About dexamethasone (the active ingredient)

Corticosteroid (glucocorticoid, long-acting).

How it works

Glucocorticoids bind receptors in the cell cytoplasm and the hormone–receptor complex changes which proteins the cell makes; one of these, lipocortin, inhibits phospholipase A2, the first step of prostaglandin and leukotriene production [2].

Key safety points

  • Given in late pregnancy it may cause early parturition or abortion; in cattle glucocorticoids can induce parturition after 255 days of gestation [2][3].
  • In horses, high doses of glucocorticoids may induce or worsen laminitis [2].
  • Long-term use may cause iatrogenic Cushing’s syndrome, and stopping suddenly may lead to an Addisonian-like crisis [2].
  • Except in emergencies, do not use in animals with diabetes mellitus, chronic nephritis, kidney disease, congestive heart failure or osteoporosis [3].
