Zycortal is indicated for the treatment of primary hypoadrenocorticism in dogs, a condition where the adrenal glands do not produce adequate amounts of corticosteroids, particularly aldosterone. It replaces the mineralocorticoid hormone to help maintain proper electrolyte balance, fluid levels, and blood pressure.

As a mineralocorticoid, Zycortal helps the kidneys retain sodium and excrete potassium, which is essential for maintaining normal electrolyte balance and blood pressure. The pivalate formulation provides a long-acting depot effect, typically requiring administration every 25-30 days.

Zycortal is administered by subcutaneous injection by a veterinarian. Dogs typically require concurrent oral glucocorticoid supplementation (such as prednisone). Overdose or incorrect dosing may lead to polydipsia, polyuria, edema, or hypertension. Regular monitoring of electrolytes and clinical response is necessary to adjust dosing appropriately. This medication is for veterinary use only in dogs.
