Alternatives to Phenobarbital
Phenobarbital is often the first choice for dogs with seizures. But, there are other seizure medications for dogs besides phenobarbital. These include:
- Levetiracetam – This drug has helped 7 out of 12 dogs with hard-to-treat epilepsy. It cuts down seizures by 81.3% on average. Dogs usually take 20 mg/kg three times a day.
- Zonisamide – It has also shown to reduce seizures by 50% in dogs with hard-to-treat epilepsy. Dogs take 5 to 10 mg/kg twice a day.
- Felbamate – This drug is safe for dogs. Dogs start with 15-20 mg/kg every 8 hours.
- Gabapentin – For dog seizure drugs used instead of phenobarbital, gabapentin is given. Dogs take 25-60 mg/kg every 6-8 hours. It works best at 4-16 mg/L.
Other options like diazepam and topiramate might also be used. Always talk to your vet to find the best treatment for your dog.
“Refractory cases of epileptic dogs, not responding to standard therapy (phenobarbital, bromide), account for 25–30% of all epileptics.”
