17 Interesting Facts About Painkillers

Pain is a sensation we all know too well. From the ache of teething as a baby to the acute agony of a wound, to the chronic ache of arthritis, pain comes in all forms.

Naturally, as innovative people strive to lessen the discomfort of life in a tender, physical body, we have developed a fix: Pills. Painkillers. Analgesics. Call it what you will, it is a multi-billion dollar industry that has afforded people both incredible, life-serving relief from debilitating pain and has also created a culture dependent on the reprieve from suffering that a pill can offer.

The story of painkillers is as nuanced the pain we are capable of feeling. We’ve gathered up some of the most interesting and need to know facts so you can be well-informed on one of the most taken-for-granted medicines available to us.


  1. Three in five Americans have used a non-prescription medication in the past 6 months and of that 78% were painkillers[1]

More than 2.5 billion dollars are spent on non-prescription painkillers each year[2] and roughly 8 in 10 Americans routinely use over the counter (OTC) painkillers.[3] Whether for backaches, head aches or sore muscles, people do not hesitate to reach for pain relief.

However, problems can arise when people ignore dosage labels, leading to all kinds of physical complications. Studies indicate that there is widespread overuse of OTC painkillers in America. [4]


  1. There are 2 primary types of over-the-counter painkillers

Of the over-the-counter pain pills available, there are two primary types which work in different ways. They include: Analgesics and NSAIDS (Non-steroidal anti-inflammatory drugs).

Analgesics include Acetaminophen—of which Tylenol and Paracetamol are brand names—and Aspirin. They help to control pain by blocking or manipulating pain signals sent to the brain. They also reduce fever.

NSAIDS include drugs such as Ibuprofen (brand names include Advil and Motrin) and naproxen sodium (such as Aleve). They work by decreasing the production of pro-inflammatory chemicals known as prostaglandins, thus reducing both pain and swelling.

Some painkillers will utilize a combination of painkilling chemicals—such as acetaminophen, aspirin and caffeine.


  1. NSAIDS can lead to higher risk of heart attack[5]

As mentioned above, NSAIDS work by blocking chemicals known as prostaglandins, which cause swelling and pain in response to various conditions in the body such as an injury. However, since prostaglandins are also responsible for a healthy cardiac system, blocking them can lead to an increased risk of adverse heart conditions, such as a heart attack or stroke.

Long term use of NSAIDS can increase blood pressure and should be avoided if you have hypertension.


  1. Overuse of NSAIDS can cause stomach bleeding

NSAIDS are also hard on the stomach and gastrointestinal tract and can cause bleeding and ulcers when overused. They are also hard on the liver and esophagus. A national poll by the American Gastroenterological Association found that on average gastroenterologists see on average nearly two patients per week for complications from over-the-counter pain pills.[6]


  1. Painkillers can damage your kidneys

High doses of painkillers on a regular basis can lead to temporary or permanent kidney failure. This is because the kidneys must process all of the painkillers we consume which can have a damaging effect on kidney tissue and structures. To relieve the stress on your kidneys drink plenty of water when taking pain medication and avoid alcohol.


  1. Aspirin is the only painkiller known to reduce chances of heart attack[7]

In addition to relieving pain, aspirin also thins the blood, slowing the clotting action.[8] Individuals who are at risk of heart problems, can develop blood clots that can stop blood flow to the heart, causing heart attack or stroke. Low dose aspirin therapy is a common treatment.  In these low doses, it is unlikely to damage your kidneys.


  1. The original Aspirin recipe used Willow bark

In fact, most medications were originally—or still are—derived from plants. Many of the plants with the most effective chemicals have since been synthesized in labs. Pain medications are no exception. Both Willow and Meadowsweet—as well as other plants— contain the precursor for salicylic acid, which is the chemical that is so effective at reducing pain in humans.

In fact, Willow bark has been used since ancient times (it’s conjectured since about 3000 BC!) to treat pain. It wasn’t until the 1800s that Joseph Buchner effectively extracted the active ingredient and called it Salacin. Then, in 1853, Charles Frederic Gerhardt succeeded in chemically synthesizing the structure of salicylic acid.[9]

In 1897 Bayer created Aspirin by combining salicylic acid with an acetyl group which effectively diminishes the irriating side-effects of taking salacin directly. The name aspirin actually comes from the combination of A for acetyl group and “spir” from the latin name for the naturally salicylic acid- containting Meadowsweet, Spiraea ulmaria.


  1. Prescribed pain killing medications include Opioids, Steroids and Benzodiazepines

Opioids, also known as narcotic analgesics, work on opioid receptors found in the brain and spinal cord blocking pain and making you feel calm and happy.

Steroids decrease inflammation and thus any pain associated with inflammation.

Benzodiazepines are sometimes prescribed in cases where the psychological aspect of pain is especially severe, causing anxiety.[10] It is also a muscle relaxant and can thus help relieve muscle pain. Use of benzodiazepines for pain are highly controversial due to their addictive nature and unclear evidence as to the actual benefit as they relate to pain.[11]


  1. Opiates are inspired by the Poppy Plant

Just as Aspirin originally comes from Willow, so does the original opiate come from the Poppy plant, in the form of opium.  After scoring the plant and collecting the latex that bleeds from the immature seed pod and stems, opium was smoked.

Later, the process of creating Laudanum, or Opium Tincture was developed. It was the primary pain medication used for just about everything from the 1600s until the 20th century when the addictive quality came under scrutiny and it was removed from the market. Effective though it was, it had the unpleasant side effect of delusional dreams.


  1. The U.S. contains only 4.6% of the world’s population but consumes 80% of the world’s opiates.[12]


It’s no secret that there is a huge opium epidemic hitting communities across America.[13] The National Institute for Drug Abuse estimates that 2.1 million people in the US are currently suffering from an opioid painkiller addiction.[14] While opiates are excellent for pain relief, they are highly addictive and when abused are deeply damaging to health, up to and including death.



  1. There are 3 classifications of opiates

Natural opium derivatives like Morphine come entirely from the Poppy plant.

Partially synthetic opiates are like they sound: part natural and part synthesized. They include heroin, oxycodone and oxymorphone.

The last classification is the completely synthetic derivatives such as codeine, fentanyl and methadone.


  1. Heroin was originally developed to help with Morphine addiction

Actually, Morphine was developed to help wean people off of opium addiction, not realizing that morphine addiction would become the next big problem. Ironically, heroin was then developed to help wean people off of morphine addiction. The problem was that each subsequent drug was more euphoric and addictive than the last. It wasn’t long before heroin was classified as an illegal drug in the US.


  1. More Americans die every day from drug overdoses than from car crashes. The majority of those deaths involve legal prescription drugs.[15]


Prescription drugs are the most abused category of drugs in the US. In 2007 at least 12,000 Americans died from prescription pain relievers.[16] In 2014 28,000 people died from opiate overdose, half of which were prescribed.[17][18] The number of deaths continues to grow every year.


  1. Athletes are at risk of becoming abusers of pain killers[19]

Athletes are known for pushing themselves in remarkable ways on the field or court. But while they may accomplish extraordinary feats of the body, it can often be at a cost. Pushing hard often leads to injury and pain, which is why this group tends to be susceptible to overuse of pain pills. Painkillers can help athletes push through discomfort while remaining just as active.

The problem with this line of reasoning is of course that overuse of pain medications is hard on the liver and kidneys. Also, covering the pain instead of letting the injury heal can lead to further injury. If pain exists it is often due to swelling which is a cry from the body for some rest and time to recuperate. [20]


  1. Americans spend $50 billion a year on back pain relief [21]

Back pain is the most common type of pain condition reported in America and one of the primary conditions for which sufferers require pain killers.[22] Headaches are the next most cited pain.


  1. Smokers need to take more medication than those who don’t smoke in order to get the same relief

Unfortunately for smokers, it turns out that in addition to all the other risks associated with smoking, it also interferes with pain medication. Smokers require more over the counter and prescription painkillers than their non-smoking equivalent.[23] Smokers are also 3 times more likely to suffer from back pain thanks to the fact that tobacco impairs the delivery of nutrient flow to the discs of the spine, which can cause degeneration.[24] [25]


  1. Women are less likely to be given painkillers even though they experience more pain

Scientific America reported on one study that indicates women experience pain more intensely than men.[26] However, multiple studies and reports indicate that doctors are less likely to take complaints of pain from women seriously.[27] For example, one researcher found that women were more likely to receive sedatives instead of pain killers even when exhibiting identical symptoms for the same ailment as a man (who is more likely to receive painkillers).[28]
