Dr. Susan :

Hi, I can help you with your question today.

Dr. Susan :

I'm not sure what medication Simba has been on so far - Accutane is not used in veterinary medicine to treat Cushings disease.

Dr. Susan :

Perhaps you mean trilostane?

Dr. Susan :

If so, 2 mg/kg is a low dose. We can slowly increase the dose as needed to get control of his signs and improve his cortisol measurements on the ACTH Stim test.

Dr. Susan :

Another option is a drug called Lysodren.

Dr. Susan :

As far as retinoic acid goes, this has been used with some success for Cushing's disease as well.

Dr. Susan :

The dose for this medication is 2 mg/kg/day as well.

Dr. Susan :

We use the 9-cis isomer of retinoic acid to treat. I have not looked into this option recently, but in the past (several years ago) it was very expensive. It was probably several hundred dollars per week.

Dr. Susan :

Most of my clients choose the Lysodren or trilostane route.
