Percorten-V Cost for Dogs: Addison's Injection Price & Zycortal
Essential Pricing Takeaways
- • Canine hypoadrenocorticism (Addison's disease) requires monthly replacement of mineralocorticoids using desoxycorticosterone pivalate (DOCP) injectable suspensions like Percorten-V or Zycortal.
- • A 4mL multi-dose vial of Percorten-V (25mg/mL) costs $204 to $209 on licensed online pharmacies like Chewy and Walmart PetRx, compared to $290 to $340 when purchased at emergency or specialty hospital desks.
- • Learning to administer subcutaneous DOCP injections at home under your veterinarian's direction saves pet parents $35 to $65 per month in clinic technician injection fees.
An acute Addisonian crisis is among the most alarming emergencies in veterinary medicine, characterized by sudden hypovolemic shock, severe lethargy, vomiting, bradycardia, and dangerous hyperkalemia (elevated potassium). Once stabilized with intravenous fluids and corticosteroids, however, dogs with primary hypoadrenocorticism can live normal, active, and full lifespans on monthly mineralocorticoid replacement therapy.
The primary obstacle for most families is the recurring financial cost of DOCP injections (Percorten-V or Zycortal) combined with daily oral prednisone. In this 2026 price guide, we show you how to source Percorten-V online at substantial discounts and cut monthly treatment expenses in half.

The Biology of Addison's Disease: Mineralocorticoids vs. Glucocorticoids
Addison's disease involves immune-mediated destruction of the adrenal cortex, shutting down the production of both mineralocorticoids (primarily aldosterone) and glucocorticoids (cortisol). Without aldosterone, the canine kidneys cannot conserve sodium or excrete potassium, causing life-threatening cardiovascular arrhythmia.
Percorten-V and Zycortal contain desoxycorticosterone pivalate (DOCP), a long-acting synthetic mineralocorticoid that acts directly on the renal distal tubules to restore sodium reabsorption and potassium excretion. To replace missing cortisol, dogs also take micro-doses of oral daily prednisone.
Calculating Your Dog's Dose: Why Low-Dose Protocols Save Thousands
The original FDA package insert recommends a starting dose of 2.2 mg/kg (1.0 mg/lb) of DOCP every 25 days. However, landmark clinical research conducted at veterinary teaching hospitals has proved that most dogs maintain ideal electrolyte balances on significantly lower doses (1.0 to 1.5 mg/kg) given every 28 to 30 days.
For a 40-pound dog, adopting a low-dose protocol (e.g., 25–30mg total DOCP per month) means a single 4mL vial (100mg total DOCP) lasts 3 to 4 full months instead of just 1.5 months. This veterinary-guided titration cuts annual medication expenses from $1,600 down to under $650.
Step-by-Step: Administering Subcutaneous Injections at Home
Taking your dog to the veterinary clinic every 28 days for a technician injection adds $420 to $780 in annual office fees. While Percorten-V was originally labeled for intramuscular injection, extensive clinical veterinary practice supports subcutaneous administration (under the loose skin behind the neck), which is virtually painless.
Ask your veterinary technician to demonstrate proper needle handling (using sterile 1mL tuberculin syringes with 22-gauge or 25-gauge needles) and vial disinfection. Once confident, ordering your DOCP vials from Chewy or Walmart PetRx and administering at home is simple, stress-free, and immensely economical (see our online pet pharmacy reviews).
