Zycortal is a veterinary injectable suspension for dogs with primary hypoadrenocorticism, commonly called Addison’s disease. Zycortal can be bought online, with the current price shown during ordering and vial quantity selected to match your veterinarian’s written directions. Its active ingredient is desoxycorticosterone pivalate, a long-acting mineralocorticoid replacement used to support sodium, potassium, and fluid balance.
Zycortal Suspension is not an oral tablet or a daily liquid medicine. It is supplied as an injectable suspension, so the product name, concentration, vial volume, and number of vials should be matched carefully to the clinic’s treatment plan. If you are arranging US delivery from Canada, enter accurate owner, pet, clinic, destination, and handling information before completing the order.
Zycortal Price, Strength, and Vial Quantity
The Zycortal price shown at checkout should be read together with the concentration, vial volume, and number of vials. For this medication, one vial does not automatically equal one injection or one month of treatment. Dogs with Addison’s disease often have individualized injection intervals, so the practical cost comparison is the full order: brand, active ingredient, concentration, vial count, and order-specific charges shown before payment.
Zycortal 25 mg/mL describes the concentration of desoxycorticosterone pivalate in each milliliter when that strength is shown. Zycortal 4 mL vial describes the amount of liquid in the vial, not the amount a dog should receive at one visit. A clinic record may use the brand name, the active ingredient name, or both, so each line should match the current treatment instructions.
| Product attribute | What to match | Why it matters |
|---|---|---|
| Brand | Zycortal Suspension | Confirms the medicine being ordered. |
| Active ingredient | Desoxycorticosterone pivalate | Connects brand and ingredient wording on clinic records. |
| Form | Injectable suspension | Distinguishes it from oral medicines and other liquids. |
| Concentration | 25 mg/mL when shown | States strength per milliliter, not the full dose. |
| Vial volume | 4 mL when shown | States total liquid volume in the vial. |
| Quantity | Number of vials | Affects refill planning and the order total. |
Why it matters: A 4 mL vial at 25 mg/mL describes total contents, not an individual dog’s dose.
How to Order Zycortal Online
To order Zycortal online, choose the vial strength and quantity that align with the veterinarian’s directions, then provide complete owner, pet, clinic, and destination details. Treat checkout as a product-matching step, not a dosing decision. If the strength, vial count, or written directions differ from the most recent clinic plan, contact the veterinarian before ordering more medication.
Keep the treatment plan nearby while completing the order. Useful details include the dog’s name, current weight, last injection date, expected injection interval, electrolyte monitoring schedule, and any separate glucocorticoid medicine. These details are especially important when the clinic has recently changed the plan after bloodwork, illness, surgery, or a change in symptoms.
Some owners compare a Zycortal cash pay price when insurance coverage is limited or reimbursement is uncertain. Do not compare only the product name or a single displayed amount. Compare the vial quantity, concentration, handling needs, and service area shown before checkout. Prompt, express, cold-chain shipping may be used when appropriate, but receipt and storage still matter once the package arrives.
What Zycortal Is Used For in Dogs
Zycortal is used as replacement therapy for mineralocorticoid deficiency in dogs with primary hypoadrenocorticism. Primary hypoadrenocorticism, also known as Addison’s disease, occurs when the adrenal glands do not make enough hormones needed for electrolyte and fluid balance. Mineralocorticoids help regulate sodium, potassium, water balance, and blood volume.
The medication replaces the mineralocorticoid component of Addison’s disease care. It does not replace every hormone that may be deficient. Many dogs also need glucocorticoid support, such as a separate corticosteroid medicine, depending on the veterinarian’s diagnosis and monitoring plan. That distinction matters because Zycortal should not be treated as a complete treatment bundle for every dog with Addison’s disease.
Addison’s disease in dogs can produce vague signs, including tiredness, vomiting, diarrhea, poor appetite, weight changes, weakness, dehydration, shaking, or collapse. These signs may come and go, which is one reason the condition is sometimes described as difficult to recognize. A diagnosis and treatment plan should come from a veterinarian using an examination, bloodwork, electrolyte results, and endocrine testing when needed.
The Canine Addison’s Disease collection can help you view condition-related veterinary items in one place. Use it for browsing products connected with the condition, not as a substitute for diagnosis, lab interpretation, or ongoing monitoring.
Active Ingredient and How the Suspension Works
Zycortal Suspension contains desoxycorticosterone pivalate. This active ingredient is a long-acting mineralocorticoid analog, meaning it acts like the hormone component that helps control electrolyte and fluid balance. In dogs with primary hypoadrenocorticism, that replacement can help support sodium and potassium regulation when used under veterinary supervision.
The product is given by injection according to the veterinarian’s plan. The official label describes subcutaneous administration, which means the injection is placed under the skin. Owners should not change the injection route, dose, or interval based on vial contents, price, symptoms, or refill timing.
Because Zycortal is a suspension, the liquid contains dispersed particles of medicine. Suspension products require careful preparation and handling according to the carton, package insert, and clinic instructions. Do not assume that shaking, storage, needle entry, or vial reuse directions are the same as another injectable medicine your dog has used.
Dosing and Monitoring Basics
A Zycortal dose for dogs is based on veterinary judgment, not a standard amount taken from an online description. The veterinarian considers weight, electrolyte results, clinical signs, response to earlier injections, and other medicines. If the dose or interval on the clinic’s instructions does not match what you expected, ask the clinic before ordering more vials.
Monitoring usually focuses on sodium and potassium values, hydration, appetite, thirst, urination, energy level, vomiting, diarrhea, and body weight. These checks help the veterinarian decide whether the next injection timing or amount should be adjusted. Owners should not stretch intervals, split doses, or change other Addison’s disease medicines to make a vial last longer.
The schedule may change over time. Some dogs stabilize after repeated checks, while others need closer monitoring during illness, surgery, boarding, major stress, diet changes, or changes in other medication. Keep lab dates and clinic instructions accessible so the ordered vial quantity continues to match the current plan.
Quick tip: Store recent lab results and injection dates with the dog’s medication instructions.
Storage, Handling, and Vial Safety
Injectable veterinary medicines require careful handling because heat, freezing, contamination, and improper vial use can affect product quality. Follow the carton, package insert, and clinic directions for storage. If the label gives a specific temperature range, use that range rather than storing the vial with ordinary pet supplies.
Plan where the package will be received and how quickly it can be moved indoors. Do not use a vial that arrives damaged, has a broken or altered seal, or looks different from the expected suspension appearance. Contact the clinic if the product has been exposed to questionable storage conditions or if you are unsure whether the vial should be used.
After a vial is first used, follow label and veterinary instructions for needle entry, storage, beyond-use timing, and disposal. Keep vials, needles, and syringes away from children and other animals. Used needles and syringes should go into an approved sharps container, even when injections are administered at home under clinic direction.
Side Effects, Warnings, and When to Call the Veterinarian
Zycortal affects electrolyte and fluid balance, so safety monitoring is part of responsible treatment. Tell the veterinarian if your dog has congestive heart disease, edema, severe kidney disease, liver disease, dehydration, high blood pressure concerns, or any condition that affects circulation or fluid status. The official labeling advises caution in dogs with several of these health issues.
Commonly reported adverse reactions may include lethargy, vomiting, diarrhea, decreased appetite, increased thirst, increased urination, trembling, urinary problems, or changes in general energy. These signs are not always caused by the injection, but they should be recorded and discussed with the clinic. Sudden weakness, collapse, severe vomiting, bloody diarrhea, marked dehydration, or inability to keep food or water down needs urgent veterinary attention.
This medicine is labeled for dogs and should not be used in people. Avoid accidental self-injection and keep all injection supplies secure. If accidental exposure occurs, follow the product label and seek appropriate medical help. Use in breeding, pregnant, or lactating dogs should be discussed with the veterinarian because individual risk assessment may be needed.
Interactions, Health Conditions, and Care Plan Checks
Bring the veterinarian a current list of all medicines, supplements, diets, and recent treatments. Corticosteroids, diuretics, heart medicines, kidney medicines, anti-inflammatory drugs, electrolyte supplements, and special diets can affect fluid balance or lab interpretation. Even non-prescription supplements can matter when a dog is being treated for Addison’s disease.
Ask the clinic how illness days should be handled. Vomiting, diarrhea, poor appetite, surgery, boarding, travel, or major stress may change the monitoring plan or glucocorticoid instructions. Zycortal replaces mineralocorticoid activity, while glucocorticoid support is a separate part of care for many dogs.
If your dog is switching from another mineralocorticoid product, do not overlap or substitute injections without a clinic plan. The veterinarian may need the last injection date, exact product name, dose, lab results, and current symptoms before deciding how to proceed. This is especially important when products look similar but have different directions, concentrations, or vial information.
Zycortal vs Percorten and Related Veterinary Choices
Zycortal vs Percorten is a common comparison because both are mineralocorticoid replacement injections used in dogs with Addison’s disease under veterinary care. They are not automatically interchangeable for ordering. The active ingredient, concentration, vial size, administration directions, and monitoring plan should match the veterinarian’s written instructions.
Owners may also ask whether there is a generic for Zycortal for dogs. Generic availability, brand names, and product status can vary by market, and a product with the same active ingredient name may not have the same vial presentation or instructions. For ordering, the practical step is to match the exact brand or active ingredient, concentration, injectable suspension form, and quantity on the clinic’s treatment plan.
If your veterinarian has discussed another medicine, compare the exact treatment instructions before making a change. The Pet Medications category can help you browse prescribed animal-health products and related veterinary medicines, while your veterinarian should decide whether another mineralocorticoid therapy is appropriate for your dog.
