What is Prednisone (Deltasone)?
Prednisone is a corticosteroid that reduces inflammation and calms an overactive immune response. It's used for a wide range of conditions, including severe allergic reactions, asthma flares, autoimmune disease flares, and other inflammatory conditions — the specific use determines the dose and length of treatment. Short courses are typically tapered down gradually rather than stopped abruptly, especially after more than a week or two of use.
Broad immune suppression
A corticosteroid that reduces inflammation and calms an overactive immune response across the whole body.
Used across many conditions
Prescribed for everything from allergic reactions to autoimmune flares to severe asthma, depending on the situation.
Tapered, not stopped abruptly
Longer courses are tapered down gradually rather than stopped suddenly, to avoid withdrawal effects on the adrenal glands.

Frequently asked questions
What is prednisone used for?
Prednisone is a corticosteroid used across many conditions — allergic reactions, autoimmune flares, severe asthma, and more — to reduce inflammation and calm an overactive immune response, often quickly enough to provide fast relief during a flare. This makes it especially useful for situations where waiting weeks for relief isn't an option.
How is my prednisone dose decided?
Dose and length of treatment depend on the condition being treated and its severity — short bursts for acute flares, longer tapering courses for chronic conditions needing sustained control. Your clinician tailors both to your specific situation. Your clinician will explain the specific tapering schedule that applies to your particular course.
How quickly does prednisone work?
It often works within hours to a day or two for acute inflammation, making it useful for fast symptom relief compared to slower-acting anti-inflammatory options that can take weeks to build up their full effect. These effects are usually mild and temporary, resolving once the course of treatment ends.
Why do I need to taper off prednisone instead of stopping suddenly?
Longer courses suppress your body's natural cortisol production over time; stopping abruptly can cause withdrawal symptoms and adrenal insufficiency. Tapering gives your adrenal glands time to resume normal function safely before the medication is fully stopped. Your clinician will monitor for these specifically if you need a longer or repeated course.
What side effects are associated with prednisone?
Increased appetite, mood changes, and trouble sleeping are common even with short courses of treatment. Longer-term use carries additional risks like bone thinning and elevated blood sugar, both of which your clinician will monitor closely during any extended or repeated course of treatment.
