Is gabapentin safe for dogs?

Gabapentin is safe for dogs and is commonly prescribed by veterinarians to treat seizures, pain, and anxiety in dogs. It has a low risk of side effects.

What is gabapentin used for in dogs?

Gabapentin can treat and reduce the frequency of seizures and is commonly used as an anticonvulsant to treat or prevent seizures in dogs.

Gabapentin may also be used to provide pain relief for dogs, particularly when other medications have proved ineffective or are not well tolerated. It may be used to treat pain associated with cancer, arthritis, or intervertebral disk disease.

Gabapentin is commonly used as a mild sedative to treat situational anxiety, for example, just before a vet visit.

Using gabapentin in pets is considered “off-label” which means it is not an FDA-approved indication in pets.

How does gabapentin work in dogs?

Experts aren’t sure exactly how gabapentin works to relieve seizures, pain, or anxiety but it is thought to inhibit the release of excitatory neurotransmitters. Gabapentin resembles a naturally occurring inhibitory neurotransmitter called GABA (γ-aminobutyric acid), which is involved with the transmission of nerve signals within the brain and spinal cord.

How much gabapentin should I give my dog?

Dosages of gabapentin for dogs can vary, but usually, gabapentin is dosed at 5 to 30 mg/kg (or 2.2 to 13.6mg/lb) up to three times daily.

Gabapentin can also be given before an anticipated stressful event, such as a veterinary visit, at a dose of 30-60 mg/kg one to two hours before the event.

How long does gabapentin take to work?

Gabapentin is quick acting, and an effect should be noticed one to two hours after administration. However, when gabapentin is used to treat pain, a low dosage is started initially, which is then titrated up slowly, which means it may take longer to see an effect. While your vet is titrating up the dosage, they will be using other medications to keep your dog comfortable until the gabapentin is working. When used to treat seizures gabapentin may take a few weeks to reduce seizure frequency.

The effects of gabapentin wear off quickly unless the dog has kidney or liver disease. This is why it is usually given three times a day.

What are the side effects of giving a dog gabapentin?

The most common side effect of gabapentin in dogs is drowsiness, which can be managed by starting with a low dosage of gabapentin and increasing it slowly. Most dogs become tolerant of this side effect with continued dosing.

When starting gabapentin your dog may also seem a little uncoordinated initially, but this should also resolve with continued dosing. Rarely, a dog may be allergic to gabapentin and they may have a reaction which is a sign to avoid giving gabapentin to your dog in the future.

Xylitol is used to sweeten commercially prepared gabapentin oral suspension and this can be toxic to dogs. Low-to-moderate dosages of gabapentin oral suspension are unlikely to contain enough xylitol to be problematic for dogs but higher dosages, such as those used for seizures, might. This can be avoided by having liquid formulations compounded rather than using the commercially available oral suspension.

How does gabapentin make a dog feel?

Gabapentin makes your dog feel a little sleepy and possibly a little uncoordinated initially. They should become tolerant to these effects within a few days, especially if the dosage is started low and titrated up slowly.

Can gabapentin cause hind leg weakness in dogs?

Hind leg weakness may be a sign of incoordination in dogs, usually associated with too high a dose of gabapentin. If your dog has been on gabapentin a long time and this happens, tell your veterinarian. As pets age, their bodies are not as efficient at metabolizing gabapentin and side effects, such as incoordination may reappear again, especially hind leg weakness. Usually reducing the dosage helps resolve this.

Can I overdose my dog on gabapentin?

Although gabapentin is generally well tolerated in dogs, like any medication, you can give too much of it. Always follow your vet’s instructions and never try to increase the dosage yourself without their advice.

Symptoms of an overdose of gabapentin in dogs include diarrhea, extreme sleepiness, lethargy, and incoordination; however, an overdose is not usually fatal. Seek veterinary advice immediately.

What can I give my dog instead of gabapentin?

Gabapentin is commonly used to treat nerve pain in dogs but there may be times when a dog does not tolerate it or it no longer effectively treats the pain. Other treatments that may be effective for nerve pain in dogs include:

• Pregabalin (Lyrica): this works similarly to gabapentin but it lasts longer which means it only needs to be given twice a day and it is more effective at a lower dosage
• Amantadine works by blocking NMDA receptors in the spinal cord and may improve your dog’s mobility when used in addition to NSAIDs

Other possible treatments that require more research include amitriptyline and venlafaxine.
