Drug survival and risk factors for ADHD medication discontinuation in adults: A Danish Nationwide Registry-based cohort study.

The 5-year overall drug survival was longer in women compared to men. Women with ADHD; adults aged 31-50; and patients with comorbid eating disorder; intellectual disability; sleep disorder and medication switching were individually associated with continuation of ADHD medication. Various factors were associated with medication discontinuation. Discontinuation should be acknowledged as a common phenomenon in patients with ADHD and calls for increased attention from the treatment responsible prescriber or team. Moreover, our findings suggest that timely, frequent medication switching, or temporary regimens may indeed represent optimal management strategies for a significant proportion of the ADHD population.
