Cort is a type of synthetic corticosteroid medication that is commonly used to reduce inflammation and suppress the immune system. It is often prescribed to treat conditions such as asthma, arthritis, and skin disorders. Cort works by mimicking the effects of cortisol, a hormone produced by the adrenal glands. It can help to alleviate symptoms such as pain, swelling, and redness. However, long-term use of corticosteroids can have side effects, so it is important to use them as directed by a healthcare provider.
