Thank you for providing Cooper's weight in your question, it's very helpful in answering! In veterinary medication, Gabapentin has many uses, such as treating seizures, pain, and anxiety. For example, if we were to use Gabapentin to treat anxiety, it can be used in a dose range of 5-30mg/kg up to three times daily. If he is 30 pounds, that's about 13.6kg. If we dosed him at the max of 30mg, that would be 409mg of Gabapentin he would be allowed to have at one time. This means that the amount he ingested (300mg) is a safe amount for him to have, but I expect that he will likely be very sleepy from this pill. I hope this helps!

My dog was prescribed 600mg/day of Gabapentin as an adjunct to Meloxicam for arthritic knee pain. I read that 1.4 mg per pound of weight is the standard dose for dogs for pain. 600 mg seems excessive. What in your opinion is the standard dose for
Thank you for contacting Boop by Petco with your question about Jack. For pain control in dogs, the dose can go as high at 5mg per pound, which would be 450mg. But it can be used up to 10mg per pound for dogs with seizures, so this isn't an overdose. It may be he needs the extra pain control. but I would speak to your vet about your concerns. Best of luck.

9 week old puppy just ate adult dog's 300mg gabapentin pill. Should I be worried?
Gabapentin has quite a large safety margin, the maximum dosage is about 15mg per pound but even a higher dosage for a one time ingestion is not likely to cause any severe side effects. how much does you puppy weights?

15 yr old Jack Russell takes 100mg gabapentin 2x every day. Took 3x today by accident. She is 28 pounds. Will she be okay?
Yes, this should be just fine. Gabapentin is frequently dosed three times daily in many dogs, so this isn't uncommon at all. It also has a very high margin of safety, so I wouldn't expect to see any problems unless she ingested the entire bottle at once :) She may be a bit more drowsy than usual, but otherwise should be fine.

What will happen if our 65lb pit bull ate 9 - 300mg capsules of Gabapentin?
Thank you for using Boop by Petco! The dose Peanut ingested is about three times the upper end of the daily dose for a dog his size. Gabapentin commonly causes signs such as lethargy and difficulty moving/disorientation. Peanut may need supportive care such as fluids, administered by a veterinarian if he develops these signs. In the meantime, I recommend keeping a very close eye on him, and having him seen by a vet right away if he develops the signs above. I hope all is well!

My Corgi is 27lb and his vet prescribed him 200mg of Gabapentin every 8 to 12 hours. I read some websites, and this dosage seems much higher than what's recommended. What do you think?
Hello. The range of dosages of Gabapentin used for analgesia in dogs is 10-20 mg/kg every 8 hours. For a 27 pound dog, this equals 123 - 245 mg every 8 hours. When used as an anticonvulsant, doses up to 1200 mg are sometimes used. If you are concerned, start with the 200 mg every 12 hours, adding a third dose if necessary. Thank you.

Thank you for submitting your question regarding Mia. Gabapentin has a very wide dosing range. The amount given will likely make her sedate, but should not cause her any long lasting harm. Give her next dose back on schedule if she is not too groggy. If so, you can wait an extra hour or two to give it more time to wear off. I hope this information helps!

Hello is it safe for a 18kg dog with terminal cancer to take 800mg of gabapentin each day?
That is a very high dose if given all at once, it is 1.5 times the maximum recommended dose. 800mg spread out through 3 or 4 doses would be good. If your pet is in pain, gabapentin may not be enough. You should discuss a multi-modal pain protocol with your vet, often adding in steroids, NSAIDs, opioids, acupuncture, laser therapy, etc will be better than a single medication.

Hi, no this is the dosage we use for a standard weight cat to make them a bit drowsy and less anxious to go and see the vet, it normally works very well ! It sounds a lot but it is what we normally give. Hope this helps and that it works well for you too.

My 12 week old Rottweiler puppy may have ingested a 600 mg gabapentin tablet. He weighs about 21 lbs. Do I need to find an emergency vet?
That is nearly 6 times the dose for his size, I would seek out emergency care from your vet or clinic right away. You can also contact the Pet Poison Helpline - https://www.petpoisonhelpline.com/ - (there is a fee for this service) for more information, however, if he is showing any signs of illness (extreme lethargy, confusion, vomiting, diarrhea, etc) seeking care right away is best.

Can I give my 15# Shih Tzu dog 100mg gabapentin for his arthritis?
That's a pretty high dose for a dog his size and may cause sedation. Gabapentin is a great medication for arthritis, but I'd start with about half that dose, and I'd recommend running it by your primary veterinarian to make sure it's appropriate with Obi's medical history and any other meds he might be taking. I hope this helps!
