The study included 2,372 adult primary care patients prescribed regular ICS for asthma. Adherence to treatment was poor in 38.2 per cent of these patients.
Poor adherence was found to be high in the 10 per cent of patients who experienced bothersome symptoms that they attributed to ICS use. These included cough, hoarse voice, sore mouth, weight gain, bruising, dental decay and oral thrush.
Adherence was also low in the 21 per cent who reported having concerns about the long-term effects of ICS and lowest in the 18 per cent who doubted their need for ICS treatment.
Professor David Price, professor of respiratory medicine at Aberdeen University and researcher on the study, said patient concerns should be heeded.
'We could achieve better results in some patients by prescribing a lower-dose steroid with an add-on therapy than a high-dose steroid that they are reluctant to take,' he said.
The results were presented at a conference on respiratory disease in Norway this week.
