Used for Epilepsy, Postherpetic Neuralgia
Gabapentin (Neurontin) is an FDA-approved human medication commonly prescribed off-label by veterinarians, along with other medications, for cats and dogs to manage anxiety during events like vet visits and to treat chronic pain, such as arthritis. Although gabapentin is considered an anti-seizure medication, it’s not typically used on its own to treat seizures in cats or dogs. Instead, it might be prescribed in combination with other medications to control symptoms. Since the dose is based on your pet’s weight, your veterinarian will help to determine the right dose. Common side effects include sleepiness, tiredness, and difficulty with walking and balance.
