Stepping down asthma treatment guidelines The potential for inhaled corticosteroids (ICS) to cause dose-related side-effects has led to asthma management guidelines recommending a dose reduction once asthma control is achieved. By adopting a stepwise approach to the use of ICS, a reduction in the dose can be achieved without compromising asthma control in patients with mild 1,2 moderate or severe disease. 3 A suitable reduction in dose in appropriate patients will make little difference to their disease control but will significantly reduce the potential for side-effects. The following patients should be considered for a reduction of ICS dose: Include patients: with a confirmed diagnosis of asthma and who have been free of asthma symptoms for 3 months or more. Exclude patients: with ongoing symptoms, or needing to use Short Acting Beta Agonist (SABA) e.g. salbutamol, terbutaline three times a week or more [N.B. some patients are still incorrectly directed to use SABAs on a regular basis e.g. QDS not PRN] who have had an exacerbation, oral corticosteroid course, or visit to GP or hospital because of worsening asthma, in preceding three months. with serious illness, substance misuse, or pregnancy. who cannot use a peak flow meter. Method: Check with the patient that their asthma is well controlled. Explain that reducing the dose of ICS reduces the potential for side-effects and ask if they agree to try stepping-down their treatment. Record objective measurements of their current lung function e.g. Peak flow or spirometry, and check inhaler technique by asking the patient to demonstrate. Check the patient s adherence to the prescription for both ICS and SABA; look at the prescription history and calculate usage to see how it matches with expected usage. This will enable you make a better judgement of how or whether to reduce the dose. Check the patient s understanding of the need for daily preventative therapy. Reduce the dose of inhaled corticosteroids slowly (See Flow Charts below). The usual protocol is to decrease the ICS dose by 25% to 50% per 3-month visit. Some children with milder asthma and a clear seasonal pattern to their symptoms may tolerate a more rapid dose reduction during their 'good' season. N.B. A change from a middle range fluticasone preparation e.g.seretide 125 or Flutiform 125/5, to a low range fluticasone preparation e.g. Flutiform 50/5, represents a 60% reduction in ICS dose and additional care is required. If the patient is using a combination inhaler, you may need to consider prescribing separate inhalers for this process or switching to a different device with more flexibility e.g. Fostair or Symbicort. Ideally the dose of LABA (long-acting beta-agonist) should remain constant during this process, so only one drug element is reduced at a time, but this is not always possible when stepping down using combination inhalers. If you are changing to a different ICS, use Appendix 1 to work out the equivalent dose of the new ICS. Explain to the patient the potential for worsening symptoms and the increased risk of an exacerbation. Make sure the patient has an up-to-date written personalised asthma action plan. o A typical asthma action plan should include: o When to increase treatment (as defined by symptoms or peak expiratory flow rate). How to change treatment in case of deterioration and when to go back to maintenance medication. o When to seek medical help. o Agree a review date for 3 months time.
