The New York Times has recently published
two articles
on the use of so called nutritional supplements. Nutritional supplements are
not regulated as drugs, but physicians and hospitals should, and usually do,
treat them as drugs. What does this
mean? Supplements do not have to prove that they are efficacious and safe
before they are sold. The FDA can only
regulate them in a retrospective way – when they find that there may be a
problem. It’s like the FDA and food safety, at least until recently. Only after the problem occurred, when it was
too late, could the FDA crack down on a malfeasant food supplier. Same deal for
supplements.
The FDA is now spending a great deal of its enforcement time
dealing with supplements that have unlabeled active ingredients like steroids
or Viagra-like drugs or amphetamines. Some have high quantities of things like
arsenic or heavy metals like lead and selenium.
Some are just mislabeled so instead of getting gingko, you’re getting
green tea or just twigs and leaves. All of these can be harmful to your
health. And – you don’t know that you’re
taking them because you think that the supplement you are taking for your joint
health or whatever is safe and effective.
You believe all those advertisements on TV. Or you mistakenly believe that somehow the
FDA has your back here. You’re wrong on
all counts. By the way – the FDA is not alone here – same problems in
Europe. My impression is that
supplements are even more popular there than in the US.
Steroids in supplements can lead to masculine traits in
women like beard, mustache or chest hair.
They can lead to breast enlargement in men. But, in the worst case, they can lead to
liver failure as noted in the second
article in the Times. Liver failure can sometimes be treated with
medication and watchful waiting, but sometimes a liver transplant on an
emergent basis is the only alternative.
Sometimes, you die.
Another recent study looked at the utility
of those vitamin pills many of us take every day. Guess what!
They don’t do anything. But, in some cases, like the other supplements,
they can be harmful or contain unlabeled contaminants. Admittedly, the problem of unlabeled or mislabeled
ingredients seems to be less urgent for vitamins – at least our risk of dying
from taking them seems to be less than for other supplements – but they don’t
seem to do anything to benefit us either.
What does all this have to do with antibiotics and why is
this topic appearing in this blog? Well, supplements have always been a pet peeve
for me and the latest spate of lay news articles has given me the opportunity
to vent a little. But, some “natural” practitioners are recommending that one
way to cut down on inappropriate antibiotic use – a noble goal – is to use
nutritional supplements of various sorts instead. Obviously – I think this is a
very bad idea. If you don’t need an
antibiotic because you have a viral infection that antibiotics won’t treat –
don’t take them. But if you have a
potentially serious bacterial infection and you try to treat it with some
supplement – you’re playing Russian roulette.
