KOR-tih-zone noun

What it means

A natural steroid made by the adrenal glands and an early steroid drug. As a medicine it has mostly been replaced by others such as hydrocortisone and prednisone. People often say "cortisone shot" for any steroid injected into a joint, even though a different steroid is usually used. Long-term steroid use causes high blood glucose, weight gain, thin bones and a higher risk of infection.

For the nurse

Teach clients on long-term steroids not to stop suddenly, because their own adrenal glands may not be making enough hormone; doses are tapered.
