Topiramate (Topamax®)

Topiramate (Topamax®) Seizure Medication for Dogs & Cats

Topiramate (Topamax®) is an anticonvulsant medication used to help manage seizures in pets by reducing seizure frequency and severity. While it can significantly improve seizure control, it may not completely eliminate all seizures.

Topiramate Dosing & Administration

Topiramate is typically administered twice daily and can be given with or without food. Consistency matters for seizure control, so set reminders to help keep dosing on schedule. Keep track of your medication supply and arrange refills at least one week in advance to avoid interruptions.

Missed Doses & Changing Medications

If your pet misses a dose of topiramate, give it as soon as you remember unless it’s close to the next scheduled dose time on the prescription label. If it’s close, skip the missed dose and give the next dose at the regular scheduled time. Do not administer double doses.

Do not stop or change the dose without veterinary guidance. Seizure medications generally need tapering rather than abrupt discontinuation.

Monitoring & Lab work

Regular veterinary check-ups are important for pets taking seizure medications. Biannual visits are recommended to discuss your pet’s response to treatment.

Because topiramate isn’t commonly used in veterinary medicine and long-term effects may be unknown, comprehensive blood work (CBC and chemistry) and urinalysis are recommended every six months.
