Product Overview

Vetoryl (Trilostane) Capsules treat Cushing's disease (hyperadrenocorticism) in dogs. Vetoryl Capsules are an adrenosuppressant medication used to treat Cushing's disease in dogs. Vetoryl is available in strengths of 5 mg, 10 mg, 30 mg, 60 mg, and 120 mg.
For dogs diagnosed with Cushing's Disease (hyperadrenocorticism).

Cushing's disease is a condition where the dog's body produces excess amounts of the hormone cortisol. This hormone is often released into the bloodstream by the adrenal gland in times of stress. Dog's with Cushing's disease produce too much cortisol, and if the disease is left untreated, it becomes incapacitating.

Vetoryl Capsules work to treat common clinical symptoms of Cushing's Disease in dogs, such as:

  • Passing large amounts of urine
  • Urinating often and possible incontinence
  • Excessive thirst and drinking
  • Ravenous appetite
  • Decreased activity or lethargy
  • Excessive panting
  • Skull-like appearance of the head
  • Hyperpigmentation of the skin
  • Thin skin
  • Potbelly
  • Recurrent skin disease
  • Hair loss
  • Loss of muscle

Not every dog displays all signs, check with your veterinarian if your dog has any of these signs.

There is no cure for Cushing's disease in dogs, however, Vetoryl capsules can help manage the clinical signs and improve the dog's quality of life. Most dogs see an improvement in a few weeks, especially in appetite, increased drinking, and increased urination, although the response may vary from dog to dog. Resolution of some symptoms may take longer, such as a potbellied appearance. Some may worsen before they improve, such as hair loss. Speak with your veterinarian about your dog's response to this medication.

If Vetoryl 30 mg capsules or another medication for Cushing's disease in dogs are not given as directed or are discontinued, the excess cortisol production can begin again, and these concerning signs of Cushing's disease can return.

Vetoryl works by controlling excess cortisol production, a hormone that is released from the adrenal gland during times of stress.

Vetoryl capsules contain a medication called trilostane. This drug blocks an enzyme that is key to your dog's adrenal gland's production of cortisol. This lowers your dog's cortisol production.

The effects of Vetoryl (trilostane) are usually temporary, so you will need to continue to give this medication to your dog, even if they seem to be completely recovered. Without a regular supply of Vetoryl, your dog's cortisol production will increase, and they may start to have symptoms that indicate Cushing's disease once more.

In rare instances, diarrhea, poor appetite, vomiting, weakness, and lethargy have been observed.
More serious reactions include:
  • Severe depression
  • Hemorrhagic diarrhea
  • Collapse
  • Hypoadrenocorticism crisis
  • Adrenal necrosis/rupture
Trilostane
Contact your closest emergency animal hospital.
Vetoryl (trilostane) is quickly absorbed through the dog's gastrointestinal tract, so in the case of an overdose, it is critical that you call your veterinarian or an emergency service immediately. Your veterinarian will tell you what action to take, depending on how much Vetoryl your dog has been given and how long it's been since the overdose happened. Gather this information and have it ready when you call your veterinarian or emergency service.
  • Use with caution with dogs in kidney or liver disease.
  • Vetoryl shouldn't be given to dogs that are pregnant.
  • Check with your Vet to ensure Vetoryl is safe to take with your dog's other medications.
Vetoryl capsules are sold in 30 count packs and available in 5 mg, 10 mg, 20 mg, 30 mg, 60 mg or 120 mg strengths.
Dechra Pharmaceuticals

Excess cortisol production can resume and the signs of hyperadrenocorticism can return if you stop giving your dog Vetoryl Capsules.

Once a dog begins treatment, most will require Vetoryl capsules for the remainder of their lives. Unless your veterinarian instructs you to do so, do not stop giving your dog Vetoryl at the dosage and frequency your veterinarian recommends.

If your dog develops any signs of illness while taking Vetoryl capsules, such as vomiting, lethargy, diarrhea, and weight loss, stop treatment right away and call your veterinarian immediately.

If you miss your dog's daily dose, speak with your veterinarian. DO NOT give your dog an extra dose the next day.

Vetoryl saved my dogs life.

The blood test and diagnoses of Cushing disease and the prescribed medication of Vetoryl has made my dog’s misery non existent now. She actually seems like she’s 5 years younger now! Her symptoms of Cushings disease is nonexistent now! She has more energy and has that spunkiness back in her life. I feel like if this issue with her wasn’t diagnosed and the Vetoryl prescribed she probably wouldn’t have a happier and longer lifespan!

Vetoryl is a miracle drug. My dog went from hairless with calcinosis cutis, extreme hunger and thirst, to the outmost fluffy joyful happy dog in the world. The prior veterinarian had him at a dosage that was too low to have any positive impact at 7mg x 2 times a day. The new veterinarian increased the dose to 35mg x 3 times day, and my 24lbs dog has been thriving for the past 3 years. My only negative feedback is to the manufacturer Dechra that manufactures all different dosages using the same pill color. This is very dangerous. In my case, I can't visually distinct the pill at 5mg and the other at 30mg, unless I read the extremely tiny font which is impossible to read to many buyers. Any mistake could be fatal. I would recommend that each dosage has its own pill color.

Our 10 year old dachshund was diagnosed with Cushing's disease last year. It was devastating to know that we could possibly lose her. After purchasing all of her medications from the vet & the high expenses our vet suggested possibly trying to obtain the medication from Allivet which is what we did. We have been very pleased with the price, how the auto ship made it easy to keep us from running low on meds & mostly the customer service which has been absolutely wonderful! Our auto ship had already shipped when we had to take her back to the vet to have her levels checked & her levels had dropped. Her medication dosage had to be lowered. Allivet worked with us & made it a very easy transition. Thank you so much Allivet!!

Our Sampson was diagnosed with Cushing four years ago and this medication was prescribed by our Vet - Immediately after beginning treatment and a dosage adjustment by the Vet, we were happy to see he was back to his old self again. He's a 14 year old Black Lab and has had no problems with this medication, both in the 10 and 30mg dose - The auto-ship of this product has been a great time and money saver and we like the fact they let you know it is ready to ship so you have time to adjust when it will be ship if the need arises. Great product and Allivet is a great company to work with .... Thanks!

Best in class client service. Paula and her team are very knowledgeable, compassionate and understanding. They truly go above and beyond to help their clients. They understand how much we love our fur family, and they make you feel that you are their only priority to help you with whatever is at hand. Product pricing is extremely competitive and that helps when you have one of your fur family members on medication that is expensive. This is a great company and I wouldn’t hesitate in recommending Allivet to anyone. Many thanks Allivet for all you do.

Alicia P Verified Purchase

According to my vet Vetoryl is the best medication available to control Cushing's Disease. Is it the cheapest? No. I wish it were more affordable for everyone so more dogs would be more likely to be treated. My dog was diagnosed with pituitary-dependent Cushing's disease at 7 years old and given a life expectancy of 2 years. I did some research and found out that is not always accurate and my dog would actually be able to live out a full life. The life expectancy given of 2 years was due to most dogs being diagnosed late in life (14 years old is average diagnosis age). For her she simply developed Cushing's disease early but there was no reason to believe her life would be cut short. Here we are 5-6 years later on Vetoryl and she is doing very well. Due to yearly testing and the occasional dosage increase the vet says my dog is at "optimal cortisol levels". When she was originally diagnosed she had lost a lot of muscle tone, her belly became flabby from fat displacement, she was losing her hair in chunks, her skin was turning tough & black in certain areas and she was drinking so much water that she would pee in the house several times a day. Within a few days of starting the Vetoryl her water intake was back to normal so she no longer peed in the house. That in itself made the meds worth it! After a few months on Vetoryl her skin and hair improved drastically. As of today (5-6 years later) she is still on the meds and she is doing very well. Her skin is completely pink as it should be, her hair is fully regrown, she has very little belly fat and she never drinks water in excess. Her muscle tone has not been what it once was but considering she is 13 years old that is to be expected. For anyone on the fence about this medication believe me it works. Now if they would just make it more affordable...
