Family doctors are leaving patients in the dark about the side effects of antidepressants, sedatives and other psychiatric treatments, experts have warned.
Four in every five patients with mental health problems were not told the potential side effects of their medications, according to the charity Mind.
The organisation's annual survey, which asked 12,000 people about their experiences, found 53 per cent of patients did not receive enough information about the purpose of treatments they were prescribed.
Only 21 per cent of patients were given an explanation about the side effects their medication might have.

And just last month Public Health England also accepted there was a risk, pointing out in a major report that 7million people in England are now on antidepressants, with 1million of them having taken the drugs for more than three years.
Sophie Corlett, Mind's director of external relations, said: 'Our research revealed a worrying number of us are receiving life changing treatment without fully understanding what it involves. This has got to change.
'GPs do an extremely difficult job often under inadequate time restraints.
'But with GPs often the first port of call for mental health support, it's crucial they have the opportunity to get the training they need to support patients to have the information to make decisions about their treatment.
'Medication can be effective in managing symptoms of mental health problems, but not for everyone.
'It is critical people are told about potential adverse side effects, such as suicidal thoughts and self-harm, so they can make informed choices.'
People in Britain use more antidepressants than almost every other country in the Western world, which experts believe is partly due to lack of awareness of withdrawal problems.
