Inhaled Corticosteroid (ICS) Pregnancy: Most results from prospective epidemiological studies and world-wide post-marketing data have not detected an increased risk of adverse effects for the foetus and newborn from inhaled budesonide during pregnancy; it is important for both foetus and mother to maintain adequate asthma treatment, and the benefit to the mother should be weighed against the risks to the foetus. Breast-feeding: budesonide is excreted in breast milk but at therapeutic doses no effects on the suckling child are anticipated - can be used during breast-feeding (estimated daily infant dose 0.3% of the daily maternal dose at 200 or 400 micrograms twice daily).

Budesonide (Inhaled)

Brand names: Pulmicort, Symbicort component

This is inhaled budesonide, a corticosteroid used as regular preventer therapy for asthma and as maintenance anti-inflammatory treatment in COPD, taken to reduce airway inflammation and exacerbations.

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: Steroid-naive patients and patients previously controlled on inhaled steroids - adults (including older people) and children/adolescents over 12 years of age: initial recommended dose 200-400 micrograms once or twice daily.
Route: Inhalation use (dry powder inhaler; Budelin Novolizer 200 micrograms per actuation)
Frequency: Once or twice daily. Twice-daily dosing should be used when starting treatment, during periods of severe asthma, and while reducing or discontinuing oral glucocorticosteroids. Once-daily dosing (taken in the evening) up to 800 micrograms may be used in adults, older people and children/adolescents over 12 years with mild to moderate asthma already controlled on twice-daily inhaled glucocorticosteroids (budesonide or beclometasone dipropionate).
Max: Maximum recommended dose in adults and children/adolescents over 12 years: 800 micrograms twice daily. Stated posology limits: 200-1600 micrograms daily for adults (including older people) and children/adolescents over 12 years.
STRENGTH- AND DEVICE-SPECIFIC: figures are from the SPC for Budelin Novolizer 200 micrograms per actuation inhalation powder; a 400 micrograms strength is available for the 400 microgram doses. If a patient is switched from an alternative inhalation device the dose should be reviewed and adjusted individually, considering the active substance, dose regimen and method of delivery. Adjust the dose until control is achieved, then titrate to the lowest dose maintaining effective control of asthma. If asthma control deteriorates (persistent respiratory symptoms, increased bronchodilator use), the inhaled steroid dose should be increased; patients on the once-daily regimen should be advised to double their dose, i.e. give the once-daily dose twice daily, and seek medical advice as soon as possible. A short-acting inhaled beta-2-agonist must be available at all times for relief of acute symptoms - budesonide is NOT indicated for acute dyspnoea or status asthmaticus. Transfer from oral steroids: start when the patient is in a relatively stable phase, give a high dose of inhaled budesonide combined with the previously used oral steroid dose for about 10 days, then reduce the oral steroid dose gradually (for example by 2.5 milligrams prednisolone or the equivalent each month) to the lowest possible level. Intended for long-term therapy; improvement may appear in 24 hours but 1-2 weeks of additional treatment may be needed for maximum benefit. Inhale before meals and rinse the mouth with water or brush the teeth after each inhalation to reduce oral candidiasis and hoarseness. PAEDIATRIC (from the same SPC, fixed microgram doses - no per-kg dose is stated): children 6-12 years initial recommended dose 200 micrograms twice daily or 200-400 micrograms once daily, maximum recommended 400 micrograms twice daily, posology limits 200-800 micrograms daily; once-daily dosing up to 400 micrograms may be used in children 6-12 years with mild to moderate asthma already controlled on twice-daily inhaled glucocorticosteroids. Not recommended below 6 years of age due to insufficient data on safety and efficacy. Children should only use this product under the supervision of an adult; growth should be monitored. Verify paediatric dosing against a children's formulary. Hepatic: in severe hepatic dysfunction elimination may be reduced and systemic availability increased - check HPA axis function at regular intervals. NOTE ON SOURCES: the openFDA record in this bundle is a US over-the-counter budesonide NASAL SPRAY (different route and indication) and was NOT used for this inhaled dose.

Contraindications

  • Hypersensitivity to the active substance budesonide or to the excipient lactose monohydrate (which contains small amounts of milk proteins)

Side effects

  • Common: oropharyngeal candidiasis
  • Common: hoarseness, cough, throat irritation; oral mucosal irritation
  • Uncommon: depression, anxiety, tremor; rare restlessness, nervousness, behavioural changes (predominantly in children); not known - sleep disorders, psychomotor hyperactivity, aggression
  • Uncommon: cataract, blurred vision; not known - glaucoma. Very rare: bone density decreased
  • Rare: adrenal suppression and growth retardation (systemic corticosteroid effects); immediate and delayed hypersensitivity reactions including angioneurotic oedema and anaphylactic reaction; bronchospasm, dysphonia

Interactions

  • eMC section 4.5 was not retrieved in this bundle. Section 4.4 begins a statement on concomitant use of ketoconazole and HIV protease inhibitors but the text was truncated at the source-fetch limit - the clinician must check the SPC for CYP3A4 inhibitor interactions before use.

Clinical monograph

How it works

The inhaled glucocorticoid binds airway glucocorticoid receptors to suppress local inflammation and reduce bronchial hyper-responsiveness.

Prescribing in practice

  • Most important: it is a preventer that must be used regularly and does not relieve an acute attack, so a short-acting reliever must remain available.
  • Confirm correct technique for the specific device and consider a spacer with a metered-dose inhaler to improve deposition.
  • Use the lowest effective dose to maintain control and review periodically.

Monitoring

Monitor asthma or COPD control, inhaler technique, oral candidiasis, and childhood growth on prolonged use.

Counselling the patient

  • Rinse the mouth after inhaling to reduce thrush and hoarseness.
  • Continue daily even when symptom-free, as the protective effect is cumulative.

Evidence & guidelines

Inhaled budesonide is well established as preventer therapy in NICE and GINA asthma guidance and within COPD combination regimens.
