The story below is conventional but unbalanced. Phenacetin is said to be the ingredient in APC powders that caused kidney damage but what does it metabolize to in the body? Paracetamol! Precisely the analgesic that is now generally recommended. How crazy can you get? And paracetamol (aka acetaminophen) IS dangerous by itself, but not for its effect on the kidney. It destroys the liver! It is very dosage-sensitive. If you take much more than the recommended dosage, you can die.
So how come people took huge doses of phenacetin and did NOT die of liver disease? And aspirin in large doses can be toxic too, though not nearly as toxic as paracetamol. So people were taking huge doses of both paracetamol and aspirin without experiencing the symptoms that should have gone with that. So again, How come?
It seems that the APC combination produced some sort of beneficial drug interaction. The three ingredients seemed to combine to eliminate the toxicity they had by themselves. Stranger things have happened. But divine miracles are rare so to a small degree the APC combination also caused some damage -- but only to the kidneys and only among heavy users of the powders. And the mortality from liver disease is now much greater than the mortality that used to be experienced from kidney disease.
So APCs were in fact a wonder drug that became harmful only from heavy over-use. And ANYTHING can be harmful in excess. Even drinking too much water can kill you. Google "hyponatremia" if you doubt it.
Another problem is that many Bex users went onto Valium instead when Bex was withdrawn -- with its attendant risk of making you drowsy when you're driving. So did the ban on Bex kill people in road accidents? Probably.
And a VERY important use of Bex was as an early treatment for what is still a dreaded and all too common ailment: migraines. Migraine sufferers generally get some warning when a migraine is due to strike, an aura, jaw stiffening etc. And as soon as anybody prone to migraines felt the slightest suspicion that one was about to strike, they would grab their nearby packet of Bex and slam one into themselves quick smart. And it did help. If you got the Bex into yourself straight away, the migraine would either not develop or would be less severe than a full-blown attack.
Now here's the final kicker: Something that is often prescribed for aches and pains these days is NSAIDS (Ibuprofen etc.). And guess what is a major side effects of NSAIDS? Kidney damage. NSAIDS are hundreds of times more toxic to the kidneys than Bex ever was. So let's ban NSAIDS!
So I know I am telling here a story that is at great variance with the conventional wisdom but everything I have said above is entirely factual. There was some research in the 1960s that pointed to the benefits of the APC combination but it was not pursued, presumably because the usefulness of APCs was seen to be beyond question and needing no reinforcement

I am inclined to suspect that the main reason for banning APCs such as Bex was because they were so popular. That HAD to be bad
WHEN former prime minister Kevin Rudd told journalists speculating that he was trying to reclaim the Labor leadership to have "a cup of tea, a Bex and a good lie down", younger members of the media pack look puzzled.
They had not heard such an expression before, but to the children of the Baby Boomer generation, the phrase was immediately recognisable.
It was in the late 1950s and throughout the ’60s that the marketing slogan entered the vernacular. Bex, the analgesic made up of aspirin, phenacetin and caffeine (APC), became an Australian icon. It was recommended to treat aches and pains, headaches, colds, flu, fevers, rheumatism and for "calming down".
Dissolving a Bex (or the similar product, Vincent’s) in a cup of tea, or taken with other stimulants such as cola drinks became particularly common among housewives. It was widely available and sometimes taken up to three times a day.
Aggressive marketing from drug companies meant it was even common to pop a Bex or Vincent’s powder in children’s lunch boxes "just in case".
It wasn’t until the 1970s that doctors and health experts realised these formulations were responsible for kidney disease and addiction, and were carcinogenic. Phenacetin was finally pulled from the market by the late ’70s. But the damage had already been done. In the years that followed World War II, Australia led the world in APC consumption — and in the number of deaths it eventually caused.
Women resorted to "a cup of tea, a Bex and a good lie down" so often that in 1965 it became the title of a popular play by John McKellar.
The phrase is still instantly recognised by the children of that generation. So many people had an aunt, a mother, a sister, or a friend who were addicted to APCs. Many of them died from related kidney disease.
Readers of our Adelaide Remember When Facebook page recently responded to a post on the Bex phenomenon with memories of their own experiences.
Rick Cooper wrote: "For a while, I lived in Hamley Bridge and the railway was the playground, transport and just about everything else for us kids. At one stage, Vincent’s had a sign on every fence along the railway lines with the countdown in miles until you reached Adelaide. The blue, yellow and white signs said ‘X miles to relief with Vincent’s powders’."
Trish Simpson recalled how her father was addicted to Bex and ended up with terrible kidney problems: "We always had Bex in the house and I remember taking them when I was younger. Eventually they removed the damaging ingredient and Bex wasn’t as effective. Not sure how much longer they survived after that."
Vincent’s Powders and Bex with aspirin and cold medicine on the shelf in 1979.
Deborah Wise reminisced that as a child she loved Bex: "If we had a sore throat, Mum would mix a powder in a teaspoon of honey. Man, it tasted good! I suppose it eased the symptoms as well. I’m pretty sure that my Dad used to take a Bex first thing every morning."
And Adele Andrews contributed: "I was an operating room nurse in the late 1960s and one of Adelaide’s top renal surgeons gathered all the OR staff into the theatre one day to show them a shrivelled-up kidney he had just removed from a 32-year-old woman. All he said was ‘Bex powder addiction, take note’. I had never taken any APC and was not about to start after that lecture. They should have been banned much earlier."
Concerns about the rates of consumption of the popular analgesics first surfaced in 1962 and resulted in a series of public health warnings.
They seemed to have a minimal impact until 1966, when kidney specialist Priscilla Kincaid-Smith — after noticing a serious rise in women presenting with kidney disorders — conducted a series of experiments on rats.
She proved that APC powders were linked to serious kidney disease and the Government of the day began to take notice. In 1967, the National Health and Medical Research Council recommended that phenacetin be removed from the pharmaceutical benefits list, which saw Vincent’s eliminate the compound from its powders that same year, replacing it with salicylamide, which was from the same chemical family as aspirin.
Bex, however, continued to include phenacetin in its product but the sustained adverse publicity throughout the 1970s and the mounting evidence that the once "harmless" cure-all was in fact causing serious kidney disease, forced Bex to also drop the substance from its powders in 1975. By 1977, the results of the addiction were becoming very clear and the NH & MRC moved to restrict the availability of all APCs.
And so the Bex and Vincent’s powder era, thankfully, came to an end.
Thinking back to those days, it was just part and parcel of the lifestyle. Just about everyone’s mum or grandma seemed to always have a Bex or Vincent’s powder handy and, with the first sign of a headache, a cold or if they felt they needed a quick "pick me up", down would go a powder.
It was a vicious circle of addiction, really: the caffeine content gave a sudden rush of energy, which eventually triggered a withdrawal headache, which prompted them to take another powder

There are plenty of reasons why waking up in the morning is the grimmest thing we'll do all day.
But daybreak is even more dolorous if we're unlucky enough to wake up with our eyes glued shut.
When this happens, we generally say that we've awoken with 'sleep in our eyes'.
But in America, the horrid peeper adhesive is called "eye boogers" - which makes it sound a million times more disgusting.
Now the science experts from a YouTube channel called SciShow have stepped in to explain the make-up of this yucky substance.
Michael Saranda, host of the show, said : "Mr Sandman, I asked you to bring me a dream and you brought me were these gross eye boogers.
"So what is this goopy junk which collects in the corners of my eyes while I'm asleep?"
He explained that scientists don't have an official name for the "crusty residue", although it is often referred to as rheum or gound.
Rheum is always present in the eye, which uses a liquid called "tear film" to keep the peeper lubricated.
When we wake up, the tear film has gathered in our eyes because we haven't been blinking.
It has also become mixed with oil, bacteria, dust and skin cells to produce a sticky substance which glues the eye shut.
"Before you know it you have eye boogers in all their crusty, cruddy glory," Saranda added.
Americans also refer to eye boogers as "dream dust" and "sleep sand" - which, in Britain, would probably be names given to legal highs.
