New drugs are the ones you hear about most. Drug companies can charge more for brand-new drugs before generics horn in on the territory, so it pays to advertise them and to fund studies that get doctors thinking about how great they are. Older drugs don’t get as much press.

But doctors and scientists have had more time to get to know the older drugs. If there’s a long-term risk or a subtle side effect, it might not be obvious at first. So even if a new drug is the one on the tips of prescribers’ tongues, an older drug is sometimes a more solid choice.
In Australia, advertisements for all therapeutic goods (including medicine and medical devices) is controlled by the Therapeutic Goods Administration and only non-prescription medicines – over the counter and non-prescription complementary medicines – can be advertised to consumers. Prescription medicines can only be advertised to health professionals.
That’s one of the “golden rules of drug therapy” from clinical pharmacologist Andrew Herxheimer, who died at age 90 earlier this year. Medical journal The BMJ remembered him with a blog post that included his nine rules intended to assist patients. Here are the first three:
- Think what you could do instead of using a medicine.
- Unless you have a special reason, avoid new medicines. Stick to those about which a lot is known from many sources and which have been used for over 10 years; bad news about a drug often takes years to emerge.
- Before deciding to use a medicine be clear whether it is to relieve a symptom, to cure a disease, to remedy some deficiency, or to prevent something. It doesn’t make any sense at all to prevent something in the future if it’s going to cause you some problem now.
