Most people stop antidepressants too early or stay on them too long, creating a dangerous gap between what science shows works and what actually happens in doctors’ offices.
Story Overview’
- Clinical guidelines recommend staying on antidepressants at least 6-12 months after feeling better
- Half of new users quit within 6 months, while others remain on medications for years without review
- Large Danish study of 89,000 adults suggests 10-12 months may be optimal to prevent relapse
- Duration recommendations vary dramatically based on depression history and individual risk factors
The Six Month Problem That Nobody Talks About
The moment you start feeling better on antidepressants marks the beginning of the most critical phase of treatment, not the end. Clinical guidelines consistently recommend continuing medication for at least six months after symptoms disappear, yet real-world data reveals a troubling pattern. In a massive study of Australian veterans, exactly half stopped their antidepressants within six months, and 61% quit within a year.
This premature discontinuation creates a revolving door of relapse that could be prevented. The World Health Organization updated their 2023 guidelines to emphasize at least six months of continuation after remission, though they grade the certainty of this evidence as very low. The recommendation exists because stopping too early dramatically increases the risk of sliding back into depression.
Why Ten to Twelve Months May Be the New Standard
A groundbreaking Danish study tracking 89,442 adults between 2006 and 2015 revealed something that challenges existing guidelines. Researchers found that people who stayed on antidepressants for 10-12 months had significantly lower relapse rates than those who stopped earlier. One in three patients who discontinued their medication relapsed within a year, regardless of how good they felt when stopping.
This data suggests the traditional six-month minimum may be inadequate for many patients. The study authors concluded that a minimum of 10-12 months appears preferable when relapse prevention is a primary concern. This finding aligns with the reality that most antidepressants take 6-12 weeks to reach full effectiveness, meaning the continuation phase after feeling better becomes even more critical than previously understood.

The Three Episode Rule That Changes Everything
Depression follows a ruthless mathematical progression that fundamentally alters treatment duration recommendations. After one episode, approximately 50% of people will experience another. After two episodes, that risk jumps to 70%. After three episodes, the recurrence rate climbs to a staggering 90% if left untreated.
These statistics explain why clinical guidelines dramatically shift toward long-term maintenance therapy for people with recurrent depression. Multiple professional organizations now recommend years of continued treatment, sometimes indefinitely, for patients who have experienced three or more serious depressive episodes.

The Withdrawal Syndrome That Complicates Everything
The decision about when to stop antidepressants becomes exponentially more complex because withdrawal symptoms can perfectly mimic depression relapse. Clinical reviews emphasize that gradual dose reduction over weeks or months is crucial, with some experts recommending switching to fluoxetine as a bridge medication for patients experiencing severe withdrawal symptoms due to its longer half-life.
This withdrawal complexity creates a clinical dilemma that extends far beyond simple duration recommendations. Many patients who attempt to stop their medications interpret withdrawal symptoms as evidence they still need the drugs, leading to indefinite continuation. Others push through withdrawal symptoms and mistake them for returning depression, creating unnecessary fear about their mental health stability.
