Information from NICE’s Covid-19 rapid guideline: severe asthma

Information from NICE’s Covid-19 rapid guidelines for severe asthma. This information was first collated and published on our sister title Pulse.


In rapid guidance produced by NICE in light of Covid-19, it says –

Be aware that severe asthma is defined by the European Respiratory Society and American Thoracic Society as asthma that requires treatment with high-dose inhaled corticosteroids (see inhaled corticosteroid doses for NICE’s asthma guideline) plus a second controller (and/or systemic corticosteroids) to prevent it from becoming ‘uncontrolled’, or which remains ‘uncontrolled’ despite this therapy.
