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.

Key Benefits

  • Medication for the treatment pain, especially chronic pain
  • Gabapentin can also be used to treat seizures
  • Available in two prescription strengths in tablet or capsule form

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.


Weight Dosage
all weights

For seizures: 4.5 mg-13.5 mg per pound every 8-12 hours.

For pain: 1.4 mg per pound once a day.


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


Because gabapentin is almost completely eliminated from the body by the urinary tract and kidneys, it should be administered with caution in animals with kidney disease.


Should be stored at room temperature, away from moisture and light.


Gabapentin is a prescription medication not FDA approved for veterinary use; however, it is a commonly accepted practice for veterinarians to use this medication in dogs. Gabapentin is available as 100 mg, 300 mg, and 400 mg capsules. The usual dose to treat seizures in dogs is 4.5 to 13.5 mg per lb every 8 to 12 hours. As an aid in chronic pain treatment or cancer pain in dogs, the usual dose is 1.4 mg per lb once a day.
Tell your veterinarian if your pet has kidney disease. The dose of Gabapentin may need to be adjusted. Unless the benefit outweighs the risks do not use Gabapentin in pregnant or nursing pets.
Give this medication exactly as directed by your veterinarian. If you do not understand the directions ask the pharmacist or veterinarian to explain them to you. Do not give antacids within 2 hours of giving Gabapentin. Antacids can affect Gabapentin blood levels. Drug interactions may occur when giving any narcotics such as hydrocodone or morphine. Do not suddenly stop the use of Gabapentin. Store Gabapentin at room temperature away from moisture and heat. Keep this medication away from children.
If any of the following serious side effects occur, stop giving Gabapentin and seek emergency veterinary medical attention: an allergic reaction (difficulty breathing; swelling of the lips; tongue or face; hives). Side effects that can occur in dogs may include drowsiness, loss of balance, swelling of the limbs, and vomiting or diarrhea. Talk to your veterinarian about any side effect that seems unusual or bothersome to your pet.
Give the missed dose as soon as you remember during the same day. However, if you don't remember until the next day, skip the dose you missed and give only the next regularly scheduled dose. Do not give a double dose of the medication.
Seek emergency veterinary medical treatment. Symptoms of Gabapentin overdose include reduced activity, excessive sleepiness, loss of balance, and depression.
Gabapentin should not be used in pets allergic to it. Do not use in pregnant or nursing pets. Use with caution in pets with kidney disease. Do not give antacids within 2 hours of giving Gabapentin. Consult your veterinarian before giving any narcotic such as hydrocodone or morphine since drug interactions can occur.
Tell your veterinarian if your pet is being given antacids or narcotics for pain. Drugs other than those listed may also interact with Gabapentin. Talk to your veterinarian or pharmacist before giving any prescription or over the counter medicines including vitamins, and supplements.

Outstanding pain relief
December 4, 2020
My little girl Zoey ( a Lhasa apsa mix)is 13 with arthritis and suffers with pain in her legs that she will lick her paws raw and pull her hair out to try to get to the pain. The vet ordered gabapentin and it was a life saver. We are so happy now. I am very happy with the prices of entirely pets pharmacy and the friendly customer service

Merchant Response:Zoe is adorable. Wishing you both the best

Sadly prices outweighs their customer services. Never get your order timely not even the n auto ship. Be aware you take the risk of having your loved pets in medicated for awhile. I mean is so terrible but because of the incredibly low price one puts up with them. Not right? Yes! If you donít have excess money and care for your pets, have no way out and So Entirely pets do know how to take advantage of it.
