The use of antidepressants has surged across the rich world over the past decade, according to the Organisation for Economic Co-operation and Development, raising concerns among doctors that pills are being overprescribed.

Figures show that doctors in some countries are writing prescriptions for more than one in 10 adults, with Iceland, Australia, Canada and the other European Nordic countries leading the way.

Separate data from the US shows that more than 10% of American adults use the medication. In China, the antidepressant market has grown by about 20% for each of the past three years, albeit from a lower base.

Global rates of depression have not risen to the same extent, even though more people are being diagnosed in some countries.

In its Health at a Glance report to be released on Thursday , the OECD said that rising consumption levels could be explained by the use of antidepressants in milder cases. "These extensions have raised concerns about appropriateness," it said.

It added that the financial crisis may have been a factor in more recent increases in usage, noting that in Spain and Portugal, for example, antidepressant prescriptions have jumped by more than 20% over the past five years.

Most psychiatrists agree that antidepressants work for people with severe illness but are not supposed to be the first resort for those with mild depression. Counselling and talking therapies, such as cognitive behaviour therapy (CBT), are recognised as just as effective over the long term. But counselling is in short supply in many countries.

"We know that antidepressants work for moderate to severe depression," said Dr Mark van Ommeren, of the World Health Organisation's department of mental health and substance abuse. "The explosion of antidepressants you see in most countries reflects the fact that lots of people with moderate to severe depression are getting treatment – that's a good thing.

"But the negative thing is that a lot of people are getting antidepressants who shouldn't be getting them. Doctors and healthcare providers should be able to recognise depression correctly so that those who need antidepressants get them and those with only mild cases do not get prescribed."

The modern antidepressants known as SSRIs (selective serotonin reuptake inhibitors), such as Prozac, took off in the 1990s and gained almost cult status with the publication of Elizabeth Wurtzel's book Prozac Nation in 1994.

Doctors were happier to prescribe them because they did not have the addictive properties or side-effects of pills such as benzodiazepines. But the bubble seemed to burst within a few years, with stories of some, particularly younger, people attempting suicide while on the drugs. Some companies paid large sums to settle court cases in the US and UK doctors were warned in 2003 not to prescribe them to the under-18s.

But the issues around the various medications do not seem to have affected the long-term upward trend. The OECD figures show Iceland to have the highest prescribing rate, at 105.8 doses a day for every 1,000 inhabitants in 2011, up from 70.9 in 2000 and 14.9 in 1989, when it first submitted figures.

Three countries have figures in the 80s in 2011 – Australia, up from 45.4 in 2000 to 88.9 in 2011; Canada, up from 75 in 2007, when it first submitted figures, to 85.9 and Denmark, up from 34.8 to 85.2. The lowest rate in 2011 was in Chile, where 12.8 daily doses were prescribed for every 1,000 inhabitants. In the UK, rates have roughly doubled over the past decade to 70.7 for every 1,000 people.

Most experts say that antidepressants are over-prescribed for some people but underused in others. "Antidepressants are widely oversubscribed to get rid of unhappiness," said Professor Tim Cantopher, consultant psychiatrist with the Priory Group in the UK. "They were not designed for that. Unhappiness is part of the human condition. But real clinical depression does respond to antidepressants. And not to prescribe in these cases is to sentence an individual to a far longer illness than he or she need suffer."

Harvey Whiteford, Kratzmann professor of psychiatry and population health at the University of Queensland, Australia, said depression was very common and was the second leading cause of health-related disability. But in most OECD countries, he said, only about 50-60% of those suffering from depression got treatment, although the rates were increasing.

The sort of treatment people needed varied according to their illness, he said. "There is good evidence that only major depression is likely to respond to antidepressants and other forms of depression much less so."

Primary care physicians tend to prescribe drugs rather than CBT, although some countries, including the UK and Australia, have initiatives intended to increase the availability of counselling.

Whiteford said: "My view is that antidepressants are often prescribed for the increasing numbers of people now coming to treatment for depression (including mild to moderate forms of depression) where CBT would be the better treatment. Thus, the prescribing rates are going up and some of this prescribing would be for types of depression better treated non-pharmacologically."

A Better Access scheme, which subsidised CBT for common mental disorders, increased treatment rates in Australia from 37% in 2006-07 to 46% in 2009-10, Whiteford said. "To get access to psychologists for CBT under the scheme required referral from a GP who made the diagnosis and ruled out medical causes for the anxiety and depression. We hoped this would decrease the prescribing rates of medication with referral to a psychologist being substituted as first-line treatment for mild to moderate disorders. However, what seems to have happened is that most GPs prescribed and referred for CBT."

Professor Tim Kendall, director of the National Collaborating Centre for Mental Health in the UK, said he doubted whether the rise of antidepressant prescription was a result of better recognition of depression in so many countries. "It's much more likely a testament to the effective marketing by the pharmaceutical industry," he said. "I also wonder if, in better-off countries, which OECD countries are, we don't have time to be depressed and seek chemical solutions to 'get rid of it'."

Dr Jordi Alonso, director of the programme of epidemiology and public health at the IMIM-Institut de Recerca hospital del Mar in Barcelona, Spain, said: "In my opinion, one major issue is that GPs have become familiar with the indications and results of antidepressants. Possible explanations of this fact are the time elapsed since new SSRIs were available and of course, the dissemination and publicity about their efficacy – with the lead of the companies who have produced them."

Mening: Depressie is ,denk ik, een ziekte van deze tijd/maatschappij, althans de grote toename ervan. Ik vond het wel interessant in het artikel hoe ze aanhaalden dat mensen en dokters depressie nogal gauw verwarren met ongelukkig zijn, wat iets natuurlijk is bij de mens en niet noodzakelijk op dezelfde lijn als depressie staat. We zijn een heel verwende en ongeduldige samenleving die door middel van de steeds meer geoptimaliseerde globalisatie met van alles en nog wat in contact komt dat over de hele wereld gebeurt waardoor we ons ongelukkig voelen.

Vroeger leefden mensen in een kleine,gesloten gemeenschap met weinig of geen kennis wat er allemaal gebeurde in de rest van de wereld. Deze vorm van onwetendheid maakte ons denk ik veel gelukkiger omdat we ons eigen hebben en zijn enkel in vergelijking stelden met de kleine gemeenschap waarin we leefden, die vaak overeenkwam.
Globalisatie maakt ons hebzuchtiger en creëert vaak veel te hoge verwachtingen waardoor we ons nogal sneller ongelukkiger voelen.

Net zoals de bedrijven ons ook steeds weten te overtuigen hoe belangrijk het is de nieuwste snufjes te hebben. Het is vrij verbazend om te zien hoe materialistisch sommigen zijn en hoe snel we ongelukkig/teleurgesteld zijn wanneer we iets niet hebben. De decadentie van het kapitalisme is dus denk ik ook wel een grote factor bij depressies/ongelukkig zijn.

Nu weet ik wel niet wat het meest effectief is; een langdurige behandeling met een psycholoog/psychiater of meteen grijpen naar pillen. Ik vermoed dat een combinatie van beiden een optimaal resultaat bereikt en ga dus geen pleidooi starten over hoe slecht het is om pillen te nemen.
Ik vermoed wel dat het aantal depressies enkel in de toekomst zal toenemen en niet afnemen, we worden steeds meer en meer verteld hoe we moeten leven, wat we moeten hebben of zijn om aan de normen van de maatschappij te voldoen en velen onder ons zullen een diepgeworteld gevoel van ongeluk ervaren wanneer dit niet lukt.
