We stopped meds
A couple of weeks ago I posted about my dog starting on phenobarbital, he wasn't doing very well at all. I totally expected the wobbliness and ataxia, but it was pretty severe for him. Everyone told me it would pass after a couple of weeks, and I was willing to wait it out. If it was just the ataxia, I would have been fine with it.
Gus doesn't do anything normally. He's had a few uncommon health issues in the past. I'm a vet tech and I've seen many dogs started on a phenobarbital, but I've never seen any get as sick as Gus was.
True to his nature, unfortunately, Gus developed the very rare side effect of phenobarbital: pancreatitis. He had liquid diarrhea, wouldn't eat anything and was vomiting. I woke up one morning to ten piles of liquid diarrhea throughout my house. Gus wasn't the dog I knew, he was miserable and so was I.
Gus has suspected microvascular dysplasia. This is abnormal vasculature in the liver, which makes it harder for the liver to clear medications from the body. With his reaction to the phenobarbital, I'm more confident that he actually does have MVD. It took about three days for him to come back around after stopping the phenobarbital. I had to carry him up and down the stairs, lift him up onto furniture, he wouldn't touch food and just slept all day. He was dragging his hind legs even two days after his last dose. I feel like every time we gave him a dose, we were piling up onto the last dose that hadn't left his system yet.
I spoke with all of the vets I work with as well as Gus's neurologist. We decided what was best would be to try to take Gus off of the phenobarbital. Gus has only had one episode of seizures. The episode involved 2 seizures about 5 minutes apart on June 16.
We decided that we will monitor Gus for further seizures and if they become frequent, we will revisit medications in the future.
Gus has now been off of the phenobarbital since June 26th, and he's back to his normal bratty self. We haven't seen any signs of further seizures so far. We do have emergency intranasal midazolam in case we need it. If seizures do happen in the future, I'll talk to the neurologist again about medication options.
He did have an MRI and we know he doesn't have a tumor or any other brain abnormalities, so that makes me more comfortable with this plan. (On brand for Gus, he's a rare case of idiopathic epilepsy presenting in a senior dog)
Just putting it out there that sometimes medications aren't right for every pet. You have to weigh whats right for your specific situation and you and your dog's quality of life.
