Phenobarbital frequency
I wanted to see if anyone has experience with giving phenobarbital every 8 hours. My dog (now 7 year old cattle dog mix) was diagnosed idiopathic in 2023 but was able to go 2 years without any meds, until last winter when they started to become more frequent. We started with Keppra and then maxed out (2000mg every 8 hours) as he started to have clusters (hours apart), then added phenobarbital (97 mg every 12 hours) and had one increase already (129 mg every 12 hours). His levels have gone from 28 to 18, increased dosage, then levels at 32 have dropped to 27 over about 2 months. He is still having breakthroughs every 20-40 days, which our neuro is not super happy with. We have been given the choice of trying Pheno every 8 hours or just add zonisamide. I have read the one research paper looking at the benefits of giving every 8 hours but wanted to see if anyone has tried this dosing long term successfully or if I am just prolonging the inevitable and should just add zonisamide now.
