How this Medication is Used
Gabapentin can be used in both dogs and cats. The dosing is very different depending on if gabapentin is being used for seizure control or for pain management. For seizure control gabapentin is typically used three times daily, while for pain control it is usually used once a day. Furthermore, anti-seizure doses are three to ten times higher than analgesic doses, which means that in seizure control expense is likely an issue.
Gabapentin's anti-seizure capabilities have met with mixed reviews among veterinary neurologists. For pain control, gabapentin is usually used in conjunction with other pain relievers that may later be tapered away.
Side Effects
Sedation is the chief side effect of concern. Diarrhea has also been reported.
In mice, male mice on gabapentin were found to have an increased incidence of pancreatic cancer. It is unknown if this finding holds for other species. This information has not hindered FDA approval for human use of gabapentin.
Gabapentin can cause a false positive reading on urine dipstick tests for urinary protein.
Interactions with Other Drugs
For chronic pain relief, gabapentin is best started in combination with other pain relievers but after a time often the other pain relievers can be discontinued and gabapentin is effective as a sole agent.
Oral antacids will hinder absorption of gabapentin into the body by up to 20% so it is important to separate administration of these two medications by at least 2 hours.
Concurrent use of the narcotics hydrocodone or morphine with gabapentin can increase the effectiveness of gabapentin. Concurrent use of gabapentin with hydrocodone will decrease the effectiveness of the hydrocodone.
Concerns and Cautions
Gabapentin may be given with or without food.
Doses for cats are small enough that a compounding pharmacy may need to prepare an appropriate product.
Gabapentin is removed from the body through the kidneys. If it is to be used in a patient with kidney insufficiency the dose will need to be modified, or another product should be selected.
Gabapentin is not safe for use in pregnancy but should be safe for use in lactation.
Gabapentin should not be abruptly discontinued after long-term use as seizures can be precipitated. Instead, gabapentin should be gradually tapered off over a couple of weeks.
Gabapentin oral suspension is sweetened with xylitol which has toxic properties in the dog. The doses used to control pain should not contain enough xylitol to be problematic but anti-seizure doses might. The issue can be avoided by having liquid formulations compounded rather than using the commercially available oral
