Corticosteroids, commonly known as steroids, are powerful anti-inflammatory medicines used to treat a vast range of conditions, from asthma and severe allergies to autoimmune disorders. While the body produces its own steroids naturally in the adrenal glands, synthetic versions are often prescribed to reduce inflammation and dampen an overactive immune system.
Steroids are versatile treatments used across almost every medical specialty. Common conditions treated include:
Respiratory: Asthma, COPD, and croup.
Autoimmune: Lupus (SLE), Rheumatoid Arthritis, and Multiple Sclerosis (MS) relapses.
Digestive: Crohn’s disease and Ulcerative Colitis.
Dermatological: Eczema and severe rashes.
Emergent Infections: Severe COVID-19 and certain types of pneumonia.
While many steroids exist, these ten are the most frequently prescribed in clinical practice, spanning tablets, inhalers, and topical creams.
1. Prednisolone (The most common steroid tablet)
Prednisolone is the “gold standard” oral steroid. It is used for a variety of inflammatory conditions and is typically the first choice for short-term “rescue” courses.
2. Dexamethasone
A highly potent steroid often used for severe allergic reactions, brain swelling (oedema), and as a key treatment for hospitalised COVID-19 patients.
3. Hydrocortisone
Available as a cream for skin conditions, an injection, or a tablet. In tablet form, it is frequently used for adrenal insufficiency (replacing the hormones the body can’t make).
4. Methylprednisolone
Often administered via IV in hospitals for acute flare-ups of MS or severe rheumatoid conditions, though it also comes in tablet form.
5. Beclometasone
Most commonly found in “preventer” inhalers for asthma or as a nasal spray for hay fever and allergic rhinitis.
6. Fluticasone
A common ingredient in modern inhalers (like Flixotide) and nasal sprays (like Flixonase) used to manage chronic respiratory inflammation.
7. Budesonide
Used frequently for inflammatory bowel disease (as a tablet or rectal foam) and as an inhaled treatment for asthma.
8. Betamethasone
A potent topical steroid found in creams and ointments used to treat stubborn skin conditions like psoriasis or severe eczema.
9. Deflazacort
A specialized glucocorticoid often used in the long-term management of Duchenne Muscular Dystrophy.
10. Fludrocortisone
Unlike the others, this is a mineralocorticoid. It is primarily used to help the body maintain salt and water balance in patients with Addison’s disease or low blood pressure.
To maximise effectiveness and minimize stomach irritation, follow these guidelines:
Timing: Take oral steroids in the morning with or after breakfast.
Consistency: If you miss a dose, take it as soon as you remember. However, never double your dose to catch up.
The Golden Rule: Never stop taking steroids suddenly if you have been on them for more than three weeks.
⚠️ Warning: Adrenal Insufficiency
If you stop long-term steroids abruptly, your adrenal glands may fail to restart hormone production. This can lead to adrenal crisis, characterized by extreme fatigue, vomiting, dizziness, and low blood pressure. Always follow a doctor’s tapering schedule.
Side effects are rare with short courses (under 3 weeks). However, long-term or high-dose use can lead to:
Short-Term Side Effects
Increased appetite and weight gain.
Insomnia and mood swings (irritability or aggression).
Blurred vision.
Long-Term Side Effects
Physical Changes: Central obesity (weight gain around the middle), “moon face,” and stretch marks (striae).
Bone & Skin Health: Osteoporosis (weak bones) and thin, easily bruised skin.
Metabolic Issues: New-onset Diabetes or high blood pressure.
Immune System: Increased susceptibility to infections like shingles or chickenpox.
Steroids are life-saving medications, but they require careful management. Whether you are using a Prednisolone tablet or a Fluticasone inhaler, the goal is always to use the lowest effective dose for the shortest possible time.
