A concerning trend has emerged in Australia, with a significant rise in long-term antidepressant use, particularly among young people. This revelation has sparked a much-needed conversation about the potential overprescription of these medications.
The study, conducted by researchers at the University of South Australia, analyzed data from over 300,000 antidepressant users between 2014 and 2023. The results are eye-opening: a 45% increase in young people aged 10-24 staying on antidepressants for over a year, with many continuing for two years or more.
But here's where it gets controversial... The study's lead author, Dr. Lasantha Ranwala, highlights a critical shift in antidepressant usage. While these medications are beneficial for managing moderate to severe depression, the prolonged use raises concerns about side effects and the difficulty of withdrawal.
Dr. Ranwala emphasizes, "Once people start, they're staying on them for longer." This is especially concerning for younger individuals, as clinical guidelines typically recommend psychological therapies as the first line of treatment.
The data shows a steady increase in long-term antidepressant use across all age groups, with the most dramatic rise among young Australians. Between 2014 and 2022, the rate increased from 66 to nearly 85 users per 1000 people, with women consistently recording higher usage than men.
And this is the part most people miss... The researchers also found a lack of progress in weaning people off antidepressants. The proportion of long-term users put on lower doses remained constant over the decade, at around 17.8%. Professor Libby Roughead, co-author and Director of the Quality Use of Medicines and Pharmacy Research Centre, suggests this indicates a lack of routine implementation of deprescribing strategies in clinical practice.
Professor Roughead states, "Given the increase in long-term use, especially among young people, this is an area that requires urgent attention."
So, what's driving this trend? The researchers point to a spike in mental health issues among young people, rising rates of psychological distress, the impact of the COVID-19 pandemic, and difficulties accessing psychological therapies.
The authors argue for a more balanced approach, ensuring antidepressants are used appropriately and patients receive adequate support to reduce or discontinue treatment when necessary.
A call for action: Professor Roughead emphasizes the need for a stronger framework to safely taper antidepressants and better access to psychological care. Associate Professor Andrew Andrade suggests emerging technologies like predictive analytics and clinical decision-support tools could help identify when deprescribing is appropriate, providing a clear, step-by-step process for clinicians and patients.
This study, "Increasing Prevalence of Long-Term Antidepressant Use in Australia," published in Pharmacoepidemiology and Drug Safety, highlights a critical issue in mental health management. It prompts us to reflect on our approach to antidepressant use and the importance of balanced, patient-centered care.
