Keppra (Levetiracetam) for Dogs & Cats

If your pet has recently been diagnosed with seizures or another neurologic condition, your veterinarian may have prescribed Keppra (levetiracetam). This medication is widely used to help manage seizures in both dogs and cats, often as part of a long-term treatment plan.

Here’s what pet parents should know about how Keppra works, what to expect, and when to reach out with questions.

What Is Keppra?

Keppra is the brand name for levetiracetam, an anticonvulsant medication used to treat seizures in pets. It’s generally considered safe for both dogs and cats and may be used alone or alongside other medications like phenobarbital or zonisamide for pets with more complex seizure conditions.

At Remedy, we often choose Keppra because it's well tolerated and doesn’t require blood monitoring in most cases.

What’s the Difference Between Keppra and Keppra XR?

Keppra (regular): Given every 8 hours

Keppra XR (extended release): Given every 12 hours
(Only appropriate for pets that can swallow pills whole & not to be split or crushed)

We’ll help you choose the version that works best for your pet and your schedule.

Dosing and Timing

Keppra is most effective when given on a strict schedule. Missing a dose or giving it late can increase the risk of a seizure.

If your pet misses a dose, vomits shortly after taking it, or refuses to take it, call us. We’ll let you know whether to repeat the dose or wait for the next one.

Possible Side Effects

Most pets tolerate Keppra well, but mild side effects may include:

Sleepiness
Wobbliness or unsteadiness
Mild nausea or GI upset

Call us if you notice:

Extreme lethargy
Behavior changes
Difficulty walking
Vomiting with every dose

What to Expect Over Time

Keppra can take a few weeks to fully stabilize your pet’s condition. It may be used long-term, adjusted over time, or combined with other medications depending on how your pet responds.

Every treatment plan is customized and we’ll be right here to monitor progress, answer questions, and adjust as needed.
