For generations of physicians, the prevailing teaching was not to prescribe too many drugs in order to avoid unwanted side effects. No longer.
“What we’ve seen is a massive rise in reliance on medicines as a panacea for all our woes,” says Clare Gerada, former chair of the UK’s Royal College of General Practitioners. “There’s been a big rise in screening to look for diseases before they happen, and we have begun treating people ‘just in case’.”
As lifespans stretch, many of us are popping at least one pill a day. But all this medicine could be harming rather than helping your health.
When did you last pop a pill? The chances are it was recently, no matter how healthy you are. A growing number of us are taking medicines as part of our daily routine, not because of illness, but to prevent it. A recent survey found that 43 per cent of men in England and 50 per cent of women had taken a prescribed drug within the past week, and half of those had taken three.
Just how much of what the NHS offers to patients is unnecessary was dramatically addressed 38 years ago in a seminal 1974 paper in The Lancet. In Medical nemesis, Ivan Illich coined the phrase "medicalisation of health", postulating that, as well as doing good, medicines can cause clinical and societal harm. Since then, prescribing has become the dominant medical intervention in primary care, and its benefits and risks are increasing in the balance.
