Almost half of people on antidepressants could quit

The study is the latest in a seven-year research programme named REDUCE

Nearly half of long-term antidepressant users can stop using the medication with GP support and access to internet or telephone helplines alone, a study has revealed.

Scientists found that more than 40% of people involved in the research who were well and not at risk of relapse managed to come off the drugs with advice from their doctors.

The study, published in the journal JAMA Network Open, was led by the universities of Southampton, Liverpool and Hull York Medical School. 

The researchers discovered patients who could access online support and psychologists by phone had lower rates of depression, fewer withdrawal symptoms, and reported better mental wellbeing.

More than 10% of adults in the UK are taking antidepressants for depression, with more than half using them for longer than two years, according to NHS figures.

Lead authot Professor Tony Kendrick, from the University of Southampton, said the findings were significant as they showed high numbers of patients withdrawing from the drugs without the need for costly intense therapy sessions.

‘This approach could eliminate the risk of serious side effects for patients using antidepressants for long periods who have concerns about withdrawal,’ he said. 

‘Offering patients internet and psychologist telephone support is also cost-effective for the NHS.

‘Our findings show that support not only improves patient outcomes, but also tends to reduce the burden on primary healthcare while people taper off antidepressants.’

A total of 330 adults who had been taking the medication for more than a year for a first episode of depression, or more than two years for a recurrence of the illness, were enrolled into the study.

Co-author Una Macleod, professor of primary care medicine at Hull York Medical School, said: ‘Many patients are taking antidepressants for depression for longer than two years, when they probably no longer need them.

‘The evidence in our study is clear and suggests the UK should establish a national helpline, by phone and online, to help people intending to come off the medication.’

The new study is the latest in a seven-year research programme, named Reduce, led by the universities to investigate the long-term effects of withdrawing from antidepressants.

Professor of general practice Mark Gabbay, a co-author from the University of Liverpool, said the research showed that many patients do not need intense face-to-face therapy sessions while withdrawing.

‘This is the first study to demonstrate that stopping inappropriate long-term antidepressant treatment is possible at scale without psychological therapy,’ he said. 

‘Antidepressants are recommended only for up to two years in most cases, and people are running the risk of increasing side effects as they get older.

‘From our findings, we are calling for active family practitioner reviews for antidepressant discontinuation to be promoted.’
