What is Gabapentin?

Gabapentin is a medication 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 for dogs. Gabapentin requires a prescription from your veterinarian, and is sold per capsule.




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

How does Gabapentin work?

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 pets.

Talk to your veterinarian about any side effect that seems unusual or bothersome to your pet.

Gabapentin is rated 4.8 out of 5 by 10.
Rated 5 out of 5 by from Safe Pain Medication My dog takes this as part of her arthritis treatment. Between this and a couple of supplements, she is doing much better. Even though she still is sore and stiff sometimes, she's walking better.

Rated 4 out of 5 by from Wonder Drug, Frustrating Dosage Gabapentin does wonders for both dogs and humans, hands down. The problem is, the smallest available dose is 100mg capsules, and a 15 lb dog, according to two different vets, should have a daily dose of 75mg, spread throughout the day. You can't cut capsules. The price of compounding recently shot through the roof. I wish they would have a pet-sized dose.

Rated 5 out of 5 by from Without Gabapentin, my little girl could not sleep at night. There was a problem when ordering, but 188PETMEDS fixed everything & expedited the shipment without an additional charge. I am totally happy with this company and recommend to all my pet friends!

Rated 4 out of 5 by from A happy puppy again! My 8 month old mixed breed puppy was put on Gabapentin for pain. He has pinched nerves in his back and was in pain. Before going on meds he was unable to play too much and had a hard time jumping, running, even getting on couches, bed, etc. He has been on it for about 2 weeks now and is so much happier. He is a silly playful puppy again!

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.

My Corgi is 27lb and his vet prescribed him 200mg of Gabapentin every 8 to 12 hours. I read this websites and many others, and this dosage seems much higher than what's recommended. What do you think?

Asked by: TeamJackie
The recommended dose of gabapentin is 1.4 mg per pound once a day for pain and 4.5 mg-13.5 mg per pound every 8-12 hours for seizures. Doses may vary considerably depending on the pet's condition and other factors. Consult your veterinarian with your concern regarding your pet's dose.

I just noticedGabapentin my 10 lb chi takes. Stupidly I NEVER looked. It's 100 mg I'm flipping out. No wonder she gets tremors. How do I wean her off?? Please help, I can't believe this. It's for chronic pain.

Asked by: mommy
Thank you for your question. You will need to slowly taper the medication to prevent your pet from experiencing withdrawal symptoms. The specifics of the taper will depend on her current dosage and the amount of time she's been taking it. Please consult your veterinarian for guidance on how to taper your dog off the medication.

My cat was prescribed this drug for pain associated with kidney problems. I am now reading that it says make sure to talk to your vet if your pet has kidney disease. Takes only .2 ml twice a day. Is this a concern?

Asked by: DarDar
Thank you for your question. Gabapentin is a prescription medication for the treatment of seizures. It is also used to help with chronic pain. The medicaiton label warns simply to use Gabapentin with caution in pets with kidney disease. If the vet that prescribed the medicaition also diagnosed your pet with Kidney disease they should be aware of this caution. However for your peace of mind we recommend contacting your vet and discussing your concerns with them directly.

Asked by: Holly

How long does gabapentin take to start decreasing seizure activity. My dog has been having shivers like he's cold, sometimes barely visible, and the vet put him on this med. Yes it sedated him but there' no impact on the frequency or severity after 2 days

Asked by: DaniB3
Gabapentin may reduce the number of seizures and the time between seizures in dogs. Some patients may see improvement within 24 hours. Like humans, however, response to gabapentin therapy may vary widely. Consult your veterinarian regarding your concern for your pet.
