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.


Dogs and Cats

  • Treats seizures
  • Helps manage chronic pain often associated with cancer or arthritis
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.


Unless the benefits outweigh the risk do not use Gabapentin in pregnant or nursing animals.

Gabapentin is rated 5.0 out of 5 by 5.
Rated 5 out of 5 by from Good for pain My elderly Am Staf has thyroid disease, Addison's disease, and blew out his back left knee. We tried rehabbing with a brace, as he does not do well with anesthesia. but it did not go well. So now he limps and favors the leg frequently. The gabapentin is for his pain and it does seem to making walking easier for him and he doesn't limp as much.

Rated 5 out of 5 by from Great Product for Dancing Doberman Disease Dancing Doberman is a Neurological problem that effects a Doberman's back legs. Tremors and leg movement are going on constantly making the dog constantly restless. My Doberman has been on Gabapentin since she was diagnosed at age 7. The Gapapentin has helped to slow the tremors and give her a lot more peace so she is not so restless. Great product for a disease that is not that well known.

Rated 5 out of 5 by from Very helpful My 13year old schnauzer has Cushing's disease , hip dysplasia and an under active thyroid.About 4 months ago I noticed she had problems lying down and she regularly wanted breakfast in bed! Hip dysplasia was diagnosed. She was on symmetrel for a time but it made her vomit. She was put on gabapentin and it immediately made a difference. She has also had tramadol for bad days, changing to metacam or previcox after seeing specialist, but she rarely needs them. The gabapentin is very helpful to her and she can happily continue her hour long walks.

Rated 5 out of 5 by from Positive Quality of Life Benefits Jack is my aging 9 year old greyhound rescue. I adopted Jack when he was 2 years old. He is now showing signs of arthritis and possible canine dementia. It's been a year of veterinary care, specialists, and emergency room visits. Jack would not settle down at night, he was loosing weight, he would pant from pain and seemed anxious. Understand that all of his physiological tests results were normal. These tests included: ultra sounds, blood, urine and X-rays. Even vet specialists were stumped by Jack's symptoms. Rimadyl was the best we could come up with as an answer to Jack's pain. It just didn't help him at night with his sleeplessness and anxiety. Jack's vet and I decided to try Gabapentin to help Jack sleep and aid in his pain relief. The very first time Jack took his Gabapentin he calmed down at night and slept through the night. Jack was up and alert the next morning. We are continuing the Rimadyl along with the Gabapentin. Perhaps more vets should look at Gabapentin for the relief of some of the symptoms of canine dementia and arthritis due to aging. This drug has been life altering in a positive way for my precious 9 year old greyhound, Jack.

Rated 5 out of 5 by from Awesome for seizures/anxiety/pain My 12 year old dog started having episodes of "fly biting" and apparent visual disturbances that would lead to excessive anxiety, panic, panting that would make me nervous watching it and I felt helpless. Knowing the effectiveness of Gapabentin (having used it myself) I insisted on this anti-seizure med to be tried first (once my vet determined seizures were likely the problem). My dog is 50lbs and the vet rx'd 200 mg 3x's per day - WAY TOO MUCH to start. This medication must be increased very slowly, starting w/100mg once per day until you notice the next dose needs to be started. It worked so well and immediately that 100mg worked well for a few weeks, when she showed signs of symptoms, I added the 2nd dose and so on. Now that she is on a therapeutic dose (over a couple months of slowly increasing the dose) about 400mg per day it has helped relax her and works great. It has helped everything including pain in her hips and knee to a degree that is noticeable. I give her the small capsule in a small clump of Gerber or beechnut baby meats - she doesn't even know it is in there and swallows it whole without chewing. I recommend trying this medication before any other anti-seizure medication that has the potential (that gabapentin does NOT) to change personality in a dog, make them aggressive,etc. Try this first! Worked well for me and my dog too, without any personality changes as I knew it would! This medicaiton is under used in pets and not well known, I hope more vets realize what a great medication this is.

RX question

I have a 70# Lab/Retriever. He's on 97.2 mg of Phenobarbital per day. Can he also take Gabapentin for back leg pain? If so, what dosage is recommended?
Asked by: Devildog
You would need to consult with your veterinarian about this. Since I do not know this dog's history and assuming he is being given Phenobarbital for seizures, adding Gabapentin would have to be discussed with your vet. Also, the dose would need to be determined by your veterinarian since the dose can vary between the severity of pain your pet is having.Thanks for your question.

Mode of dosing Gabapentin?

My jack Russell terrier has been on Gabapentin 26 mg by mouth twice daily for arthritic pain. This was dispensed by a compounding pharmacy. The cost is too much! Could I take the 100 mg capsule and withdraw 1/4 of the liquid with a syringe?

Is carprofen/gabapentin combo effective for canine arthritis?

Asked by: chowmix
The carprofen is effective for arthritis; however, the gabapentin is used for nerve pain and will most likely not be effective for arthritic pain.
