Inhaled Corticosteroid Pregnancy: There are limited data in pregnant women. Administration during pregnancy should only be considered if the expected benefit to the mother is greater than any possible risk to the fetus, with the dose titrated to the lowest effective dose; treatment should not be stopped abruptly. A retrospective epidemiological study did not find an increased risk of major congenital malformations after first-trimester exposure compared with other inhaled corticosteroids. Excretion into human breast milk has not been investigated; administration during lactation should only be considered if the expected benefit to the mother is greater than any possible risk to the child.

Fluticasone Propionate

Brand names: Flixotide, Flixonase (nasal)

Fluticasone propionate is an inhaled corticosteroid used in children for the maintenance prophylaxis of asthma; this page covers the inhaled preventer rather than systemic or nasal preparations.

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: Adults and children over 16 years: 100 to 1,000 micrograms twice daily, usually given as two inhalations twice daily. Typical adult starting doses: mild asthma 100 micrograms twice daily; moderate and more severe asthma 250 to 500 micrograms twice daily.
Route: Oral inhalation only (Flixotide Evohaler, pressurised metered-dose inhaler). May be used with a Volumatic spacer device by patients who find it difficult to synchronise aerosol actuation with inspiration. Doses above 1,000 micrograms daily (500 micrograms twice daily) should be given via a spacer device to help reduce side effects in the mouth and throat.
Frequency: Twice daily, taken regularly even when asymptomatic (therapy is prophylactic); the onset of therapeutic effect is within 4 to 7 days
Max: Adults: doses of up to 1,000 micrograms twice daily may be used where additional clinical benefit is expected, and such doses should be initiated only by a specialist in the management of asthma. Because of the risk of systemic effects, doses above 500 micrograms twice daily should be prescribed only for adult patients with severe asthma where additional benefit is demonstrated. CHILDREN: the maximum licensed dose in children is 200 micrograms twice daily.
PAEDIATRIC (this page's primary use) — typical starting doses for children over 4 years of age: 50 to 100 micrograms twice daily. Many children's asthma will be well controlled on the 50 to 100 microgram twice-daily regimen; for those not sufficiently controlled, additional benefit may be obtained by increasing the dose up to 200 micrograms twice daily, which is the maximum licensed paediatric dose. The starting dose should be appropriate to the severity of the disease and should then be titrated down to the lowest dose at which effective control of asthma is maintained. If the Flixotide 50 microgram Evohaler presentation does not offer the exact paediatric dose prescribed, see the data sheets of the alternative Flixotide presentations (Accuhaler, Nebules). The retrieved posology gives doses only for adults and children over 16 years and for children over 4 years of age — no dose is stated for children aged 4 years and under, and no per-kg dosing is given anywhere. Paediatric dosing is safety-critical: verify against a children's formulary. POTENCY EQUIVALENCE: fluticasone propionate is as effective as other inhaled steroids at approximately half the microgram daily dose — 100 micrograms of fluticasone propionate is approximately equivalent to a 200 microgram dose of beclometasone dipropionate (CFC-containing) or budesonide. NOT A RELIEVER: Flixotide Evohaler is not designed to relieve acute symptoms, for which an inhaled short-acting bronchodilator is required; patients should be advised to have rescue medication available. If relief with short-acting bronchodilator treatment becomes less effective, or more inhalations than usual are needed, medical attention must be sought. SYSTEMIC EFFECTS: possible at high doses given for prolonged periods — Cushing's syndrome, Cushingoid features, adrenal suppression, growth retardation in children and adolescents, decreased bone mineral density, and psychological/behavioural effects (psychomotor hyperactivity, sleep disorders, anxiety, depression, aggression — particularly in children); review the dose regularly and reduce to the lowest effective dose. Check inhaler technique regularly. SPECIAL GROUPS: there is no need to adjust the dose in elderly patients or in those with hepatic or renal impairment. US SOURCE NOTE: the openFDA record in this bundle is an over-the-counter fluticasone propionate NASAL SPRAY (adults and children 12 years and over, 2 sprays in each nostril once daily; children 4 to 11 years, 1 spray in each nostril once daily; children under 4 years, do not use) — a different formulation, route and indication. None of its figures have been used for this inhaled-asthma page.

Dose adjustments

Renal

There is no need to adjust the dose in patients with renal impairment (or hepatic impairment), or in the elderly.

Dose auto-extracted from UK Summary of Product Characteristics (SPC) via the eMC; US FDA prescribing information (openFDA / DailyMed) — cross-check; US labelling may differ from UK — not yet clinician-verified. Always confirm against the product SmPC and your local formulary before prescribing.

Contraindications

  • Hypersensitivity to the active substance or to any of the excipients

Side effects

  • Candidiasis of the mouth and throat (very common) and hoarseness/dysphonia (common) — rinsing the mouth with water after use may help; oesophageal candidiasis (rare)
  • Pneumonia in COPD patients (common) and contusions (common)
  • Cutaneous hypersensitivity reactions (uncommon); angioedema (mainly facial and oropharyngeal), respiratory symptoms (dyspnoea and/or bronchospasm) and anaphylactic reactions (very rare)
  • Cushing's syndrome, Cushingoid features, adrenal suppression, growth retardation in children and adolescents, decreased bone mineral density, cataract, glaucoma (very rare); hyperglycaemia (very rare)
  • Anxiety, sleep disorders and behavioural changes including hyperactivity and irritability, predominantly in children (very rare); depression and aggression, predominantly in children (not known); paradoxical bronchospasm (very rare) — treat immediately with a fast-acting inhaled bronchodilator and discontinue

Clinical monograph

How it works

A potent glucocorticoid that, after delivery to the airways, binds glucocorticoid receptors to suppress airway inflammation, reduce mucosal oedema and decrease bronchial hyper-responsiveness.

Prescribing in practice

  • Inhaled corticosteroids can cause growth retardation in children, so use the lowest effective dose, monitor height and review the need for treatment regularly.
  • Use an age-appropriate spacer (with facemask in young children) and correct inhaler technique to maximise lung deposition and reduce oropharyngeal effects.
  • It is a preventer, not a reliever, and must be taken regularly even when the child is well.

Monitoring

Monitor the child's height and growth, asthma control and inhaler technique at routine reviews.

Counselling the patient

  • Rinse the mouth and spit out after each dose to reduce the risk of oral thrush and hoarseness.
  • Use every day as a preventer, not for sudden breathlessness.
  • Always use the prescribed spacer device and bring it to reviews so technique can be checked.

Evidence & guidelines

Inhaled corticosteroids are first-line preventer therapy in paediatric asthma per NICE/BTS-SIGN guidance.

Reference: BTS/SIGN Asthma Guidelines 2019; MHRA Drug Safety Update 2018 (fluticasone/ritonavir); NICE NG80; Drug verified in RxNorm (NLM); confirm dosing against the manufacturer SPC (eMC). Verify against your local formulary and current prescribing references before prescribing. The structured dose values shown have been reviewed by a clinician. Monograph status: clinician-reviewed (2026-07-04).
