What are the side effects of corticosteroids?
Corticosteroids have many side effects that can be mild or serious. These side effects are more apparent when corticosteroids are used at higher doses or for extended periods of time. This section lists only some of these side effects of corticosteroids.
The prolonged use of corticosteroids can cause obesity, growth retardation in children, and even lead to convulsions and psychiatric disturbances. Reported psychiatric disturbances include depression, euphoria, insomnia, mood swings, and personality changes. Psychotic behaviors also have been reported.
Corticosteroids, since they suppress the immune system, can lead to an increase in the rate of infections and reduce the effectiveness of vaccines and antibiotics.
The long term use of corticosteroids may cause osteoporosis which can result in bone fractures.
Shrinking (atrophy) of the adrenal glands can be caused by the long term use of corticosteroids resulting in the body's inability to produce cortisol, the body's natural corticosteroid, when the systemic corticosteroids are discontinued.
Another condition which can result from the long term use of corticosteroids is adrenal necrosis of the hip joints, a very painful and serious condition that may require surgery. Any symptoms of hip or knee pain in people taking corticosteroids require prompt medical attention.
Corticosteroids should not be stopped suddenly after prolonged use as this can result in adrenal crisis because of the body's inability to secrete enough cortisol to make up for the withdrawal. Nausea, vomiting, and shock are the reported side effects of adrenal crisis.
