Who is Vetoryl Capsules 30 Ct. for?

For dogs diagnosed with Cushing's Disease (hyperadrenocorticism).

Why use Vetoryl Capsules 30 Ct.?

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
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.

How does Vetoryl Capsules 30 Ct. work?

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.

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.
