What Is Gabapentin?

Gabapentin is considered an off-label prescription medication. This means gabapentin for dogs and cats has not been approved by the FDA, however, gabapentin has been approved by the FDA for a wide variety of uses in people. At the same time, gabapentin is frequently prescribed as an anxiety treatment and seizure treatment, and it is generally well-tolerated when monitored by a trained veterinarian.

Additionally, gabapentin can be particularly useful as a treatment for nerve pain. If this type of pain is not controlled with other pain medications, gabapentin can be prescribed. There are even some situations where a trained veterinarian may prescribe gabapentin with other medications. It could play a role in a well-rounded treatment strategy for the treatment of pain, arthritis, anxiety, and other medical conditions.

Gabapentin goes by a wide variety of other names, including, Neurontin, Gantin, Gaborone, Neurostil, Horizant, and Progresse.1 It is important for any pet owner interested in gabapentin for cats to talk to their veterinarian about whether it’s a good option for their pet.1

Uses of gabapentin for cats

Gabapentin For Cats: Uses

There are several common situations where a veterinarian may recommend gabapentin as a treatment option for a cat. Some of the most common uses and applications of gabapentin in cats include:1

Anxiety Management

Gabapentin can be an effective option as a cat anxiety treatment. There are a lot of cats who suffer from anxiety, particularly those who have a traumatic history. Pet owners may have a difficult time managing cat anxiety, and gabapentin can be helpful. Right now, researchers believe that gabapentin helps treat anxiety by increasing inhibitory neurotransmitters in the brain, such as GABA. That way, cats and dogs have a much easier time relaxing, and pet owners can effectively manage anxiety symptoms.

There are several signs that could indicate that your cat is suffering from anxiety. You may feel like your cat is not as sociable as he or she used to be. You may also notice your cat is hiding more often than before. If you feel like your cat is a bit skittish, he or she could be suffering from anxiety.

If you feel like your cat is suffering from anxiety, schedule an appointment with a veterinarian to see what your treatment options for anxiety are. There is a chance that your veterinarian may prescribe gabapentin as a way to treat anxiety in your cat.

Seizure Prevention

Another common reason why a veterinarian may prescribe gabapentin is as a method of seizure prevention and control. There are a lot of reasons why cats may develop seizures. There are some situations where cats may suffer from epilepsy, and there are other situations where cats may have an electrolyte imbalance. There are even situations where brain tumors could cause cats to develop seizures. In this situation, a veterinarian may use gabapentin to help prevent future seizures from happening.

Seizures can present in a variety of ways in cats. For example, your cat may suffer from seizures that involve all four extremities shaking at the same time. Or, your cat may simply stare off into the distance. If you are wondering whether your cat is suffering from seizures, you may want to reach out to your veterinarian to schedule an appointment. Your veterinarian may run a few tests to see if your cat suffers from a condition that could cause seizures. Then, your veterinarian may prescribe gabapentin as a treatment option.

Pain Control

Veterinarians may also decide to use gabapentin as a method of pain control. In this role, gabapentin blocks calcium channels throughout the central nervous system. That way, neurons that are typically stimulated by pain will no longer be stimulated. As a result, gabapentin can be a useful choice in the treatment of joint pain, arthritis, and numerous other pain types. Even though gabapentin can be used to address neuropathic pain in humans, there is more research that has to be done before deciding whether gabapentin can do the same job in pets.

These are just a few of the most common applications of gabapentin. It has become a very common treatment option for a wide variety of conditions. Working directly with your vet is the best way to find a treatment solution for your pet’s needs, whether they need medication prescribed or would benefit from implementing some basic lifestyle changes.

Fatigue and Tiredness

One of the most common gabapentin side effects for cats is sedation. Fatigue and tiredness can be common when using gabapentin. The level of drowsiness typically depends on how the cat reacts to the drug. Just as people react differently to medications, cats can react differently to gabapentin as well.

Cats may also get a bit more excitable when they take gabapentin. For example, they may get startled more easily when they take this medication. Pet owners should expect their cats to be a bit more on edge when they start taking gabapentin.


G.I. complications are not unusual with gabapentin, and pet owners may realize that their cats have diarrhea when they take gabapentin. Pet owners should make sure that their cats have access to the litter box when taking this medication.

Increased Appetite

Pet owners may also realize that their cats are eating more when they take gabapentin. Pet owners should make sure that they do not overfeed their cats, particularly when they take this drug.


You may even notice that your cat sleeps more often than before. Even though cats already sleep a lot, you may see your cat around a bit less while giving gabapentin. If your cat spends a lot of time sleeping, understand that this could be a side effect of the medication. At the same time, you should reach out to your veterinarian with any questions or concerns.

Even though there are other side effects that might be a bit less common, side effects with gabapentin are relatively rare.

Pet owners should also reach out to their local veterinarian with any questions or concerns they may have.

Gabapentin doses for cats

Gabapentin For Cats: Dosage

Just like other medications, gabapentin's dosage can vary significantly from cat to cat. That is why a lot of veterinarians use a gabapentin for cats dosage chart. This dosage chart is important for making sure cats are not overprescribed gabapentin. Similar to other medications, dosing is usually determined by weight.

Keep in mind that the dosage may need to be increased or decreased depending on how the cat responds to the medication. If the cat does well on gabapentin, then the medication might be scaled back if the condition is appropriately addressed. On the other hand, if the cat is not responding appropriately to the medication, then a higher dose might be needed to provide an effective treatment option.

Additionally, pet parents should be aware that there is also a small chance that your cat could be allergic to gabapentin. That is why veterinarians will encourage you to keep an eye on your cat to make sure he or she does not develop an acute reaction immediately after taking the medication. If your cat is allergic to gabapentin, then you should avoid this medication and contact your vet immediately if allergy symptoms arise.

Gabapentin is prescribed in a variety of doses. They include:

  • 100 mg capsules and tablets
  • 300 mg capsules and tablets
  • 400 mg capsules and tablets
  • 800 mg capsules and tablets

These doses can vary significantly, and your veterinarian will work with you to find the right dosage for your cat depending on his or her weight. In general, this is a medication that is prescribed about once every 8 hours by mouth. You can choose to give this medication to your cat either with or without food. It is critical for you to follow the directions provided by your vet closely. That way, you make sure that you give the medication to your cat safely.

Before you leave your vet's office, you need to make sure you understand exactly how to give medication to your cat. Your vet should tell you what the dosage is, how often you need to give the dose to your cat, how to administer the medication, and what you need to watch for. The frequency, administration, and quantity of the dose is going to depend on the weight of your cat and why your cat is receiving the medication.

If you are wondering how to get your cat to take the medication orally, there are a few options available. You may want to start by burying the pill in your cat's food. That way, when your cat eats the rest of his or her food, he or she will also eat the medication. You may have an easier time doing this if you give your cat wet food. That way, your cat may not get a chance to uncover the medication before he or she swallows it. If you put the medication in a bunch of dry food, your cat may notice it before eating it. Then, your cat could eat around it.

Another option is to consider wrapping the pill or capsule in something delicious. If you decide to wrap the medication and food, you need to talk to your veterinarian to make sure whatever you wrap the pill in will be safe for your cat. Your veterinarian may also have some recommendations about what type of food you should use.

There are lots of cat owners who give their cats gabapentin regularly, and your veterinarian will work with you to figure out the best method to give gabapentin to your cat as well.
