Glucocorticoids are safe if used correctly.
The glucocorticoids can be a veterinarian's and pet's best friend when the latter suffers from some form of inflammation or autoimmune disease, is in shock, or is diagnosed with certain types of cancer. They can also be an enemy if abused. The problems or side effects associated with glucocorticoid usage can occur immediately or long after the drugs have been discontinued. When serious problems do occur, it is usually in cases in which steroids were administered over very long periods of time or at excessive doses. Large single doses or short term use at normal levels rarely, if ever, causes a serious problem unless there is some pre-existing condition such as diabetes, pregnancy, or heart disease.
