Dexamethasone is a synthetic corticosteroid with approximately 25 times the anti-inflammatory potency of naturally occurring cortisol. Corticosteroids such as dexamethasone are important in normal protein, carbohydrate and fat metabolism, and for their role in controlling inflammation. These drugs have both strong beneficial effects and a definite potential to cause negative side-effects. Dexamethasone commonly is used in both small- and large-animal veterinary medicine. It may be given by injection, inhalation, orally, or topically. Preparations for topical use may include other active ingredients such as antibiotics, antifungals, or miticides.
