Fluticasone with salmeterol
Brand names: Seretide, AirFluSal, Sereflo, Sirdupla
This inhaler combines the inhaled corticosteroid fluticasone propionate with the long-acting beta2 agonist salmeterol (e.g. Seretide), used as maintenance therapy for asthma and COPD.
Adult dose
Dose adjustments
SPC 4.2 verbatim: 'There is no need to adjust the dose in elderly patients or in those with renal impairment.' No dose adjustment is required in renal impairment.
SPC 4.2 verbatim: 'There are no data available on the use of AirFluSal Forspiro in patients with hepatic impairment.' No numeric hepatic dose adjustment is given.

Contraindications
- Hypersensitivity to the active substances or to any of the excipients listed in section 6.1 - the only contraindication in SPC 4.3
- Not a contraindication but a licensed-age restriction for this product (SPC 4.2, 4.4, verbatim): 'AirFluSal Forspiro is not recommended for use in either children aged 12 years and younger or in adolescents aged 13 to 17 years. The safety and efficacy of AirFluSal Forspiro in children and adolescents aged less than 18 years of age has not been established. No data are available.' This is specific to the AirFluSal Forspiro 50/500 product sourced here, not a statement about every salmeterol/fluticasone combination - verify any paediatric use against a children's formulary
- Not a contraindication but a severity restriction (SPC 4.4): AirFluSal Forspiro is for use in patients with severe asthma only; it should not be used in patients with mild or mild to moderate asthma, and should not be used as initial maintenance therapy in patients with moderate persistent asthma
- Not a contraindication but a use restriction (SPC 4.4): it should not be used to treat acute asthma symptoms, for which a fast and short-acting bronchodilator is required
- Not a contraindication but an initiation bar (SPC 4.4): 'Patients should not be initiated on AirFluSal Forspiro during an exacerbation, or if they have significantly worsening or acutely deteriorating asthma.'
- SPC 4.5 (interactions with other medicinal products) was not retrieved in this bundle - review the SPC directly before assuming there are no interaction-based restrictions
Side effects
- SPC 4.8: 'As AirFluSal Forspiro contains salmeterol and fluticasone propionate, the type and severity of adverse reactions associated with each of the compounds may be expected. There is no incidence of additional adverse events following concurrent administration of the two compounds.'
- Very common: headache; nasopharyngitis
- Common: candidiasis of the mouth and throat; pneumonia (in COPD patients); bronchitis; hypokalaemia; throat irritation; hoarseness/dysphonia; sinusitis; contusions; muscle cramps; arthralgia; myalgia; traumatic fractures
- Uncommon: cutaneous hypersensitivity reactions; respiratory symptoms (dyspnoea); hyperglycaemia; anxiety; sleep disorders; tremor; cataract; palpitations; tachycardia; atrial fibrillation; angina pectoris
- Rare: oesophageal candidiasis; angioedema (mainly facial and oropharyngeal oedema); respiratory symptoms (bronchospasm); anaphylactic reactions including anaphylactic shock; Cushing's syndrome, Cushingoid features, adrenal suppression, growth retardation in children and adolescents, decreased bone mineral density; behavioural changes including psychomotor hyperactivity and irritability (predominantly in children); glaucoma; cardiac arrhythmias including supraventricular tachycardia and extrasystoles; paradoxical bronchospasm
- Not known: depression, aggression (predominantly in children); vision, blurred
- SPC 4.8: 'The pharmacological side effects of beta-2 agonist treatment, such as tremor, palpitations and headache, have been reported, but tend to be transient and reduce with regular therapy.'
- SPC 4.8 note on the table: headache and nasopharyngitis were reported commonly/very commonly in placebo, and pneumonia, bronchitis, hypokalaemia, sinusitis, contusions and traumatic fractures were reported over 3 years in a COPD study
- Section 4.8 was truncated at the source-fetch limit - the description of selected adverse reactions is incomplete here
Monitoring
- SPC 4.2: patients should be regularly reassessed by a doctor so that the strength of the salmeterol/fluticasone propionate inhaler they are receiving remains optimal and is only changed on medical advice; in asthma the dose should always be titrated to the lowest dose at which effective control of symptoms is maintained
- SPC 4.2: correct use of the Forspiro inhaler should be demonstrated to the patient and checked regularly
- SPC 4.2, 4.4: rinse the mouth with water and spit it out after each dose - this may help prevent oral candidiasis and hoarseness
- SPC 4.4: increased requirements for reliever medication (short-acting bronchodilators), or a decreased response to reliever medication, indicate deterioration of asthma control and the patient should be reviewed by a physician; sudden and progressive deterioration in control of asthma is potentially life threatening and requires urgent medical assessment
- SPC 4.4: patients should continue treatment but seek medical advice if asthma symptoms remain uncontrolled or worsen after initiation
- SPC 4.4: regular review of patients as treatment is stepped down; once asthma symptoms are controlled, consideration may be given to gradually reducing the dose of inhaled corticosteroid, and the lowest effective dose should be used
- SPC 4.4: in COPD, patients should be instructed to seek medical attention if symptoms deteriorate, since exacerbations typically require systemic corticosteroids
- SPC 4.8 (rare, class effects to watch for on long-term high-dose inhaled corticosteroid): adrenal suppression, decreased bone mineral density, cataract and glaucoma, and growth retardation in children and adolescents
Clinical monograph
How it works
Fluticasone propionate provides anti-inflammatory corticosteroid action, while salmeterol gives prolonged bronchodilation by stimulating beta2 adrenoceptors; salmeterol has a slow onset and is unsuitable for acute relief.
Prescribing in practice
- Salmeterol has a slow onset and must never be used to treat an acute asthma attack, and the long-acting beta2 agonist must always be paired with the inhaled corticosteroid.
- Inhaled corticosteroid use raises pneumonia risk in COPD and can cause oral candidiasis and dysphonia.
- Beta2 agonist effects include tremor, palpitations and hypokalaemia, warranting caution in cardiovascular disease.
Monitoring
Review symptom control and inhaler technique, monitor for pneumonia in COPD, oral thrush, and growth in children on long-term therapy.
Counselling the patient
- Use regularly as a preventer; it will not relieve sudden breathlessness.
- Rinse the mouth after each dose to reduce thrush and hoarseness.
- Always carry a fast-acting reliever and seek help if symptoms worsen.
