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 and the need for a balanced approach to mental health treatment.
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 paint a worrying picture: a steady increase in long-term use across all age groups, with the most dramatic rise seen in individuals aged 10-24, where rates have more than doubled.
But here's where it gets controversial...
Lead author Dr. Lasantha Ranwala highlights a critical shift in antidepressant usage, raising concerns about potential overprescribing and a lack of adherence to clinical guidelines. These guidelines recommend a careful review of medication use after 6-12 months, but the study reveals that 45% of young people on antidepressants continue their treatment for over a year, with many still using them after two years.
"Not only are more people taking antidepressants, but they're staying on them for longer periods," Dr. Ranwala emphasizes. This prolonged use, especially among younger age groups, is concerning as clinical guidelines generally recommend psychological therapies as the first line of treatment.
Across the population, long-term antidepressant use increased from 66 to nearly 85 users per 1000 people between 2014 and 2022, with women consistently recording higher use than men.
Dr. Ranwala warns, "While antidepressants play a crucial role in managing moderate to severe depression, prolonged use can lead to increased side effects and make withdrawal more challenging. Withdrawal symptoms are often misinterpreted, leading to extended treatment and further complications."
And this is the part most people miss...
The study also found a lack of progress in efforts to wean people off antidepressants. The proportion of long-term users put on a lower dose remained constant over the decade, suggesting that deprescribing strategies are not routinely implemented in clinical practice.
Co-author Professor Libby Roughead, Director of the Quality Use of Medicines and Pharmacy Research Centre, states, "This lack of movement is concerning, especially given the increase in long-term use, particularly among young people. It's an area that requires immediate attention."
Researchers attribute this trend to various factors, including a spike in mental health issues among young people, rising psychological distress rates, the impact of the COVID-19 pandemic, and difficulties accessing psychological therapies.
With mental health demands at an all-time high, the authors advocate for a more balanced approach, ensuring antidepressants are used appropriately and patients receive adequate support to reduce or discontinue treatment when clinically appropriate.
"Australia needs a stronger framework for safely tapering antidepressants and better access to psychological care," Professor Roughead emphasizes.
Associate Professor Andrew Andrade, another co-author, suggests that emerging technologies like predictive analytics and clinical decision-support tools could help clinicians identify when deprescribing is appropriate.
"Clinicians require stronger support systems to safely deprescribe antidepressants. Smart technologies can identify suitable candidates for tapering, coordinate access to non-pharmacological treatments, and provide clear guidance throughout the dose-reduction process," Assoc Prof Andrade concludes.
This study, titled 'Increasing Prevalence of Long-Term Antidepressant Use in Australia,' is a call to action for a more holistic and responsible approach to mental health treatment.
