Close encounters with corticosteroids

Close encounters with corticosteroids


Corticosteroids — like prednisone or dexamethasone — can work wonders in dogs with inflammatory disease or an overactive immune system. But they can also have pretty potent adverse effects.

The most common side effects of corticosteroids are panting and increased thirst, urination and appetite. But some dogs develop more serious problems, like digestive tract ulceration, diabetes or pancreatitis. Veterinarians often warn pet parents about these effects, but they’re less apt to mention the possible behavioral properties of corticosteroids.

It’s not uncommon for dogs treated with these drugs to become restless and fearful. They might bark more and play less, become easily startled and avoid people. Some dogs even get aggressive.

So, ask your veterinarian what to expect with corticosteroids — and report side effects that have you concerned.
