Good to know there have been to adverse effects from the dosage! I hope the next test shows better results and that you soon start to see some improvements. If the post ACTH # is still a bit high and his signs aren't improved by the next test then a small, SMALL, increase is in order.

As for the cost...it is steep but once he is settled on a dose you can talk to his vet about Trilostane. This is the active ingredient in Vetoryl and it can be compounded into other doses that Vetroryl doesn't come in OR into different forms like a chewable tablet or liquid. The liquid can save you money on top of the saving using the compounded Trilostane because you can easily increase or decrease the dose without a new 'script. So something to think about and discuss with his vet for sure. Not all vets will allow their clients to use the compounded but as long as the pharmacy uses the Trilostane and not a bulk product it usually works just as well while saving you money.

Thanks for the update!
