Gabapentin for Pets is a prescription medication that veterinarians use in dogs and cats to help manage chronic and neuropathic (nerve) pain, as an add-on for seizure control, and to ease situational anxiety before stressful events such as vet visits, travel, or grooming. Dispensed by Smarty Vets in 100 mg and 300 mg capsules, gabapentin works by calming overactive nerve signaling and is one of the most widely prescribed medications in veterinary pain management.
Key facts
- Active ingredient: gabapentin
- Species: dogs and cats
- Available sizes: 100 mg capsules (per capsule or 100-count bottle) and 300 mg capsules
- Form: oral capsule
- Typical uses: chronic and nerve-related pain (often alongside arthritis therapy), adjunct seizure control, and pre-visit anxiety, especially in cats
- Note: gabapentin is prescribed extra-label in veterinary medicine, so dosing is individualized by your veterinarian
How to use
Give exactly as directed by the prescribing veterinarian; the dose and frequency (often every 8 to 12 hours) depend on your pet's weight and the condition being managed. For anxiety around vet visits or travel, it is typically given a couple of hours before the event, as directed. If your pet has been on gabapentin long term, do not stop abruptly; your veterinarian will advise a gradual taper.
Safety information
The most common side effects are sedation and mild wobbliness (ataxia), which are usually temporary and dose-related. Pets with kidney disease may need reduced doses. Never substitute human liquid gabapentin formulations, which may contain xylitol, a sweetener that is toxic to dogs. Tell your veterinarian about all other medications your pet takes.
