Levetiracetam is an anticonvulsant drug that is used to treat seizures and epilepsy in dogs and cats. It's a medication often used as additional therapy to treat these conditions in dogs when their seizures are not well controlled by phenobarbital or bromides. It can also be used to treat seizures caused by hepatic encephalopathy or liver damage.
Levetiracetam for cats can be used as an add-on medication or can be dosed as a single therapy for cats that are unable to tolerate phenobarbital. In horses, levetiracetam can be used as an anticonvulsant.
Levetiracetam is a prescription medication that your veterinarian will prescribe to your pet based on their individual condition.
The medication is given every 8 hours and should take effect within 1 to 2 hours. Since the full effects may not be obvious right away, your veterinarian may monitor your pet with different tests to evaluate the efficiency of the medication.
