High adherence to subcutaneous immunotherapy in a real-life study from a large tertiary medical center.

Background: Studies on real-life adherence to subcutaneous allergen immunotherapy (SCIT) for respiratory allergy are scarce. The aim of this study was to evaluate adherence to SCIT.

Methods: The patients prescribed SCIT for allergic rhinitis and/or asthma in 2009-2011 were contacted in 2014 and asked whether they completed at least the 3 years of SCIT and/or whether they suspended the treatment for at least 2 months.
