Prednisone: uses, dosing, side effects & brands

How prednisone is dosed

From the FDA label for Prednisone (application ANDA085162). Other prednisone products — different forms, different strengths — are dosed differently. Follow the label for the one you were prescribed.

Gastric irritation may be reduced if taken before, during, or immediately after meals or with food or milk. 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. Dietary salt restriction may be advisable in patients. Do not stop taking this medicine without first talking to your doctor. Avoid abrupt withdraw of therapy. The initial dosage of prednisone may vary from 5 mg to 60 mg per day, depending on the specific disease entity being treated. In situations of less severity lower doses will generally suffice, while in selected patients higher initial doses may be required. The initial dosage should be maintained or adjusted until a satisfactory response is noted. If after a reasonable period of time there is a lack of satisfactory clinical response, prednisone should be discontinued and the patient transferred to other appropriate therapy. IT SHOULD BE EMPHASIZED THAT DOSAGE…

How long prednisone stays in your system

The elimination half-life of prednisone is roughly 2 to 4 hours (short). Prednisone is a prodrug: the liver completely converts it to prednisolone, its active form. The FDA prednisolone label gives prednisolone a plasma elimination half-life of 2 to 4 hours, and the FDA RAYOS (prednisone) label states the terminal half-life of prednisone itself is 2 to 3 hours — so the active metabolite is NOT materially longer. Note that this blood half-life is much shorter than the drug's anti-inflammatory/biological effect, which lasts far longer (adrenal suppression persists roughly a day or more after a dose). Prednisolone is 70 to 90 percent protein-bound and cleared by the liver, so clearance can vary with liver function.

Half-life is how long the body takes to clear half a dose. It is not the same as how long a drug test can detect it, and it varies with age, kidney and liver function.
