Gabapentin for Dogs | Wag!

Jump to section

Gabapentin is an anticonvulsant originally created as a treatment for epilepsy in humans. Over time, clinical application revealed gabapentin was also successful in “off-label” uses such as the treatment of nerve pain and mood disorders in humans and canines.

Anticonvulsants like gabapentin work by influencing neurotransmitter activity and changing how the brain interprets information from the body. Gabapentin isn't a cure for these conditions, but for many dogs, it significantly increases their quality of life.

Dosage

Gabapentin comes in three forms: capsules, tablets, long-acting tablets, and oral solutions. To calculate a starting dose of gabapentin, vets consider the animal's kidney function, age, size, medical issues, and the bioavailability of the brand. An average starting dose of gabapentin for dogs ranges from 3 mg to 20 mg per kg twice daily. Owners may offer this medication with or without a meal.

Efficacy

One study of gabapentin for dogs with epilepsy found it decreased seizure activity in half of the test subjects. A study on felines published by the American Veterinary Medical Association found that gabapentin helped control anxiety and compliance before stressful events.

Clinical data supporting gabapentin's analgesic effects in canines is limited; however, there's much anecdotal evidence of its pain-relieving properties for dogs. A study of postoperative pain levels in canines found that this medication boosted the effectiveness of nonsteroidal anti-inflammatory drugs (like ibuprofen) and vice versa. The dogs given gabapentin required fewer doses of narcotic painkillers than those who were given NSAIDs alone.

Frequently asked questions

What should I do if my dog misses a dose of gabapentin?

Never double up doses of gabapentin to make up for a missed dose. Many vets and doctors follow the 2-hour rule for oral medications. If you realize you've forgotten your dog's meds within 2 hours of the missed dose, you can give go ahead and it to them. If it's nearly time for the next scheduled dose and your pet isn't exhibiting signs pain or epileptic activity, then continue their dosage at their regular time.

How do I know if gabapentin is managing my dog's pain?

Most dogs hate taking pills — unless they're flavored, of course. Make things easier for you and your pup by hiding their meds in a piece of cheese, meat, or flavored "pill pouch".
