Hi! My rabbit Nibbles has seizures also. Hers tend to be partial seizures that last under a minute and it takes her about three minutes to recover. She is being successfully treated with phenobarbital and rarely has seizures any more. Before taking the med, she was having a couple a week and a horrible day she she had cluster seizures with one every couple of hours.
Before starting phenobarbital we took her for a consult with a veterinary neurologist who agreed with our vet with using phenobarbital over other med’s. They felt it was best since it is what is typically used to treat cats and dogs with seizures. It will cause weight gain and the dosage will need to be adjusted accordingly. Nibbles also goes in every couple months to have her liver enzyme levels checked.
The vet doesn’t know what underlying cause of her seizures is but suspects it is damage from an EC infection, so, as suggested by others, treatment for that would be good.
I can let you know the dosage Nibbles gets if that would be helpful.
Sorry you are going through this, it is scary when they are having a seizure. Sending vibes your way!
