What is prednisone 20 mg used to treat?

Prednisone 20 mg is a corticosteroid used to treat a wide range of inflammatory and autoimmune conditions, and it can also be used in some cancer treatments and to replace cortisol in adrenal insufficiency. A 20 mg dose is a common starting amount for many moderate-to-severe conditions, though the exact dose and duration depend on the condition and how you respond.

Common indications include:
- Autoimmune and inflammatory diseases: rheumatoid arthritis, psoriatic/ankylosing spondylitis, systemic lupus erythematosus, vasculitis, inflammatory bowel disease (Crohn’s disease and ulcerative colitis), severe dermatitis or eczema, psoriasis.
- Respiratory and allergic conditions: asthma, COPD exacerbations, severe allergic reactions and hives.
- Eye and skin inflammation: uveitis, conjunctivitis, severe skin inflammation.
- Endocrine: adrenal insufficiency ( Addison’s disease) as a hormone replacement regimen.
- Neurologic and others: multiple sclerosis flare, certain brain/nerve inflammations.
- Cancer care: as part of chemotherapy regimens or to reduce inflammation/edema around tumors.
- Transplant medicine: to prevent organ rejection.

Important notes:
- Dosing is individualized; 20 mg may be started and then tapered based on response, duration, and the condition.
- Long-term use can cause side effects (weight gain, high blood sugar, bone loss, infections, mood changes, thinning skin, etc.) and may require tapering rather than stopping abruptly.
- It can interact with other drugs and isn’t appropriate for treating viral infections or some acute illnesses without a clinician’s guidance.
