What You Need to Know About Gabapentin

What is gabapentin? Why was it prescribed to my pet?
Gabapentin is a medication most often prescribed to treat chronic pain from various causes, including cancer, arthritis and conditions affecting the nervous system.

Gabapentin is sometimes also used as an anti-seizure medication, or to alleviate fear and anxiety prior to stressful events (e.g. grooming, vet visits, thunderstorms). 

What forms are available?
Gabapentin is available in tablet and capsule forms, which are given by mouth. This medication may be given with or without food.

Always follow your veterinarian’s instructions when giving medication to your pet.
Capsule forms:
•    Generic (100mg, 300mg)
Tablet forms:
•    Generic (50mg, 100mg)

Gabapentin is available in both capsule and tablet forms.

What side effects are there?
The main side effects of gabapentin are drowsiness, uncoordinated “drunken” walking and (in cats) occasionally vomiting. These are usually mild and are not a cause for concern unless they are severe, worsen or continue over a long period of time.

Contact your veterinarian if you notice:

•    Rash
•    Severe vomiting or diarrhoea

When should this medication be used very carefully?
Your veterinarian may take additional precautions if your pet: 
•    Has kidney or liver disease
•    Is taking other medications that may cause drowsiness 

Precautions may include measures such as closer monitoring or adjustments to medication doses. For advice specific to your pet, please consult your veterinarian.

When should this medication not be used?
Your pet should not receive gabapentin if they: 
•    Are allergic to it, or to similar medications (e.g. pregabalin)

What monitoring is required for pets on gabapentin?
It is important to take your veterinarian’s advice and bring your pet for rechecks as needed.

Depending on your pet’s underlying condition, your veterinarian may wish to monitor:
•    Your pet’s level of pain
•    For any side effects

Storage and Safety
Keep all medications out of reach of children and pets. Gabapentin should be stored at room temperature in a dry place.

Give this medication for as long as your veterinarian specifies and do not discontinue it without first consulting them. If you miss a dose, give it as soon as possible, but if it is near the time of your pet’s next scheduled dose, skip the missed dose and give the scheduled dose. Afterwards, return to your pet’s regular dosing regimen.

Never give a double dose, even if you miss a dose. Contact your veterinarian if you know or suspect that your pet has received an overdose.
