Joseph Bennington-Castro is a Hawaii-based contributing writer for Live Science and . He holds a master's degree in science journalism from New York University, and a bachelor's degree in physics from the University of Hawaii. His work covers all areas of science, from the quirky mating behaviors of different animals, to the drug and alcohol habits of ancient cultures, to new advances in solar cell technology. On a more personal note, Joseph has had a near-obsession with video games for as long as he can remember, and is probably playing a game at this very moment.
The maximal activity of the adrenal cortex is between 2 am and 8 am, and it is minimal between 4 pm and midnight. Exogenous corticosteroids suppress adrenocorticoid activity the least when given at the time of maximal activity (am) for single dose administration. Therefore, it is recommended that prednisone be administered in the morning prior to 9 am and when large doses are given, administration of antacids between meals to help prevent peptic ulcers. Multiple dose therapy should be evenly distributed in evenly spaced intervals throughout the day.
Psychological reactions such as insomnia and irritability are common, but they are certainly not the only prednisone side effects. Some of these adverse consequences, such as osteopenia, diabetes or glaucoma, appear only after long-term use of the drug. Others, such as confusion, high blood pressure or a drop in potassium, can occur on a shorter time frame. The most serious prednisone side effects that may happen within a week or two of use are dangerous blood clots (deep vein thrombosis), blood infections (sepsis) and bone fractures (Waljee et al, BMJ , April 12, 2017 ). We offer a more complete list below.
