How does Prednisolone work?
Prednisolone is the biologically active form of prednisone. It suppresses inflammation by blocking the production of inflammatory chemicals (prostaglandins, leukotrienes, cytokines) and inhibiting immune cell activity.

Frequently asked questions
What is prednisolone used for?
Prednisolone treats inflammatory, allergic, and autoimmune conditions — everything from severe asthma and arthritis to lupus and inflammatory bowel disease. It is also used as eye drops for eye inflammation.
What is the difference between prednisolone and prednisone?
They are essentially the same drug. The liver converts prednisone into prednisolone, which is the active form. Prednisolone is preferred when liver function is impaired (the liver can't convert prednisone efficiently) and for children. Otherwise they are interchangeable.
Why must prednisolone be tapered?
Long-term use suppresses the adrenal glands, which produce cortisol. Stopping suddenly leaves the body without enough cortisol for stress response — adrenal crisis is life-threatening. Tapering allows the glands to recover gradually.
Can prednisolone eye drops affect the whole body?
Yes — although small, some steroid from eye drops is absorbed systemically. Long-term steroid eye drop use can increase eye pressure (glaucoma risk) and cause cataracts, and in some cases affect adrenal function. Always use the minimum effective dose.
How quickly do prednisolone tablets work?
Prednisolone starts suppressing inflammation within hours. Most people notice significant symptom improvement within 1–4 days of starting a course for acute conditions like asthma flare-ups or allergic reactions.
