Understanding Medical Treatment for Cushing’s in Dogs
If your vet brings up medical treatment, it helps to know what you’re working with first.
Medical treatment is a proven, widely used way to manage Cushing’s. But like any treatment, it has trade-offs worth understanding.
Surgery
Recommended for rare adrenal-tumor cases. High risk and high cost, so vets reserve it for specific situations.
Medications
The most common path. These lower cortisol, usually by acting on the adrenal gland.
Disclaimer: Cushing's is treatable but not curable. No medication removes the tumor behind the disease. Any treatment is about managing your dog's cortisol and keeping them comfortable.
Surgery
Cushing’s usually comes from a tumor on either the pituitary gland or the adrenal gland, and which one decides whether surgery is even possible.
About 80% of cases come from a pituitary tumor, and surgery isn’t recommended there. Brain surgery on dogs is risky and very expensive, so vets avoid it.
The rarer adrenal-tumor cases can sometimes be operated on, and in the right situation surgery may even resolve the disease, though vets weigh the risk carefully before choosing it.
For most dogs, that leaves medication or natural remedies, often used together as part of a plan with your vet.
Medications
Most Cushing’s medications lower the cortisol that’s driving your dog’s symptoms. But, they differ in how they get there. Many work by acting on the outer layer of the adrenal gland to slow cortisol production, which is what makes them effective, especially in more serious cases.
Because they work directly on the gland, these medications can come with side effects. Common ones include:
- Vomiting
- Diarrhea
- Loss of appetite
- Low energy
- Cortisol drop
Your vet monitors for these and adjusts the dose to keep things on track.
There’s also one risk worth knowing: too much adrenal change can lead to Addison’s disease, where cortisol production drops too low. Regular bloodwork is how your vet stays ahead of it.
VET’S NOTE: If your dog is on stronger medication, your vet may give you Prednisone tablets for emergencies. Follow the dosing exactly.
MEDICATION REFERENCE
All You Need To Know About Common Cushing's Medications
If your vet suggests medication, here’s a quick breakdown of the options they might mention and the trade-offs that come with each.
Lysodren (Mitotane)
The longest-used option and, to many vets, the most effective for severe cases. Works in a 4–6 month window.
Lower cost than the others and easy to give as a chewable. Needs monitoring, as it acts directly on adrenal tissue.
Trilostane
A newer option, often used for dogs that don't tolerate Lysodren.
Easier on adrenal tissue, though pricier and given more often. Needs a one-month gap when switching from Lysodren.
Ketoconazole
An antifungal that also blocks adrenal hormone production. Helps about half of dogs.
Anipryl
The mildest option, with side effects in under 5% of dogs. Milder also tends to mean a gentler effect on symptoms.
