Corticosteroids

Corticosteroids are a class of medications that are widely used in healthcare to help reduce inflammation, manage immune system activity, and treat many short-term and long-term medical conditions. There are two main classes of corticosteroids, glucocorticoids and mineralocorticoids, which are different from anabolic steroids used for muscle building. Corticosteroids are designed to closely mimic natural steroid hormones, such as cortisol, that are produced by the adrenal glands.

Corticosteroids can be life-saving in certain situations, such as severe allergic reactions or adrenal insufficiency, and they are also commonly used for chronic conditions like rheumatoid arthritis, lupus, asthma, and skin conditions. Depending on the type and dose, corticosteroids may be used for short-term relief or long-term management under close medical supervision.

Corticosteroids are steroid hormones made in a laboratory to act like cortisol, a hormone naturally produced by the adrenal cortex. Cortisol plays an important role in regulating inflammation, immune responses, blood sugar, and how the body responds to stress.

Prescription corticosteroids are used to treat a wide range of conditions by helping control inflammation and calming an overactive immune system. They come in many forms, including oral corticosteroids, inhalers, injections, eye drops, skin creams, and intravenous formulations.

Corticosteroids work by affecting how the immune system responds to injury, illness, or inflammation. They help reduce swelling, redness, and irritation by limiting the release of substances in the body that trigger inflammation. Corticosteroids also influence how the body uses carbohydrates, fats, and proteins, which is why changes in blood sugar and weight gain can occur, especially with high doses or long-term corticosteroid use.

There are several types of corticosteroids, and they vary based on strength, duration of action, and route of administration. Common types of corticosteroids include:

Prednisone (Rayos).

Prednisolone (Omni Pred, Pred Forte).

Hydrocortisone (Hydrocort, Cortef).

Dexamethasone (Maxidex).

Methylprednisolone (Medrol, Depo-Medrol).

Cortisone.

Mometasone (Nasonex).

Triamcinolone (Kenalog).

Corticosteroids are used to treat many medical conditions that involve inflammation or immune system activity. These include:

• Autoimmune diseases such as rheumatoid arthritis and lupus.
• Asthma and other breathing conditions are treated with inhaled corticosteroids.
• Skin conditions such as eczema and allergic rashes.
• Severe allergic reactions.
• Adrenal insufficiency.
• Certain eye conditions are managed in ophthalmology.
• Gastrointestinal conditions involving inflammation.
• Wound healing complications related to inflammation.
• Some cancers as part of a combination therapy.

Side effects of corticosteroids depend on the dose, duration of treatment, and how the medication is taken. Common side effects include:

• Weight gain.
• Mood swings or mood changes.
• Increased blood sugar.
• Fluid retention.
• Increased appetite.
• Muscle weakness.
• Trouble sleeping.
• Increased risk of infections.

Long-term corticosteroid use or high doses may increase the risk of more serious side effects, including:

• Osteoporosis.
• Cataracts.
• Glaucoma.
• High blood pressure.
• Cushing syndrome.
• Adrenal insufficiency if stopped suddenly.
• Delayed wound healing.

These are not all of the possible side effects of corticosteroids. You should always seek medical advice from your healthcare provider for any questions or concerns about your medical condition or treatment. Read all patient information, medication guides, or drug information sheets that come with this medication. You can also report adverse effects to the Food and Drug Administration at www.fda.gov/medwatch or 1-800-FDA-1088.

Although these medications are generally well-tolerated and safe, there are certain warnings, precautions, and drug interactions you should be aware of. Corticosteroids should always be used exactly as prescribed and monitored by a healthcare provider, especially during long-term therapy.

Warnings

Before starting corticosteroids, it is crucial to discuss any existing health conditions with your healthcare provider. You should be sure that your healthcare provider is aware of all your medical conditions, including if you have:

• Diabetes or problems with blood sugar control.
• High blood pressure.
• Osteoporosis or a history of bone fractures.
• Eye conditions such as cataracts or glaucoma.
• A history of infections or a weakened immune system.
• Gastrointestinal conditions such as ulcers.
• Adrenal gland disorders.
• Mental health conditions or mood disorders.
• Your healthcare provider may recommend calcium and vitamin D supplements during long-term corticosteroid therapy to help protect bone health.

Contraindications

Corticosteroids may not be appropriate for everyone. Contraindications may include:

• Known hypersensitivity or severe allergic reaction to corticosteroids.
• Certain untreated infections, especially systemic fungal infections.

Drug interactions

When corticosteroids are taken with other prescription drugs, over-the-counter medications, vitamins, and supplements, they may change how they work or increase the frequency or severity of side effects. Make sure that you tell your healthcare professional about anything that you are taking to avoid any negative drug interactions, including:

• Nonsteroidal anti-inflammatory drugs (NSAIDs) may increase gastrointestinal irritation.
• Certain vaccines, as corticosteroids may reduce immune response.
• Supplements that affect blood sugar, due to an increased risk of hyperglycemia.
