Asthma action plan (AAP) is an essential component of asthma education and self-management. AAPs provide patients with instructions on how to recognise loss of asthma control and the appropriate treatment steps. The use of AAP improves asthma-related quality of life and reduces the risk of asthma exacerbation. Despite its benefits, utilisation of AAP is disappointingly low both locally and worldwide. This review highlights the importance of AAP as part of an asthma care plan and provides practical information on the prescription of AAPs. We conclude by identifying possible barriers to AAP implementation and how these may be overcome.
