Vetoryl 30mg Capsule for Dogs - per Capsule

Description

Vetoryl 30mg Capsules are a prescription-only veterinary medicine for dogs diagnosed with pituitary-dependent or adrenal-dependent hyperadrenocorticism, more commonly called Cushing's syndrome. Each hard capsule contains 30mgof trilostane, an adrenal enzyme inhibitor used to reduce excessive steroid hormone production.

Cushing's syndrome develops when the body is exposed to too much cortisol over a prolonged period. Cortisol is essential in normal amounts, helping to regulate metabolism, blood pressure, immune responses and the response to stress, but persistent excess can affect every body system. Vetoryl 30mg Capsules are not a general treatment for thirst, hair loss or ageing-related changes; a veterinary surgeon must first confirm that these signs are consistent with hyperadrenocorticism and select the appropriate strength. The 30mg capsules allow the prescribed daily amount to be built from available capsule strengths, according to body weight, clinical response and blood-test results. This medicine is for dogs only and requires a valid veterinary prescription.

Vetoryl 30mg Capsules contain trilostane, which selectively and reversibly inhibits the adrenal enzyme 3 beta-hydroxysteroid isomerase. This interrupts a key step in the production of cortisol, corticosterone and aldosterone. Lowering circulating glucocorticoid and mineralocorticoid levels helps bring hormone activity closer to a range the dog's body can manage. Vetoryl 30mg Capsules control hormone overproduction rather than removing the pituitary or adrenal tumour that may be driving it, so ongoing treatment and monitoring are usually required.

Some signs, such as excessive thirst, urination and appetite, may improve before skin, coat and muscle changes. Response times vary, and a dog that appears brighter at home still needs scheduled checks because clinical appearance alone cannot show whether cortisol suppression is safe. Its dose-dependent, reversible action allows careful adjustment, but owners must never raise, reduce or stop the dose without veterinary advice, except while seeking urgent help for a suspected adverse reaction.

Canine Cushing's syndrome is usually caused either by a small ACTH-secreting pituitary tumour, which repeatedly stimulates both adrenal glands, or by a cortisol-producing adrenal tumour. In both forms, chronic cortisol excess changes water balance, fat distribution, muscle strength, skin integrity and resistance to infection. Vetoryl 30mg Capsules are licensed for both pituitary-dependent and adrenal-dependent disease, but they do not replace investigation of the underlying cause. Common signs include polyuria and polydipsia, meaning increased urination and thirst; polyphagia, meaning increased appetite; panting; a pendulous or pot-bellied abdomen; lethargy; muscle wasting; symmetrical hair loss; thin skin; poor hair regrowth; and recurrent skin or urinary infections. Not every dog shows every sign, and several other illnesses can look similar. Vetoryl 30mg Capsules may also reveal previously hidden kidney disease when excess cortisol is reduced, while dogs with concurrent diabetes mellitus need particularly close supervision. A diary of water intake, toileting, appetite, panting, energy, skin changes and body weight gives the veterinary team valuable evidence when reviewing control.

Monitoring is essential with Vetoryl. Before treatment, the vet will usually confirm the diagnosis and assess general health, especially liver and kidney function. The product information recommends biochemistry, including electrolytes, and an ACTH stimulation test before treatment, then around 10 days, four weeks and 12 weeks after starting, every three months thereafter, and after each dose adjustment. For reliable interpretation, the ACTH stimulation test is normally performed four to six hours after Vetoryl 30mg Capsules are given. Your practice may tailor the testing plan to the dog's history, concurrent disease and current clinical guidance. Blood results are considered alongside signs at home; a cortisol result should not be viewed in isolation. The vet may review sodium and potassium, liver enzymes, urea, creatinine, packed-cell volume and glucose where relevant. Keep appointments throughout the treatment period even when the dog seems well, and tell the practice about all prescription medicines, supplements and diet changes, as older dogs commonly have more than one condition that can influence treatment decisions.

What are Vetoryl Capsules used for in dogs?
Vetoryl 30mg Capsules contain trilostane and are prescribed for pituitary-dependent or adrenal-dependent hyperadrenocorticism, commonly called Cushing's syndrome. They reduce excessive adrenal steroid production, helping to control increased thirst, urination, appetite, panting, muscle weakness and skin changes. A veterinary surgeon must confirm the diagnosis and select the appropriate dose.

How does Vetoryl 30mg work?
Trilostane, the active ingredient, selectively and reversibly inhibits an enzyme used by the adrenal cortex to make cortisol and certain other steroid hormones. By reducing excessive hormone production, Vetoryl 30mg can help control the clinical effects of Cushing's syndrome. It manages hormonal activity but does not remove an underlying pituitary or adrenal tumour.

How quickly might my dog improve after starting Vetoryl 30mg Capsules?
Improvement varies between dogs. Excessive thirst, urination and appetite may settle before coat, skin and muscle changes, which can take longer to improve. Keep a daily record of drinking, toileting, appetite, panting and energy. Even when progress is noticeable, scheduled blood tests remain essential to check that cortisol suppression is safe.

What side effects should I watch for with Vetoryl 30mg Capsules?
Possible adverse effects include lethargy, loss of appetite, vomiting and diarrhoea. Weakness, incoordination, tremors or collapse can indicate excessive adrenal suppression and require urgent veterinary attention. Do not give another dose until the veterinary surgeon advises you. Prompt assessment is important because electrolyte disturbance and an acute Addisonian crisis can become serious.

What should I do if I miss a dose of Vetoryl 30mg Capsules?
Do not give two capsules together or double the next dose unless your veterinary surgeon has specifically instructed this. Contact the practice for advice based on the timing and your dog's treatment plan. Once advised, return to the normal schedule. Giving the medicine consistently with food helps maintain predictable absorption and monitoring results.

Can Vetoryl 30mg Capsules be opened or divided?
No. Vetoryl 30mg Capsules should be swallowed whole and must not be opened, divided or crushed. The granules can irritate the skin and eyes, and opening a capsule prevents accurate dosing. Pregnant women and anyone trying to conceive should avoid handling them. Wash your hands after administration or accidental exposure.
