Product Description

Percorten-V 25 mg/mL, 4 mL Vial is the only FDA-approved medication for treating dogs with primary adrenocortical insufficiency, or Addison’s Disease in dogs.

The main ingredient Desoxycorticosterone Pivalate (DOCP) in Percorten-V dog medication by Novartis is a mineralocorticoid hormone and an analog of desoxycorticosterone.

DOCP replaces the depleted mineralocorticoid steroids and prevents the buildup of toxic substances in the bloodstream. This pet medication extends your dog’s quality of life if he is suffering from primary adrenocortical insufficiency or Addison’s Disease in dogs.

Now you can order FDA-approved medication and other pet prescription medication online and get the pets prescribed drugs delivered right at your doorstep. At our online pet meds pharmacy based in Texas, you can order high quality dog medications.

Federal (U.S.A.) law restricts this dog medication to use by or on the order of a licensed veterinarian.


Desoxycorticosterone pivalate (DOCP), like other adrenocorticoid hormones, is thought to act by controlling the rate of synthesis of proteins. It reacts with receptor proteins in the cytoplasm to form a steroid-receptor complex. This complex moves into the nucleus, where it binds to chromatins that result in genetic transcription of cellular DNA to messenger RNA. The steroid hormones appear to induce transcription and synthesis of specific proteins which produce the physiologic effects seen after administration.

Desoxycorticosterone pivalate (DOCP) is a long-acting ester of desoxycorticosterone acetate (DOCA) which is recognized as having the same qualitative effects as the natural mineralocorticoid hormone aldosterone.

The most important effect of DOCP is to increase the rate of renal tubular absorption of sodium. This effect is seen most intensely in the thick portion of the ascending limb of the loop of Henle. It also increases sodium absorption in the proximal convoluted tubule but this effect is less important in sodium retention. Chloride follows the sodium out of the renal tubule and aids in symptoms like low blood sodium level.

Another important effect of DOCP is enhanced renal excretion of potassium. This effect is driven by the resorption of sodium which pulls potassium from the extracellular fluid into the renal tubules, thus promoting potassium excretion. This eases high blood potassium level.

DOCP also acts to increase extracellular fluid volume. The enhanced retention of sodium, chloride and bicarbonate, creates an osmotic gradient that promotes water absorption from the renal tubules. The extracellular fluid volume is supported. This expands the blood volume and improves the venous return to the heart and cardiac output. The expanded blood volume and increased cardiac output may result in elevated blood pressure.

This dog medication prevents the life threatening hypotensive shock and pre-renal azotemia observed in animals suffering from hypoadrenocorticism.

The effects of FDA -approved medication on electrolytes and extracellular fluid volume are dependent on a functioning kidney. Animals suffering from hypovolemia, pre-renal azotemia, and inadequate tissue perfusion must be rehydrated with intravenous fluid (saline) therapy, before starting PERCORTEN-V therapy. Primary renal disease should be ruled out before starting PERCORTEN-V therapy.

DOCP is an insoluble ester of desoxycorticosterone.

The crystals are injected intramuscularly as a micro-crystalline depot where they slowly dissolve over time.


This pet injection is for use as replacement therapy for the mineralocorticoid deficiency in dogs with primary adrenocortical insufficiency.


Do not use this pet meds in pregnant dogs. Also, do not use this medicine in dogs suffering from congestive heart disease, severe renal disease or edema.

Keep this and all drugs out of the reach of children. In case of human consumption, contact a physician or Poison Control Center immediately.


Some patients are more sensitive to the actions of PERCORTEN-V and may exhibit side effects in an exaggerated degree. Some patients may show signs of hypernatremia or hypokalemia. The dosage of this dog medication should be reduced in these patients.

Like other adrenocortical hormones, PERCORTEN-V may cause severe side effects if dosage is too high or prolonged. It may cause polyuria, polydipsia, increased blood volume, edema and cardiac enlargement.

Excessive weight gain may indicate fluid retention secondary to sodium retention.

This FDA-approved medication to treat Addison’s disease in dogs should be used with caution in patients with congestive heart disease, edema or renal disease.


The following adverse reactions have been reported following the use of PERCORTEN-V: depression, polyuria, polydipsia, anorexia, skin and coat changes, diarrhea, vomiting, weakness, weight loss, incontinence, pain on injection and injection site abscess. Some of these effects may resolve with adjustments in dose or interval of PERCORTEN-V or concomitant glucocorticoid medication.


PERCORTEN-V given intramuscularly at the appropriate dose and interval is effective in replacing the mineralcorticoid deficiency in dogs suffering from primary hypoadrenocorticism.

Results of two 75-day clinical studies in dogs with primary hypoadrenocorticism have demonstrated the clinical efficacy of PERCORTEN-V. Each dog received three doses of PERCORTEN-V, pet injection (on days 0, 25 and 50).

The results are summarized below.

Case Management:

An accurate diagnosis of primary canine adrenocortical insufficiency is of paramount importance for treatment success and should be established before initiation of PERCORTEN-V therapy. While hyponatremia and hyperkalemia are highly suggestive of adrenocortical insufficiency, they are not pathognomonic. A definitive diagnosis can only be made with an ACTH stimulation test. At diagnosis, classic cases of canine adrenocortical insufficiency may include clinical signs. Those signs are anorexia, lethargy, depression, weakness, vomiting and/or regurgitation, weight loss, diarrhea and collapse, serum sodium values less than 135 mEq/L, serum potassium greater than 6 mEq/L, sodium/potassium ratios below 25:1, plasma or serum cortisol concentration less than 4 μ g/dl pre-and-post ACTH administration.

Once the diagnosis is made, immediate therapy must be given to normalize electrolyte imbalance, correct hypovolemic shock and re-establish normal homeostasis. Such therapy should include large volumes of intravenous physiologic saline, glucocorticoids (i.e., prednisolone, dexamethasone) at shock doses and PERCORTEN-V. Once the acute crisis has passed, renal and cardiovascular function should return to normal. Then begin chronic lifelong therapy with PERCORTEN-V and glucocorticoids.


In a laboratory study the safety of PERCORTEN-V was established in five month old Beagle dogs.

PERCORTEN-V FDA-approved medication was administered IM to 24 Beagles at 0, 2.2, 6.6 or 11 mg/kg of body weight daily over a consecutive 3-day period every 28 days (equivalent to a cumulative monthly dosage of 0, 6.6, 19.8 or 33 mg/kg) for 6 months. This resulted in no mortality or any significant effects on body weight, food consumption, and ophthalmic observations at any dose level. However, polyuria and polydipsia were noted and creatinine concentration decreased (14-89 mg/dl) in the 1X, 3X and 5X groups. Histopathological changes were only observed in the kidneys when PERCORTEN-V was administered at ≥ 6.6 mg/kg. The primary renal lesion consisted of glomerulonephropathy seen in all males at ≥ 6.6 mg/kg, in one female at 6.6 mg/kg, and in all females at 11 mg/kg. Other possible treatment related lesions in the kidney, observed sporadically in the 6.6 and 11.0 mg/kg groups, were tubular hyperplasia, inflammation and tubular dilatation.

Glomerulonephropathy may possibly be attributed to the pharmacological effects of the drug although there were no clinical measurements assessed in this study. In conclusion, PERCORTEN-V was well tolerated, when administered at 2.2 mg/kg on three consecutive days in every 28-day period for six months.


In treating canine hypoadrenocorticism, PERCORTEN-V replaces the mineral corticoid hormones only.

Glucocorticoid replacement must be supplied by small daily doses of glucocorticoid hormones (e.g., prednisone or prednisolone) (0.2 – 0.4 mg/kg/day).

Dosage requirements of this dog medication to treat Addison’s disease in dogs are variable and must be individualized on the basis of the response of the patient to therapy. Begin treatment with PERCORTEN-V at a dose of 1.0 mg per pound of body weight every 25 days.

In some patients, the dose may be reduced. Serum sodium and potassium levels should be monitored to assure the animal is properly compensated. Most patients are well controlled with a dose range of 0.75 to 1.0 mg per pound of body weight, given every 21 to 30 days.

The well-controlled patient will have normal electrolytes at 14 days after administration or may exhibit slight hyponatremia and hyperkalemia. This needs no additional therapy as long as the patient is active and eating normally. Watch closely for depression, lethargy, vomiting or diarrhea which indicates a probable glucocorticoid deficiency.

At the end of the 25-day dosing interval, the patient should be clinically normal and have normal serum electrolytes. Alternatively, they may have slight hyponatremia and slight hyperkalemia. This constellation of signs indicates that the dosage and dosage interval of this pet medication should not be altered.

If the dog is not clinically normal or serum electrolytes are abnormal, then the dosage interval should be decreased 2-3 days.

Occasionally, dogs on PERCORTEN-V therapy may develop polyuria and polydipsia (PU/PD). This usually indicates excess glucocorticoid, but may also indicate a PERCORTEN-V excess. It is prudent to begin by decreasing the glucocorticoid dose first. If the PU/PD persists, then decrease the dose of PERCORTEN-V without changing the interval between doses.

Please note: Failure to administer glucocorticoids is the most common reason for treatment failure.

Signs of glucocorticoid deficiency include depression, lethargy, vomiting and diarrhea. Such signs should be treated with high doses of injectable glucocorticoids (prednisolone or dexamethasone), followed by continued oral therapy (0.2 – 0.4 mg/kg/day). Oral supplementation with salt (NaCl) is not necessary with animals receiving PERCORTEN-V.
