Zycortal is a veterinary medicine used to treat dogs with Addison’s disease. Addison’s disease is a condition, known as hypoadrenocorticism, where the adrenal glands (located above the kidneys) do not produce enough of two steroid hormones, called cortisol and aldosterone. The lack of aldosterone can cause fluid loss, dehydration and weight loss.
this product is used long-term to replace the missing aldosterone. A corticosteroid medicine is likely to be needed in addition, to replace the cortisol.
