Are Cortisol and Cortisone the Same Thing?

If you have ever received a cortisone injection for inflammation or seen cortisone cream at the pharmacy, you may have wondered how it connects to all those conversations about cortisol and stress. The names sound almost identical. The chemistry overlaps. But they are not the same thing, and the distinction matters more than most people realize.

The Chemistry Behind Both Hormones

Cortisol (chemical name: hydrocortisone) and cortisone are both glucocorticoids, a class of steroid hormones derived from cholesterol. They share a nearly identical molecular structure, differing by just one oxygen atom.

Cortisol has a hydroxyl group (OH) at the 11-beta carbon position on its molecule. Cortisone has a ketone group (C=O) at the same position. This seemingly small difference completely changes how each molecule behaves in the body.

That single oxygen atom determines whether the hormone is active or inactive.

Cortisol: The Active Stress Hormone

Cortisol is produced by the adrenal cortex in response to signals from the hypothalamus and pituitary gland via the HPA axis. It is the biologically active form of the hormone.

Cortisol can bind directly to glucocorticoid receptors throughout the body, which is how it produces its wide-ranging effects on metabolism, inflammation, immune function, blood sugar, sleep, and the stress response.

It is present in the blood, saliva, and urine, and is what lab tests measure when evaluating your stress hormone status. For more on what elevated cortisol actually does to your body over time, see our post on the hidden cost of high cortisol on your body and budget.

Cortisone: The Inactive Companion

Cortisone occurs naturally in the body as an inactive form of cortisol. It does not bind to glucocorticoid receptors on its own. To have any physiological effect, cortisone must be converted back into cortisol by an enzyme called 11-beta-hydroxysteroid dehydrogenase type 1 (11beta-HSD1).

This conversion happens primarily in the liver and in fat tissue. The enzyme essentially reactivates cortisone by converting it back to the active cortisol form where it is needed.

In a healthy body, cortisol and cortisone exist in a dynamic balance. The body converts between the two forms as a way of regulating how much active cortisol is available in different tissues at any given time.

How the Body Converts Between the Two

The 11beta-HSD enzyme system acts like a local volume control for cortisol in specific tissues.

In tissues where cortisol activity needs to be limited, such as in the placenta during pregnancy, the enzyme converts active cortisol into inactive cortisone. In tissues where cortisol activity needs to be amplified, such as in the liver or certain fat cells, it converts inactive cortisone back into active cortisol.

This local regulation is separate from the overall systemic cortisol level and helps explain why cortisol's effects can vary significantly in different parts of the body, even when blood levels appear normal.

Interestingly, research has found that 11beta-HSD1 activity is increased in visceral fat tissue, which may contribute to why chronic stress and elevated cortisol are associated with abdominal fat accumulation.

Medical Uses of Cortisone

In the pharmaceutical world, cortisone refers to a synthetic glucocorticoid medication used primarily for its powerful anti-inflammatory effects.

Cortisone injections are used to treat inflammatory conditions including arthritis, tendinitis, bursitis, and joint pain. Topical cortisone creams are applied to the skin for inflammatory skin conditions such as eczema and contact dermatitis. Oral cortisone medications are used in some cases of severe inflammation or autoimmune conditions.

When injected or applied topically, synthetic cortisone is converted to active cortisol locally at the treatment site, producing the anti-inflammatory effect. Systemic absorption varies depending on the form, dose, and location of use.

How Cortisone Treatments Affect Your Cortisol Levels

This is where the clinical relevance becomes important for everyday health decisions.

Cortisone injections and topical cortisone, when used occasionally and at low doses, typically have minimal systemic effects on cortisol levels. However, repeated cortisone injections, high-dose oral cortisone, or prolonged use of potent topical cortisone can suppress the HPA axis.

This happens because the synthetic glucocorticoid signals to the hypothalamus and pituitary gland that enough cortisol is present, reducing the body's own cortisol production. Abruptly stopping cortisone treatment after extended use can result in cortisol insufficiency, which is why these medications are tapered rather than stopped suddenly.

If you are currently receiving cortisone treatment and are concerned about its effects on your natural cortisol levels, this is an important conversation to have with your prescribing physician.

What This Means for Women Managing Stress Naturally

Understanding the cortisol-cortisone relationship reinforces something important: your body already has sophisticated mechanisms for regulating how much active cortisol is available in different tissues.

Supporting these regulatory systems through healthy lifestyle habits, quality sleep, balanced nutrition, and effective stress management gives your body the tools it needs to maintain this balance naturally. Our post on the best nighttime routines to naturally lower cortisol before bed offers practical guidance on supporting overnight hormonal regulation.

For women looking to support their stress response with natural supplements, adaptogens like ashwagandha work upstream in the HPA axis rather than directly manipulating cortisol or cortisone chemistry. This makes them a gentler, more systemic approach to stress management.

Calmfort gummies combine ashwagandha with L-theanine and taurine to support natural relaxation and a balanced stress response. They are vegan, sugar-free, non-GMO, gluten-free, and non-habit-forming, produced in an FDA-approved, GMP-certified facility, and trusted by over 5,000 women across the U.S.

If you are curious whether natural adaptogenic support might complement your wellness routine, it is worth exploring. And as always, if you are currently using prescription cortisone, discuss any supplement additions with your healthcare provider.

Frequently Asked Questions

Is cortisol the same as cortisone? No. Cortisol is the biologically active form of the hormone, produced naturally by the adrenal glands. Cortisone is the inactive form, which must be converted to cortisol by an enzyme to exert effects. They are structurally nearly identical but functionally different.

Can cortisone shots affect my cortisol levels? Occasional cortisone injections typically have limited effects on systemic cortisol levels. However, repeated high-dose cortisone treatments can suppress the HPA axis and reduce your body's own cortisol production. Always discuss this with your doctor if you receive regular cortisone injections.

Does cortisone cream affect stress hormones? When used as directed at appropriate doses on a limited area of skin, topical cortisone cream has minimal systemic absorption and is unlikely to significantly affect cortisol levels. Prolonged use on large areas or under occlusion can increase absorption and potential systemic effects.

Why is cortisol sometimes called hydrocortisone? Hydrocortisone is simply the pharmaceutical name for cortisol. When used as a medication, cortisol is called hydrocortisone to distinguish it as a synthetic preparation. The biology is identical to the cortisol your adrenal glands produce naturally.

What is the difference between glucocorticoids and cortisol? Glucocorticoids are a class of steroid hormones. Cortisol is the primary glucocorticoid produced by the human body. Synthetic glucocorticoids, such as prednisone, dexamethasone, and cortisone, are medications that mimic or modify the effects of cortisol.
