Prednisone is a synthetic glucocorticoid that has a significant role in managing various autoimmune and inflammatory conditions. In this blog post, we will delve into the various aspects of prednisone, including its mechanism of action, the conditions it is used to treat, and how it is dosed in the world of rheumatology.

Understanding Prednisone

Prednisone is a synthetic glucocorticoid, which means it is a man-made version of cortisol, a naturally occurring hormone produced by the adrenal glands. Cortisol is involved in various aspects of our body’s function, from cardiovascular and metabolic systems to immune response and maintaining homeostasis.

The synthetic glucocorticoids, including prednisone, are designed to mimic the effects of cortisol in the body.

Prednisone is commonly used in rheumatology clinics, where it is prescribed to manage the symptoms of autoimmune and inflammatory conditions. The synthetic glucocorticoids come in various forms and potencies, including hydrocortisone, prednisone, and methylprednisolone.

These medications can be administered orally, topically, or intravenously, depending on the patient’s needs and the specific condition being treated.

Conditions Treated with Prednisone

Prednisone and other synthetic glucocorticoids are used to treat a wide range of conditions, from adrenal insufficiency to inflammatory conditions that cause damage to the body. Inflammatory conditions that can be treated with prednisone include asthma, severe infections, brain swelling, vertigo, chronic coughs, sinus infections, rashes, and autoimmune conditions.

In rheumatology, prednisone is used to manage autoimmune conditions that have escalated to a point where they cause severe health issues or significantly impact the patient’s quality of life.

In these cases, prednisone acts as a “rope” to pull patients back from the “inflammatory cliff” they find themselves on. For example, prednisone may be prescribed to shut down inflammation quickly and effectively in patients with lupus or other conditions causing severe joint inflammation and pain.

Dosing Prednisone in Rheumatology

In rheumatology, the dosing of prednisone is often based on the patient’s body weight. A high dose of prednisone is typically considered as 1 milligram of prednisone per kilogram of body weight per day.

In general terms, this equates to around 60 milligrams of prednisone daily, although higher body weight may require higher doses.

A moderate dose of prednisone is usually half of the high dose, or 0.5 milligrams per kilogram of body weight per day, translating to around 20 to 40 milligrams daily. Low-dose prednisone typically falls between 2.5, 5, or 10 milligrams per day.

Understanding Dosage and Side Effects:

The side effects of prednisone are dependent on the dosage level and the duration of treatment. It’s essential to know whether you are on a high, moderate, or low dose to assess your risk for certain side effects.

Prednisone as a Rope

Think of prednisone as a rope that is thrown to save someone from the “inflammatory cliff.” This cliff represents a point where inflammation has become so severe that it significantly impacts a person’s quality of life or their organs.

Once the individual is pulled away from the cliff and onto stable ground, a long-term treatment strategy can be developed.

Prednisone as a Bridge

In many cases, prednisone should not be part of a long-term treatment strategy. However, it can serve as a bridge while waiting for long-term medications to take effect. This helps to maintain stability and control inflammation until the long-term treatment becomes effective.

Tapering Off Prednisone

It’s crucial to discuss your prednisone tapering strategy with your doctor. Tapering off prednisone is necessary because abruptly stopping can lead to severe problems, including death. This is due to the body’s dependency on synthetic cortisol and the time it takes for the adrenal glands to start producing cortisol again.

For short-term use of prednisone (five to seven days), tapering may not be necessary. However, for those who have been on the medication for longer periods, tapering is essential. It’s also worth noting that it can take some time for the adrenal glands to return to full function, which may contribute to lingering fatigue or brain fog.


Understanding the role of prednisone in managing autoimmune and inflammatory conditions is crucial for patients. Be sure to ask your doctor about the strategy for tapering off prednisone and stay tuned for our upcoming blog post on prednisone side effects.
