Since Advil, Tylenol, and Aspirin are all common pain-relieving medications, it can be pretty confusing remembering all the differences between them. While many will admit they know the three medications don’t all work the same way, not many can say what the differences between them are.
Advil, Tylenol, and Aspirin each have a unique function, and a specific kind of pain that they’re better suited to relieving. These over-the-counter pain meds also have very different side effects. You may have a go-to pain med that you instinctively reach for whenever you feel any type of pain coming on, but this guide will help you break that pattern. Using the information below, you’ll be able to properly assess which medication to choose to relieve the particular pain that you happen to be feeling.
Medical Name: Ibuprofen
The Science Behind How Advil Works
Advil is a nonsteroidal anti-inflammatory. It works by preventing COX 1 and COX 2 enzymes from creating the compounds that can increase pain and inflammation in your body.
When to Use Advil
Advil works on the affected location of any injury that causes pain and/or inflammation. If the pain itself is caused by an inflammation, Advil will directly help to alleviate it. This is in contrast to Tylenol, which works centrally to increase your pain threshold.
For inflammatory pain, Advil works best. If you’re hoping to get rid of the cause of the pain, and not just reduce the amount of pain you’re feeling (which is what Tylenol does), taking Advil is a good fit.
Advil’s Side Effects
These will of course depend on each individual. The following symptoms are uncommon but can happen: upset stomach, mild heartburn, diarrhea, constipation, gas, bloating, dizziness, headaches, nervousness, rashes, blurred vision, or tinnitus.
Medical Name: Acetaminophen
The Science Behind How Tylenol Works
Tylenol is an analgesic that inhibits production of cyclooxygenase (COX), which then blocks the production of prostaglandins. Unlike most non-opioid alagesics, it doesn’t block CO in the peripheral nervous system to an appreciable extent.
When to Use Tylenol
Tylenol is a relatively weak analgesic that should be used for headaches, fevers, and minor aches/pains. Tylenol is not ideal for sprains or pain as a result of inflammation, as it does not possess anti-inflammatory properties like Aspirin and Advil do. It works very well to increase your resistance to feeling or sensing pain, and as such is considered efficient at reducing fevers and general bodily aches.
For general pains and aches, then, take Tylenol. For fevers and headaches, Tylenol is also ideal.
Tylenol’s Side Effects
If taken incorrectly, Tylenol can actually cause liver damage. Stop taking Tylenol and immediately consult a doctor should you have any of the following symptoms: jaundice (yellowing of the skin or eyes), dark urine, and/or clay-colored stools. Nausea, stomach pain, and a loss of appetite can also occur as side effects of taking Tylenol.
Medical Name: Acetylsalicylic Acid
The Science Behind How Aspirin Works
Aspirin works in two ways:
- It’s part anti-prostaglandin, which works to reduce fever, general pain relief, and inflammation (just like Advil).
- It’s also part anti-platelet agent, which acts as a blood thinner by inhibiting production of thromboxane, which is what binds platelets together.
When to Use Aspirin
Aspirin is great for regular headaches, to reduce swelling of joints, for mild fevers, and as a part of an everyday regimen (in low doses) to combat various disorders like Ischaemic strokes, dementia, heart attacks, and certain types of cancer like bowel cancer.
Aspirin is ideal for everyday use in small doses (under 100 mg) because it helps to circulate the blood in your body, and is especially ideal to use during the onset of and after a heart attack, as it reduces chances of heart attacks recurring.
Aspirin is not ideal for migraines or severe pain, as it may not be sufficiently strong enough to reduce extreme pain. Aspirin’s anti-inflammatory properties, while similar to Advil’s, are not as strong as Advil’s. So if you’re looking for the strongest anti-inflammatory medication, again, don’t use Aspirin, use Advil instead.
Aspirin’s Side Effects
When using Aspirin, there is risk of stomach ulcers and irritation. If you happen to get the Aspirin pills that come with an Enteric coating, however, these protect the stomach lining, thus dramatically reducing the likelihood of stomach ulcers from occurring.
Its abilities as a blood thinning agent should be kept in mind if you are bleeding, as aspirin can exacerbate the flow of blood.
For those who like to skip to the end, the conclusion is that Avil is ideal for inflammatory pain, as it prevents your body from producing the enzymes that can cause inflammation and pain, Tylenol is ideal for general pain, as it raises your pain threshold, and finally, Aspirin acts as a weaker anti-inflammatory medication to Advil, as well as having the added benefit of being a blood thinner that can be used as a daily supplement, thus making it ideal for mild headaches and heart attack prevention.
Next time you reach for a pain med, think about which one of these three common over-the-counter pain medications will help you out the most. You may find yourself reaching for a different bottle than you’re used to.
