Review question
In people with major depression who haven’t been treated before, are antidepressant drugs any better or worse than other therapies?
Background
Depression is a common mood disorder that affects how you feel, think, and behave. It may be mild or more severe and persistent (major depression). Symptoms include feeling sad, losing interest in things you like to do, having trouble thinking or concentrating, or feeling anxious or restless.
Depression is more than just being sad and may get worse if not treated. There are many treatments for depression including drugs, psychotherapies, and other treatments (e.g., exercise, acupuncture, supplements).
The research
45 studies (randomized controlled trials) that were published up to September 2015.
The studies included outpatients who had a diagnosis of major depressive disorder. Most were women with an average age of about 35 to 45 years.
Studies compared antidepressant drugs (mostly fluoxetine, sertraline, paroxetine, venlafaxine, citalopram, or escitalopram) with other therapies, including psychotherapies (mainly cognitive-behavioural therapy [CBT] or interpersonal psychotherapy), St. John’s wort, acupuncture, exercise, omega-3 fatty acid supplements, or S-adenosyl-L-methionine (SAMe) supplements.
Therapies lasted for at least 6 weeks, and most studies treated people for 12 weeks or less.
What the researchers found
Compared with antidepressant drugs:
- CBT and St. John’s wort reduced depression in about the same number of people at up to 16 weeks of therapy;
- fewer people using St. John’s wort stopped therapy because of an adverse event; and
- about the same number of people having CBT stopped therapy because of an adverse event.
We don’t have enough information about how well other therapies work compared with antidepressant drugs.
Conclusion
In people with major depression who haven’t been treated before, antidepressant drugs, cognitive-behavioural therapy, or St. John’s wort work about equally well.
Antidepressant drugs vs other therapies in people with major depression who haven’t been treated before
| Comparisons | Outcomes | Number of trials and people | Outcome rate with antidepressant drugs | Outcome rate with other therapy | Absolute effect of antidepressant drugs |
| Antidepressant drugs vs CBT | Response rate | 5 trials (660 people) | 44% | 46% | No difference in effect at 8 to 16 weeks* |
|
| Stopped treatment because of adverse events | 3 trials (441 people) | 8% | 3% | No difference in effect* |
| Antidepressant drugs vs St. John’s wort | Response rate | 9 trials (1,517 people) | 52% | 54% | No difference in effect at 6 to 12 weeks* |
|
| Stopped treatment because of adverse events | 9 trials (1,651 people) | 7% | 4% | About 3 more people out of 100 stopped therapy because of an adverse event (from as few as 1 to as many 6 out of 100) |
