Calculation Methodology & Biological Principles
Dosing Formula Equation
Gabapentin modulates voltage-gated calcium channels in the spinal cord and dorsal root ganglion, decreasing central sensitization to pain signals.
Veterinary Disclaimer
Never abruptly stop long-term Gabapentin therapy, as withdrawal seizures can occur. Always follow your veterinarian's tapering plan.
Frequently Asked Questions
What is Gabapentin used for in dogs? ▼
Gabapentin is an anticonvulsant and neuropathic pain analgesic prescribed by veterinarians to treat chronic osteoarthritis, nerve pain, seizures, and situational anxiety in dogs.
What is the standard Gabapentin dosage for dogs? ▼
For chronic neuropathic pain, the typical starting dose is 5 mg to 10 mg per kg of body weight (approx 2.3 to 4.5 mg/lb) given every 8 to 12 hours. For seizures or severe anxiety, higher doses up to 10–20 mg/kg are used under veterinary supervision.
Is human liquid Gabapentin safe for dogs? ▼
NO! Liquid Gabapentin formulations made for human use often contain xylitol, an artificial sweetener that is extremely toxic and potentially fatal to dogs. Only use oral capsules or veterinary-compounded xylitol-free liquid.
