There is however a very large risk of a traumatic seizure event if you try to discontinue
Keppra. There is no evidence that
Keppra poses any long term health risk, humans have been using it
for almost 2 decades. If your 4 legged best friend is on Phenobarbital and/or K.bromide you should discuss with your vet about the risk/benefits of weaning off those and/or transitioning to Keppra as those 2 drugs can cause liver/kidney damage in the long term.
