Intranasal corticosteroid users in The Netherlands: A drug utilization study.

Background: To improve (patient-tailored) instructions for intranasal corticosteroid (INC) administration, we need to gain insight into specific characteristics of INC users and comedication use.

Objective: We examined INC prescriptions obtained from the Dutch InterAction Database to gain insight into the prevalence and incidence rates, INC use in previous years, and comedication.

Methods: We retrospectively examined INC prescriptions written between January 1, 2015, and December 31, 2019.
