One in six people who come off antidepressants will experience withdrawal symptoms as a direct result, according to the most comprehensive study to date into the problem. Researchers estimate that the effects of discontinuing the drugs will be severe for one in 45 patients, which can include feelings of dread and anxiety, insomnia, loss of libido and sexual function, brain zaps, dizziness, and suicidal thoughts. The findings, published in the journal Lancet Psychiatry, are based on a meta-analysis of 76 existing papers comparing outcomes among 21,000 patients on a range of different antidepressants or a placebo - an inert "dummy" drug.
