First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests whether a supervised, gradual reduction of antidepressants can safely lower unnecessary long-term use in adults with mild depression or anxiety. Researchers will enroll 325 people from a health center in Spain who have taken antidepressants in the past year. The goal is to see if deprescribing improves quality of life without causing a return of symptoms.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Deprescription of antidepressants (fluoxetine, citalopram, sertraline, paroxetine, escitalopram)
- What this could lead to
- If successful, this could show that many people can safely reduce or stop antidepressants without worsening anxiety or depression, leading to better quality of life and fewer side effects.
- What could go wrong
- This is an early-phase trial with only 325 participants, so results may not apply to everyone. Some people might experience withdrawal symptoms or a return of depression or anxiety during dose reduction.
