One in four Brits on anti-depressants in England have been taking them for more than five years.
Around eight million NHS patients are currently prescribed medication such as sertraline and citalopram, figures have shown, two million of which have been on the drugs long-term.
The drugs are used to help people with depression, anxiety and Obsessive Compulsive Disorder (OCD), with the number of prescriptions given out up by a million in just a year.
