Vetoryl For Cushing's: Can It Cause Addison's In Dogs?

Cushing's disease, or hyperadrenocorticism, is a condition that primarily affects older dogs. It is caused by the overproduction of cortisol, a hormone that helps the body deal with stress. While there is no cure for Cushing's disease, medications such as Vetoryl can help manage the symptoms and control the cortisol levels in a dog's body. However, it is important to note that Vetoryl is not without its side effects, and one of the known side effects of Vetoryl is the development of Addison's disease, or hypoadrenocorticism. This occurs when the cortisol levels drop too low due to an excessive dosage of Vetoryl. Therefore, to answer the question, yes, a dog on Vetoryl for Cushing's disease can become Addison's.

Vetoryl side effects: lethargy, vomiting, diarrhoea, and loss of appetite

Vetoryl is a prescription drug for dogs that treats Cushing's disease, or hyperadrenocorticism, by reducing the production of cortisol. While it is not a cure, it can control the clinical signs of the disease.

As with all drugs, side effects may occur. The most common side effects of Vetoryl are:

• Lethargy: Dogs on Vetoryl may show signs of tiredness, which can be a mild and temporary side effect. However, it is crucial to monitor your dog to ensure it does not develop into prolonged lethargy, as this can be a sign of Addison's disease.
• Vomiting: Prolonged, frequent, or severe vomiting should be reported to your vet immediately, as this can be a sign of Addison's disease.
• Diarrhoea: Prolonged, frequent, or severe diarrhoea should also be reported to your vet immediately, as it may indicate Addison's disease.
• Loss of appetite: Vetoryl reduces excess cortisol levels, which should normalise your dog's appetite and water consumption. However, if your dog has below-normal appetite and water intake, contact your vet immediately, as this can be a sign of Addison's disease.

If you notice any of these side effects, it is important to stop Vetoryl treatment and contact your veterinarian immediately.

Cushing's disease symptoms: excessive drinking, urination, skin problems, and hair loss

Cushing's disease, or hyperadrenocorticism, is a condition where the adrenal gland produces excess cortisol, a type of hormone. This can be caused by a tumour on the pituitary or adrenal glands, or by taking steroid medications for a long time. Cushing's disease typically occurs in middle-aged to older dogs and can cause a range of symptoms, including:

• Excessive drinking and urination
• Skin problems
• Hair loss

Dogs with Cushing's disease may also experience increased appetite, lethargy, abdominal enlargement, and recurrent skin infections. While the disease typically develops slowly, these symptoms can have a significant impact on a dog's quality of life. Left untreated, Cushing's disease can lead to potentially life-threatening conditions such as diabetes, blood clots, infections of the kidneys and urinary tract, and pancreatitis.

Vetoryl (trilostane) is a prescription drug used to treat Cushing's disease in dogs. It works by stopping the production of cortisol in the adrenal glands, helping to control the signs and symptoms of the disease. While Vetoryl can be effective in managing Cushing's disease, it is important to monitor dogs closely for any side effects, as excessive Vetoryl can lead to Addison's disease, a condition where cortisol production stops altogether.

Vetoryl is a man-made steroid that lowers cortisol production

Vetoryl is a prescription medication used to treat Cushing's disease in dogs. It is a man-made steroid that lowers cortisol production by binding to the cortisol-producing enzymes in the adrenal glands. This prevents these enzymes from binding to the molecules they need to produce cortisol, thus reducing the amount of cortisol in the body.

Cushing's disease, or hyperadrenocorticism, is a condition where the body produces too much of the hormone cortisol. Cortisol is normally produced and stored by the adrenals, two small glands that sit on top of the kidneys. While normal levels of cortisol help the body respond to stress and fight infections, too much cortisol can weaken the immune system and lead to other health issues.

Vetoryl is the only drug approved by the FDA to treat both pituitary-dependent and adrenal-dependent Cushing's disease in dogs. It helps control the signs and symptoms of Cushing's disease, including excessive drinking and urination, skin problems, increased appetite, and lethargy. It is important to note that Vetoryl manages the symptoms of Cushing's disease but does not cure it.

As with all medications, side effects may occur with Vetoryl. Some common side effects include vomiting, diarrhoea, lethargy, reduced appetite, and weakness. In rare cases, more serious side effects such as severe depression, haemorrhagic diarrhoea, collapse, or adrenal necrosis/rupture may occur. It is important for pet owners to closely monitor their dogs and report any side effects to their veterinarian.

Vetoryl should not be given to dogs with kidney or liver disease, or to pregnant dogs. It should also be used with caution in dogs taking certain medications, such as those used to treat heart disease.

Cushing's disease causes: an increase in cortisol due to a breakdown in communication between glands

Cushing's disease, or hyperadrenocorticism, is a condition where the body produces too much of the hormone cortisol. Cortisol is produced and stored by the adrenals, two small glands that sit on top of the kidneys. It is a natural steroid, and in normal amounts, it helps the body adapt in times of stress, fight infections, and maintain a healthy weight. However, when the body produces excess cortisol, it can lead to Cushing's disease.

In dogs, Cushing's disease occurs naturally and is either pituitary-dependent or adrenal-dependent. Pituitary-dependent Cushing's disease is triggered by a tumour on the pituitary gland, a pea-sized gland at the base of the brain. This type accounts for about 80-85% of cases. The pituitary gland produces adrenocorticotropic hormone (ACTH), and when a tumour is present, it causes an overproduction of ACTH. This travels through the bloodstream to the adrenal glands, stimulating them to produce more cortisol than the body needs.

On the other hand, adrenal-dependent Cushing's disease occurs when there is a tumour on one or both adrenal glands, leading to the direct overproduction of cortisol. This type accounts for approximately 15-20% of cases.

Vetoryl (trilostane) is a medication used to treat both types of Cushing's disease in dogs. It works by stopping the production of cortisol in the adrenal glands. While it manages the signs of the disease, it does not cure it. The only way to cure Cushing's disease is to remove the adrenal tumour if it is present and has not spread. However, due to the complexity and risks of the surgery, most cases are managed with medications like Vetoryl.

It is important to monitor dogs taking Vetoryl closely, as one of its side effects is abnormally low cortisol levels, also known as Addison's disease. This can occur when the dosage of Vetoryl is too high, causing a halt in cortisol production. Addison's disease can present as a collection of vague clinical signs, such as diarrhoea, vomiting, trembling, and weakness, and can lead to an "Addisonian crisis", requiring immediate veterinary attention.

Cushing's disease treatment: medication or surgery to remove the adrenal tumour

Cushing's disease, or hyperadrenocorticism, is caused by the body producing too much of the hormone cortisol. Cortisol is produced and stored by the adrenals, two small glands that sit on top of the kidneys. Cushing's disease can be either pituitary-dependent or adrenal-dependent. In 80% to 85% of cases, it is triggered by a tumour on the pituitary gland, which stimulates the adrenal glands to produce more cortisol. In the remaining 15% to 20% of cases, a tumour in one or both adrenal glands produces excess cortisol.

Veterinarians typically treat Cushing's disease with medication. The only way to "cure" the disease is to remove the adrenal tumour surgically if it is adrenal-dependent and the tumour hasn't spread. However, due to the complexity and risks of the surgery, most cases are treated with medication.

Vetoryl (trilostane) is the only drug approved by the FDA to treat both pituitary- and adrenal-dependent Cushing's disease in dogs. This prescription drug works by stopping the production of cortisol in the adrenal glands. It is typically needed for the rest of the dog's life once they have been diagnosed with Cushing's disease. It should be given with food, usually in the morning, and always according to the vet's instructions. Frequent blood tests and veterinary checkups are required in the first few months after starting treatment and then every few months thereafter, depending on the dog's response.

While Vetoryl can be effective in managing the signs of Cushing's disease, it does not cure it. It also has potential side effects, which affect about 40% of dogs and can be serious. These include vomiting, diarrhoea, lethargy, weakness, reduced appetite, unmasked arthritis, incoordination, wobbliness, bloating, muscle tremors, and in rare cases, sudden death. One important side effect is abnormally low cortisol, or Addison's disease, which can be life-threatening and requires immediate veterinary attention.
