Understanding Levetiracetam for Cats
Levetiracetam is an antiepileptic drug that vets use to help control seizures in cats.
It works in a different way than older meds and offers flexible dosing and administration.
Vets often pick this medication when managing epilepsy or seizure disorders, sometimes alongside other treatments like phenobarbital.
What Is Levetiracetam?
Levetiracetam, sometimes called Keppra, is an anticonvulsant that vets prescribe to treat seizures in cats.
Itâs actually approved for humans, but vets use it for cats and dogs because itâs pretty safe and effective.
This drug helps cats with epilepsy or seizure disorders, even when the seizures are from brain tumors or donât respond well to other meds.
People like levetiracetam because it usually causes fewer side effects than older anticonvulsants like phenobarbital or potassium bromide.
Most healthy cats and those with ongoing seizure issues handle it well.
How Levetiracetam Helps Manage Seizures
Levetiracetam helps control seizures by stabilizing brain activity.
It works as a stand-alone treatment or as an add-on when other drugs like phenobarbital arenât enough.
Vets pick levetiracetam because it acts fast and can lower how often and how badly cats have seizures.
This comes in handy for cats that keep having seizures even with other treatments.
Cats with repeated seizures often do better on levetiracetam, and it can improve their quality of life.
Itâs also a safer pick for a lot of cats because itâs easier on the liver than some older drugs.

Mechanism of Action and Pharmacokinetics
Levetiracetam works by affecting neurotransmitters in the brain, which helps reduce the abnormal electrical activity that leads to seizures.
It attaches to a protein called SV2A that helps control nerve signal release.
Pharmacokinetic studies in cats show they absorb levetiracetam quickly, whether itâs given by mouth or by injection.
The drug reaches blood levels similar to those used in humans.
Since cats process levetiracetam pretty fast, vets usually give it every 8 hours to keep the drug at steady levels.
This regular dosing helps keep seizures under control.
Formulations and Dosage Forms
Levetiracetam comes in a few forms for cats.
Youâll see oral tablets, chewable tablets, and injectable solutions.
Vets often prescribe oral doses around 20 mg/kg every 8 hours for seizure control.
Thereâs an extended-release version, but cats donât get it as often because the standard dosing is easier to adjust.
Injectable levetiracetam works for emergencies or when cats canât take pills.
Itâs a good option for fast seizure management.
The right form depends on the catâs health, what they can tolerate, and whatâs easiest for the owner.
Safe Administration and Monitoring
Giving levetiracetam to cats means you need to pay attention to the dose and keep an eye on how the cat is doing.
That way, you can make sure itâs working and the cat stays safe.
Watching for side effects and knowing when to get veterinary help is important.
Proper Dosing Guidelines for Cats
Vets usually give levetiracetam at 20 mg per kilogram of the catâs weight every 8 hours.
This schedule keeps the drug level steady and helps prevent seizures.

Most cats take tablets or liquid forms.
Even though the tablets are big, cats usually manage them fine.
If a cat has kidney or liver issues, the vet may need to adjust the dose since those organs clear the drug from the body.
Itâs pretty important to stick to the dosing schedule the vet gives you.
If you miss doses, the drug level can drop and seizures might come back.
Regular blood tests can help the vet see if the dose needs changing.
Side Effects and Adverse Reactions
Most cats tolerate levetiracetam well.
Some might get sleepy, less active, or eat less at first.
A few cats might vomit or drool a bit.
Sometimes youâll see sedation, wobbly walking, or more drooling, but these usually show up early and may get better as the cat adjusts.
Serious side effects donât happen often, but theyâre possible, especially if a cat gets too much or has liver or kidney trouble.
If side effects stick around or worsen, call your vet.
Clinical Monitoring and Safety Concerns
Regular checkups help make sure levetiracetam stays safe and does its job.
Blood tests can show if the drug level is right.
Cats with kidney or liver problems need closer watching, since those organs clear the drug.
Sometimes vets need to adjust the dose to avoid problems.
Keep an eye out for changes in your catâs appetite, alertness, or behavior.
It helps to keep a diary of seizures or anything odd to share with your vet.
When to Seek Veterinary Help in Emergencies
Get emergency vet care if your cat shows signs of overdose or serious reactions.
Things like extreme tiredness, nonstop vomiting, severe wobbliness, or sudden seizures need quick attention.
If your cat stops eating or drinking for more than a day or acts really weird, call your vet right away.
Fast action can help prevent bigger problems.
Itâs smart to have emergency contacts handy and know when itâs time to get urgent care.
Early help can make a big difference.
