During illness, oral dosing of glucocorticoid may be adjusted to mimic the normal response of the adrenal glands to this stress on the body. Significant fever or injury may require triple oral dosing. Once recovery from the stress event is achieved, dosing is then returned to maintenance levels. People with adrenal insufficiency should know how to increase medication during such periods of stress. Immediate medical attention is needed if severe infections, vomiting, or diarrhea occur. These conditions can precipitate an Addisonian crisis.
