I took Sadie to the vet last Thursday for blood work and because her current dose of Phenobarbital no longer appeared to be controlling her seizures (2 seizures in just over 3 days!). I got the results yesterday. Her blood work looks good (Yay!!! No liver issues yet) and her phenobarbital level was 25 (needs to be between 15 and 40). Since the seizures were coming more and more frequently on her current dose, and there was room to increase before maxing out, Dr H decided to up her dosage of phenobarbital. Let's hope this works!
