Why Are So Many Australians Taking Antidepressants?

Australia has one of the highest antidepressant prescribing rates in the world, with over 3.5 million Australians dispensed antidepressant medication in 2021-22. One in seven Australians take antidepressants, yet the evidence suggests they’re often over-prescribed. So, what’s driving this trend?

The Origins of Antidepressant Prescription
==========================================

The 1990s saw the emergence of selective serotonin reuptake inhibitors (SSRIs), such as Prozac, Zoloft, and Lexapro. Pharmaceutical companies heavily promoted these drugs, exaggerating their benefits and using “key opinion leaders” (high-status clinicians) to tout their effectiveness.

GPs prescribed these drugs at an unprecedented rate, and the antidepressant market boomed. Manufacturers earned billions, and prescription rates continue to rise, with annual growth rates of 4.5%.

Why Are Antidepressants Prescribed?
———————————–

Despite clinical guidelines recommending antidepressants for severe depression and anxiety, they’re often prescribed as first-line treatment for mild depression. Many patients receive prescriptions without a proper diagnosis, simply to alleviate symptoms like distress, sleep disturbances, or stress.

GPs may be swayed by the convenience and apparent effectiveness of antidepressants, while some patients may request prescriptions or try to “self-medicate” after an acquaintance’s positive experience. Others may be seeking emotional support or a means to cope with adversity.

But antidepressants don’t work for everyone. Some individuals experience side effects, including impaired sexual function, weight gain, nausea, and insomnia. Up to half of users may struggle with long-term sexual dysfunction after stopping antidepressants.

How Long Do People Take Antidepressants?
—————————————

Antidepressants are often consumed for years, with long-term use driving prescription rates. The majority of users who try to stop taking antidepressants experience withdrawal symptoms, such as “brain zaps,” dizziness, and nausea.

The withdrawal process is crucial, but many doctors fail to guide patients through this phase. The Australian-based Maudsley Deprescribing Guidelines provide valuable guidance on tapering off antidepressants.

We Need to Rethink Mental Distress
———————————–

Overprescription is symptomatic of society’s neglect of mental health’s social determinants. It’s essential to acknowledge that depression and anxiety can stem from poverty, unemployment, and social inequality.

Moreover, diagnosing individuals with mental health conditions without considering the broader social context can perpetuate stigma and medicalization. Meaningful support for mental distress lies in addressing inequality, social justice, and community attitudes toward mental health.

In conclusion, Australia’s high antidepressant prescription rate reflects a complex issue influenced by factors like pharmaceutical promotion, patient demand, and GP workload pressures.

To reverse this trend, GPs need better training, support, and evidence-based guidance. Most importantly, society must recognize that mental distress is often rooted in social determinants and address inequality to provide comprehensive support.
