About prednisolone (the active ingredient)

Corticosteroid (glucocorticoid, intermediate-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

  • Contraindicated with uncontrolled infections, diabetes mellitus, hyperadrenocorticism, heart failure, severe kidney insufficiency, corneal or gastro-intestinal ulceration, and in pregnancy [3].
  • Do not use with live vaccines [3].
  • Give in the morning to dogs and in the evening to cats, to match their natural cortisol peak [3].
  • Long-term use may cause iatrogenic Cushing’s syndrome; stopping suddenly may lead to an Addisonian-like crisis; alternate-day dosing reduces adrenal suppression [2].
  • Glucocorticoids may trigger or worsen diabetes mellitus [2].
