ANTIDEPRESSANTS

Doctors have been getting it wrong about antidepressants for years. So wrong, in fact, that they’re putting at risk the lives of teenagers and young adults, who are far more likely to commit suicide while taking the drugs.

The risk is so great that America ’s drug regulator, the Food and Drug Admin istration (FDA), has told drug manufacturers to strengthen the warning about suicidal tendencies, especially among patients aged between 18 and 24 years.

The risk is highest during the ‘initial period’, which is generally considered to be within the first four to eight weeks. This view of the initial period goes back to the 1950s, when the first generation of antidepressants came to the fore – and this is where doctors have got it so wrong.

It’s always been believed that antidepressants have a “delay in on set of effect”, as drug companies put it, which means that they don’t start working right away.

But this just isn’t true. A 2005 meta-analysis of 76 different trials found that 60 per cent of patients reported an improvement in the first two weeks after starting antidepressant therapy.

A study last year, which looked only at SSRIs (selective serotonin reuptake inhibitors), a special type of antidepressant, found that all the beneficial effects happened in the first week of treatment, if they were going to happen at all.
