief of chronic neuropathic pain.

This drug is occasionally used in management of osteoarthritis or immune-mediated arthritis in dogs.

Recommended dose is 5 - 10 mg/kg orally twice daily, though lower doses and frequency can be used if excessive sedation occurs.

The dose can safely be increased as needed (usually by 25 - 50% every 7 - 14 days) until an effective level is reached.
