Prednisolone is a corticosteroid used to reduce inflammation and calm overactive immune responses. Doctors prescribe it for asthma attacks, allergic reactions, some autoimmune diseases, certain skin conditions, and flare-ups of chronic problems. It works quickly and can feel life-changing when inflammation needs to be stopped fast.
Prednisolone comes as tablets, a liquid, and eye or ear drops. Follow your doctor’s instructions exactly. For short courses (a few days), many people take a fixed dose and stop. For longer courses, doctors usually taper the dose down slowly to avoid withdrawal and adrenal suppression. Never stop a multi-week course abruptly unless advised by your doctor.
Take prednisolone with food to reduce stomach upset. Try to take it in the morning if possible — this matches your body’s natural steroid rhythm and can cut insomnia. Keep a list of your doses and bring it to appointments. If you miss one dose, follow your prescription label or call your clinic for specific advice.
Short-term side effects can include increased appetite, mood swings, trouble sleeping, and higher blood sugar. These often settle when treatment ends. Long-term or high-dose use raises the risk of bone loss, weight gain, high blood pressure, higher infection risk, cataracts, and muscle weakness. People with diabetes should monitor blood sugar more often while taking prednisolone.
If you feel new or severe symptoms — intense stomach pain, sudden weight gain, shortness of breath, severe mood changes, signs of infection like fever — contact your doctor right away. Also tell any healthcare provider you see that you’re taking prednisolone; it matters for surgery and vaccines.
Prednisolone is closely related to prednisone. Prednisone converts to prednisolone in the liver. Some people with liver problems are given prednisolone directly because it’s already active. Your doctor will pick the best option based on your health and other medicines.
Drug interactions matter. Blood thinners, diabetes meds, certain vaccines, and some heart or seizure drugs can interact with prednisolone. Share a full medication list with your prescriber, including over-the-counter drugs and supplements.
Practical tips: get calcium and vitamin D if you’ll be on steroids for months. Ask about bone-sparing drugs if you have osteoporosis risk. Carry a steroid card or note in your wallet stating you use prednisolone — emergency staff need to know. Avoid live vaccines while on high doses. Try to keep stress low and sleep well to support recovery.
Prednisolone is powerful and useful when used correctly. It can stop dangerous inflammation but needs respect: follow dosing, watch for side effects, and stay in touch with your healthcare team. If you have questions about dosing, tapering, or interactions, ask your doctor or pharmacist — they can tailor advice to your situation.
