Series Pain Management in dogs: Gabapentin
Gabapentin was originally developed as an anticonvulsant drug but it too can be an effective component of chronic pain management. It has been shown to be particularly effective in neuropathic pain management (pain from direct nerve injury) and cancer related pain.
Gabapentin is useful for both dogs and cats. It is generally free of adverse effects or adverse drug interactions although some patients will show some drowsiness usually limited to a few days. Dogs are typically dosed at 5 to 10 mg/kg BID to QID PO although doses as low as 2 mg/kg BID have been reported to be effective in some cases while doses as high as 120 mg/kg/day have been required in other cases. Cats are typically dosed at 2 to 10 mg/kg BID PO.
Gabapentin may potentiate the sedative influence of other medications. Withdrawal of this drug should be done gradually to avoid rebound pain.
