Antidepressants may offer little extra benefit once a person has taken them for more than a year, according to a new clinical overview published in the Australian Journal of General Practice. The review, led by researchers from the University of Adelaide and the University of Queensland, also highlights that continuing these medications long term is linked to higher risks of side effects, including weight gain, sexual dysfunction, and bone fractures. The authors call for routine treatment reviews at least every six months to reassess whether continued use is still appropriate.

Key takeaways

  • Antidepressant benefits beyond 12 months of continuous use are limited and not well supported by evidence.
  • Long-term use increases the risk of several adverse health outcomes, such as weight gain, sexual problems, and fractures.
  • The review urges doctors to review antidepressant treatment at least every six months, especially in patients without clear ongoing benefits.
  • Depression relapse prevention is often used to justify long-term use, but the evidence for this is weaker than previously thought.
  • Individualized treatment plans and gradual dose reduction may be safer than indefinite continuation.

What the review found about long-term antidepressants

The clinical overview examined existing evidence on the efficacy and risks of antidepressant therapy beyond the first year. According to the report, most clinical trials on antidepressants focus on short-term use of 8 to 12 weeks. Few high-quality studies have followed patients for longer than one year, making it difficult to support indefinite prescribing. The researchers concluded that after 12 months, the preventive effect against relapse diminishes and does not clearly outweigh the accumulating side effects.

In a statement to Medical Xpress, the authors noted that many patients continue taking antidepressants for years without a formal review. They suggest that doctors and patients should have frank discussions about whether the medication is still doing its job, and if the risks are starting to exceed the benefits.

Risks of long-term antidepressant use

The review highlights several health issues that emerge or worsen with extended antidepressant use. These include significant weight gain, sexual dysfunction such as reduced libido and difficulty achieving orgasm, and an elevated risk of fractures, especially in older adults. Other potential problems cited were gastrointestinal bleeding and a possible increase in mortality among elderly patients. The authors stress that these risks should not be overlooked simply because the treatment has continued for years without incident.

Why six-month reviews are needed

The researchers propose that general practitioners schedule a formal reassessment of antidepressant therapy every six months. This review would involve evaluating the patient’s current depressive symptoms, checking for side effects, and discussing the possibility of tapering or discontinuing the medication. The goal is to avoid unnecessary long-term exposure while still providing adequate support for those who truly benefit. The authors emphasize that each patient’s situation is different, and decisions should be made collaboratively between doctor and patient.

Implications for patients and doctors

For patients who have been taking antidepressants for more than a year, this review is a reminder that ongoing medication may not always be the best option. The report suggests that non-drug treatments, such as cognitive behavioral therapy, exercise, and social support, can be effective alternatives or additions. Doctors, in turn, are encouraged to educate themselves on tapering protocols to minimize withdrawal symptoms. The overall message is that longer does not always mean better when it comes to antidepressant use.

Frequently Asked Questions

Should I stop taking my antidepressants immediately?

No. The review does not recommend sudden discontinuation, which can cause severe withdrawal symptoms. Instead, patients should consult their doctor to discuss a gradual tapering plan if a medication review indicates that continued use may no longer be beneficial.

Does this apply to all antidepressants?

The review looked broadly at commonly prescribed antidepressants, including SSRIs and SNRIs. While individual medications have different risk profiles, the overall finding of limited long-term benefit and increased side effects was consistent across the class. Your doctor can provide guidance specific to your medication.

What alternatives to long-term antidepressants exist?

Evidence-based alternatives include psychotherapy (especially cognitive behavioral therapy), regular physical activity, mindfulness, and lifestyle changes. For some people, periodic short-term antidepressant use combined with these therapies may be more effective than indefinite daily dosing.
