I Have A Nine-year-old Foster Female That I Rescued Six

I have a nine-year-old foster female that I rescued six years ago. She has been experiencing seizures, and the that nary and put her on phenobarbital at 6:34 .8 mg and K Bro 500 mg two tablets twice a day every 12 hours. She has not had a seizure sense she has been taking the medicine. She is now pacing around the house, getting stuck in corners, staring at walls, and losing her balance. Is there a medicine that can stop the pacing. She's my baby girl, thank you.
