General Description

 

Dexamethasone is many times more potent than other anti-inflammatory and immunosuppressing drugs including hydrocortisone and prednisone. It is often mixed with other drugs to treat difficult ear, eye, and skin infections. It reaches every system in the body and therefore is used to treat many disorders:

 

  • Adrenal insufficiency
  • Rheumatoid arthritis
  • Systemic Lupus
  • Allergies
  • Asthma
  • Dermatologic diseases
  • Hematologic disorders
  • Neoplasia (Tumor growth)
  • Nervous system disease
  • Emergency shock
  • General inflammation
  • Inflammatory bowel disease
  • Nephrotic syndrome

 

Dexamethasone is also used in some diagnostic tests, including the Low-Dose Dexamethasone Suppression test (LDDS). This test involves an initial baseline blood sample, an injection of the Dexamethasone, and two subsequent blood draws 4 and 8 hours later. Dexamethasone will suppress the amount of cortisol in a healthy dog, and the cortisol levels will be less than the level before the injection. In a Cushing’s syndrome dog, the levels will be elevated due to an excessive amount of cortisol being produced.

 

How It Works

 

Dexamethasone is a corticosteroid known as a glucocorticoid. Corticosteroids are meant to resemble a naturally occurring hormone produced in the adrenal cortex, cortisol. Corticosteroids act on the immune system by blocking the production of substances that trigger inflammatory and immune responses.

 

Storage Information

 

Keep in a tightly sealed container at room temperature unless otherwise noted. Keep injection protected from light.

 

Missed Dose?

 

Give the dose as soon as possible. If it is almost time for the next dose, skip the missed dose, and continue with the regular schedule. Do not give your pet two doses at once.
