Prednisolone Pediatric Dose Calculator

The standard dose for an acute asthma exacerbation in children is 1–2 mg/kg/day, with most guidelines recommending approximately 1.5 mg/kg/day. The maximum daily dose is typically capped at 60 mg. A typical treatment course lasts 3–5 days, and tapering is generally not required for short courses under 7 days.

Prednisolone is the active metabolite of prednisone. In children, prednisolone is generally preferred because it is available as a palatable liquid formulation and does not require hepatic conversion. The dosing is equivalent milligram-for-milligram, but prednisolone has better bioavailability in young children whose liver metabolism may be immature.

The two most commonly available concentrations are 15 mg/5 mL (3 mg/mL) and 25 mg/5 mL (5 mg/mL). The 15 mg/5 mL formulation, such as Orapred, is more commonly prescribed for younger children because smaller volumes are easier to measure accurately. The 25 mg/5 mL concentration is useful for older or heavier children to reduce the total volume needed.

Short courses of 3–5 days are generally considered safe and do not require tapering. Courses extending beyond 7–10 days may require a gradual taper to avoid adrenal suppression. Long-term use (weeks to months) requires close monitoring for side effects including growth suppression, immune suppression, and metabolic changes. Always follow physician guidance for duration.

Yes, prednisolone can and should be given with food or milk to reduce gastrointestinal irritation. The liquid formulation can be mixed with a small amount of juice or flavored drink to improve palatability, though it should not be mixed with large volumes of liquid as the child may not consume the full dose.

For croup, the recommended prednisolone dose is 1 mg/kg as a single dose, with a maximum of 60 mg. This is typically administered once and may be repeated once the following day if symptoms persist. Dexamethasone at 0.6 mg/kg is an alternative, but prednisolone is used when dexamethasone is unavailable or when a liquid formulation is preferred.

For most indications including asthma and croup, the entire daily dose is given once in the morning to mimic the body's natural cortisol rhythm and minimize sleep disruption. For nephrotic syndrome or higher doses, some protocols divide the daily dose into two doses (morning and evening) to improve tolerability. Follow your prescriber's specific instructions.

Common short-term side effects include increased appetite, mood changes (irritability or hyperactivity), trouble sleeping, and stomach upset. These typically resolve after the medication is discontinued. Long-term side effects with extended use include weight gain, growth suppression, increased infection risk, elevated blood sugar, and bone density changes.

This calculator is designed for pediatric patients generally weighing 1 kg and above. Neonatal dosing may require different considerations including adjusted body weight, renal maturity, and specific neonatal protocols. For neonates, always consult a neonatologist or pediatric pharmacist for individualized dosing.

The maximum daily dose depends on the indication. For asthma and general anti-inflammatory use, the cap is typically 60 mg/day. For nephrotic syndrome, some protocols allow up to 80 mg/day during induction. These maximums apply regardless of the child's weight — once the weight-based calculation exceeds the cap, the maximum dose is used instead.
