Prednisolone is a steroid used for many conditions — asthma flares, allergic reactions, rheumatic disease, and more. Doses vary a lot depending on the problem, how severe it is, and whether you need a short burst or long-term therapy. Below are practical, commonly used ranges and safety tips to help you understand what your doctor might prescribe.
Adult short courses (flare, asthma exacerbation, allergic reaction): often 20–60 mg once daily for a few days to a week. A typical single-course example for asthma or severe allergic flare is 40 mg daily for 3–7 days.
Rheumatic or inflammatory diseases: maintenance doses are usually lower — often 5–20 mg daily. For a bad flare, doctors may temporarily increase to 40–60 mg daily, then reduce as symptoms improve.
Adrenal insufficiency or replacement therapy: physiologic replacement doses are much lower than anti-inflammatory doses. Typical replacement dosing with prednisolone is usually in the low single-digit mg range per day, adjusted by a clinician.
Children: pediatric dosing is commonly calculated by weight. For short bursts many clinicians use around 1–2 mg/kg once daily (up to a defined adult maximum), but exact doses depend on the condition and the child’s age/weight.
Topical, inhaled, or eye drop forms: these use different dosing schedules that are local rather than systemic. Follow the product instructions or the exact plan your prescriber gives you.
Take prednisolone in the morning with food to reduce stomach upset and mimic your body’s cortisol rhythm. If you’re on more than a short course (longer than 1–2 weeks), don’t stop suddenly — tapering is usually needed to avoid adrenal suppression. Your doctor will give a taper plan based on dose and duration.
Watch for common side effects: increased appetite, weight gain, mood shifts, trouble sleeping, higher blood sugar, and higher blood pressure. Long-term use raises risks for bone thinning, infections, cataracts, and muscle weakness — your clinician may order blood tests, bone checks, or suggest calcium and vitamin D if you need prolonged therapy.
Interactions and precautions: tell your provider about blood thinners, diabetes meds, certain antifungals, and recent live vaccines. If you have diabetes, high blood pressure, or infections, your dose plan may change.
If you’re pregnant, breastfeeding, or have serious health issues, talk openly with your prescriber — they’ll weigh the benefits and risks and pick the safest dose. Always follow the exact prescription your clinician gives. If symptoms change or you notice worrying side effects, contact them right away.
