Corticosteroid Pregnancy: 88% of prednisolone is inactivated crossing the placenta. No evidence of increased congenital abnormality in man, but prolonged or repeated administration in pregnancy may increase the risk of intra-uterine growth retardation; cataracts have been observed in infants of mothers on long-term prednisolone. Prescribe only when benefits to mother and child outweigh the risks. Excreted in small amounts in breast milk (5–25% of serum concentration) — if maternal doses above 40 mg/day are prescribed, monitor the infant for adrenal suppression (§4.6).

Prednisolone (Systemic)

Brand names: Deltacortril, Pred Forte

Prednisolone is an oral glucocorticoid used across many inflammatory, allergic, respiratory and autoimmune conditions.

Auto-extracted from the source labelling — not yet independently clinician-verified. These values were distilled from the UK SPC (or the US label where noted) but have not had a clinician sign-off. Confirm against the current SmPC before prescribing.

Adult dose

Dose: Initial dosage 5 mg to 60 mg daily, depending on the disorder being treated; divided daily dosage is usually used. Reduce gradually to the lowest dose that maintains an adequate clinical response
Route: Oral
Frequency: Daily, usually in divided doses (a single morning dose on alternate days or at longer intervals is acceptable therapy for some patients and minimises pituitary-adrenal suppression)
Source: UK SPC §4.2 for Prednisolone 1 mg Gastro-resistant Tablets (Deltacortril). Indication-specific initial doses given as guidance only: allergic and skin disorders 5–15 mg daily; collagenosis 20–30 mg daily (higher if more severe); rheumatoid arthritis usual initial dose 10–15 mg daily, then lowest maintenance dose compatible with tolerable symptomatic relief; blood disorders and lymphoma initial 15–60 mg daily with reduction after adequate clinical/haematological response (higher doses may be necessary to induce remission in acute leukaemia). Acute or severe disease may require initial high-dose therapy with reduction to the lowest effective maintenance dose as soon as possible; dosage reductions should not exceed 5–7.5 mg daily during chronic treatment. Withdrawal: in patients who have received more than a physiological dose (approximately 7.5 mg prednisolone or equivalent) for more than 3 weeks, withdrawal should not be abrupt; once a daily dose equivalent to 7.5 mg is reached, reduce more slowly to allow HPA-axis recovery. Abrupt withdrawal of up to 40 mg daily for 3 weeks or less is unlikely to cause clinically relevant HPA-axis suppression in most patients, but gradual withdrawal should still be considered after courses of 3 weeks or less in patients who have had repeated courses, a short course within one year of stopping long-term therapy, other reasons for adrenocortical insufficiency, doses above 40 mg daily, or repeated evening dosing. During prolonged therapy the dose may need to be temporarily increased during periods of stress or disease exacerbation. Children: although appropriate fractions of the adult dose may be used, dosage is usually determined by clinical response as in adults; alternate-day dosage is preferable where possible — no numeric paediatric dose is given in this SPC, verify against a children's formulary. Elderly: plan treatment, particularly long-term, bearing in mind the more serious consequences of common corticosteroid side-effects in old age. eMC §4.5 (interactions) was not captured in this bundle. Note: the US label in this bundle is PRED FORTE (prednisolone acetate ophthalmic suspension) — a different route and product; it has not been used for any dosing here.

Contraindications

  • Hypersensitivity to prednisolone or any of the excipients
  • Systemic infections, unless specific anti-infective therapy is employed
  • Ocular herpes simplex, because of possible perforation
  • Rare hereditary problems of galactose intolerance, Lapp lactase deficiency or glucose-galactose malabsorption (this formulation)

Side effects

  • Psychiatric reactions (common): irritability, depressed and labile mood, suicidal thoughts, psychotic reactions, mania, delusions, hallucinations, aggravation of schizophrenia, behavioural disturbance, anxiety, sleep disturbance, confusion and amnesia — severe reactions estimated at 5–6% in adults
  • Endocrine/metabolic: suppression of the hypothalamo-pituitary-adrenal axis, cushingoid facies, impaired carbohydrate tolerance with increased antidiabetic requirement, manifestation of latent diabetes, hyperglycaemia, weight gain, increased appetite, dyslipidaemia
  • Increased susceptibility to and severity of infections, opportunistic infections, recurrence of dormant tuberculosis, oesophageal candidiasis
  • Fluid and electrolyte: sodium and water retention, potassium loss, hypokalaemic alkalosis, negative nitrogen and calcium balance
  • Eye disorders: glaucoma, papilloedema, posterior subcapsular and nuclear cataracts
  • Nervous system: insomnia, dizziness, headache, vertigo, raised intracranial pressure with papilloedema, aggravation of epilepsy; very rarely calciphylaxis

Clinical monograph

How it works

A synthetic glucocorticoid that suppresses inflammation and immune responses through the glucocorticoid receptor.

Prescribing in practice

  • Do not stop a prolonged course abruptly — taper to avoid adrenal crisis.
  • Longer use brings a wide range of effects (hyperglycaemia, hypertension, osteoporosis, peptic-ulcer risk, mood disturbance, infection including reactivation, Cushingoid features, growth effects in children).
  • Consider gastroprotection, bone protection and infection precautions where appropriate.

Monitoring

Monitor glucose, blood pressure and weight; review bone health and eyes with long-term use; review mood and infection risk.

Counselling the patient

  • Take it in the morning, with food; never stop a longer course suddenly.
  • Carry a steroid card; report signs of infection or severe abdominal pain.
  • If you are not immune, contact with chickenpox or measles needs prompt advice.

Evidence & guidelines

A mainstay anti-inflammatory across specialties, balanced against well-characterised steroid harms.
