Prednisolone: Uses, Dosage, Side Effects, and Safety
Prednisolone is a steroid medicine used to reduce inflammation and suppress the immune system. Doctors prescribe it for asthma flare-ups, allergic reactions, some autoimmune conditions, and certain eye or skin problems. It comes as tablets, liquid, eye drops, and injections, so the exact dose and choice depend on your condition and how fast relief is needed.
How prednisolone works matters.
It mimics hormones your body makes naturally to fight stress and inflammation. That helps when your immune system is overactive. Short courses—usually a few days to a couple of weeks—often help quickly. Long-term use can control chronic conditions but raises more safety concerns, so doctors aim for the lowest effective dose.
Dosing is not one-size-fits-all. For adults, short courses might be 5 to 60 mg per day depending on the problem. For children doses are weight-based. If your doctor prescribes daily or alternate-day therapy, follow the exact schedule. Never change dose or stop suddenly without medical advice—tapering over days or weeks prevents withdrawal and adrenal insufficiency.
Side effects vary by dose and duration.
Short-term side effects can include irritability, trouble sleeping, increased appetite, and mild fluid retention. With long-term use you might see higher blood sugar, weight gain, thinning skin, easy bruising, bone loss, and increased infection risk. Eye pressure and cataracts are possible after months or years. Ask your doctor about bone-protecting measures if you’ll be on steroids long-term.
Interactions and precautions are common. Prednisolone can raise blood sugar, so people with diabetes need closer monitoring. It can reduce the effectiveness of some vaccines, especially live vaccines, so timing matters. Tell your doctor about all medications—blood thinners, certain antifungals, and some antibiotics can interact. If you have active infection, unhealed wounds, or certain psychiatric conditions, discuss risks before starting.
Practical tips that help. Carry a steroid card or note listing your dose and prescribing doctor in case of emergency. If you develop fever or signs of infection while on prednisolone, call your clinician promptly. Avoid skipping doses; take morning doses with food to reduce stomach upset. Plan for vaccination and dental procedures with your healthcare team so timing and antibiotic coverage are handled correctly.

Questions specific to your health are best handled by your prescriber. If side effects bother you or your condition changes, contact them quickly. Steroids like prednisolone are powerful tools when used carefully.
Pregnancy, breastfeeding, and children need special attention — tell your obstetrician or pediatrician before using prednisolone. Traveling? Bring enough medication, the prescription, and store it properly; some countries restrict steroids. Keep a medication list and review it yearly with your provider so you can reduce dose when possible and check bone health, eye exams, and vaccination status. Ask for written plans for tapering and side effect monitoring regularly.
