Zycortal 25 mg/ml Prolonged release Suspension for Injection for Dogs 4ml

PRESCRIPTION NEEDED (POM-V)

What Zycortal is used for

Zycortal is licensed as replacement therapy for mineralocorticoid deficiency in dogs with primary hypoadrenocorticism (Addison’s disease). It replaces mineralocorticoid hormones only — most dogs also need a separate glucocorticoid (such as prednisolone) prescribed alongside it.

Strength and pack

25mg/ml desoxycortone pivalate, supplied as one 4ml vial.

How it’s given

Given by subcutaneous injection only. The starting dose is 2.2mg/kg, then individually adjusted using follow-up blood sodium/potassium checks at day 10 and day 25. The interval between doses varies by dog — commonly every 20–46 days, sometimes longer — and is set by your vet, not on a fixed schedule.

Safety information

• Not for use in dogs hypersensitive to desoxycortone pivalate
• A dog in an Addisonian crisis (severe dehydration/collapse) needs IV fluid stabilisation before starting Zycortal
• Extra caution is needed in dogs with heart disease, severe kidney or liver disease, or fluid retention
• Common effects include increased thirst and urination, tiredness, reduced appetite, vomiting, diarrhoea or shaking — contact your vet if you notice anything unusual
• Avoid skin or eye contact when handling; this product should not be given by anyone who is pregnant or breastfeeding; seek medical advice immediately if accidentally self-injected
