A psoriatic arthritis patient may need to be treated with steroid injections when other treatment methods are not effective at managing their disorder. Corticosteroids are synthetic versions of cortisol, a hormone produced by the adrenal glands. These types of steroids decrease the action of the inflammatory processes and calm down the patient's overactive immune system. Because steroids can produce such effects, they are utilized in the treatment of a wide range of conditions related to inflammation and the action of the immune system.
Steroids can be administered orally to treat inflammation that affects multiple parts of the body simultaneously, or it can be injected into a local inflamed area. Because psoriatic arthritis is not known to produce issues in numerous organs and body systems, systemic steroids are not usually needed or used for treatment. Steroids injected directly into the affected joint(s) are preferred over systemic steroids due to fewer adverse side effects.
