What is Gabapentin?

Gabapentin is a medication for dogs and cats for the treatment of seizures. It is also used to help with chronic pain. Although Gabapentin is not FDA-approved for use in veterinary medicine, it is a commonly accepted practice for veterinarians to prescribe this medication. Gabapentin requires a prescription from your veterinarian, and is sold per capsule.

How it Works:

Gabapentin stabilizes electrical activity in the brain which prevents seizures caused by excessive electrical activity. Gabapentin mimics the activity of GABA (a neurotransmitter) which helps to calm the nerve activity in the brain.
