When Are NSAIDs Like Ibuprofen Actually Appropriate?

TL;DR

NSAIDs such as ibuprofen and naproxen reduce the inflammatory soup of prostaglandins, histamines, and cytokines released after injury. Take them when they restore function, but keep courses short (one to two weeks), take with food, and watch blood pressure, heart, and kidney risks, especially in older patients. Response varies greatly between individuals.

Um, but why don't we start with a softball like NSAIDs? How do they work? You know, everybody's heard of Advil, you know, Alie, neproxin, all of these things. What they do is a couple things. They reduce some of the inflammation. They're anti-inflammatories. So I was alluding very briefly that there are substances that can be released out in the pe... Read More

Key Insights

• NSAIDs work by reducing inflammation, knocking down the inflammatory soup of prostaglandins, histamines, cytokines, and interleukins released during injury that amplifies nociceptors, classically shown as swelling, redness, and temperature increases.
• The appropriateness of NSAIDs is a gray-area judgment call: if pain is minor and function is unaffected, skipping the drug may aid healing, but if an NSAID lets a person get out of bed and engage with work and family, taking it is worthwhile.
• Emerging evidence questions whether suppressing inflammation is always good, since inflammation may be part of the natural healing process; orthopedic data decades ago linked NSAID use during total joint replacements to nonfusion and failures.
• Chronic long-term NSAID use introduces broader negative consequences including impact on blood pressure, the heart, and kidneys, with risks heightened in older patients.
• A safe ibuprofen course is roughly 800 mg three times a day (2,400 mg total) tolerated for one to two weeks, taken with food and fluids, with a doctor consulted first if the person is older or has kidney or GI issues.
• Acetaminophen and ibuprofen have a useful synergy because they use different mechanisms and impact different organ systems, so combining them lets you take less of each, making one plus one feel like three.
• Acetaminophen's mechanism is still poorly understood, thought to act largely centrally, with some studies suggesting emotional blunting in the brain; historical dosing was up to four grams a day, more recently pushed toward two grams.
• Individual variability in NSAID response is large, likely tied to pharmacokinetics and how different NSAIDs permeate tissues, so an empirical approach of trying naproxen versus ibuprofen to find what works is recommended.

Questions & Answers

Q: How do NSAIDs like ibuprofen and naproxen work?

NSAIDs are anti-inflammatories that reduce inflammation. During injury, substances are released in the periphery that amplify nociceptors, creating an inflammatory soup of prostaglandins, histamines, cytokines, and interleukins after every surgery or injury. This inflammation is classically mediated by swelling, redness, and temperature increases. Aspirin and COX-2 inhibitor NSAIDs do a nice job reducing that inflammation and the associated pain.

Q: Should you always take NSAIDs to knock down inflammation after an injury?

Not necessarily. Medical science has been shifting its view. Historically the thinking was to take these medications for acute injury to knock down inflammation. But orthopedic data decades ago showed people taking NSAIDs during total joint replacements got nonfusion of the joint to bone and failures. More recently there is a question of whether inflammation is part of the healing process, meaning NSAIDs may delay natural healing and cause more problems.

Q: When is it appropriate to take an NSAID versus skip it?

It is a gray-area, individualized decision. If the pain is something minor and a person can get by without the NSAID without significantly changing their level of function, then not taking it may improve healing. But if they cannot get out of bed or go to work and a medication like naproxen helps them engage with family, friends, and work, then taking the NSAID is worthwhile for that functional improvement.

Q: What are the long-term risks of taking NSAIDs?

With chronic long-term NSAID use, broader negative consequences emerge, including impact on blood pressure, the heart, and the kidneys, particularly in older patients. NSAIDs can also cause GI issues. Because of these risks, anyone who is older or has kidney or GI issues should talk to their doctor before taking them and should not go into it blindly.

Q: What is a safe dose and duration for ibuprofen?

A commonly discussed regimen is 800 mg of ibuprofen three times a day, totaling 2,400 mg, which can be tolerated for about a week to two weeks if a person needs it. It should be taken with food in the stomach and fluids. Anyone who is older or has kidney or GI issues should talk to their doctor first rather than taking it blindly.

Q: Why combine acetaminophen and ibuprofen together?

There is a nice synergy between acetaminophen and ibuprofen because they have different mechanisms of action and impact different organ systems, so you can take less of each when combining them. The effect is described as one plus one not equaling two but three. This combination is used to get the twofer synergy, for example a stack of 400 mg of Advil and 500 mg of Tylenol three times a day.

Q: What types of pain do NSAIDs work best for?

NSAIDs are the typical go-to for nociceptive pain and nociceptive inflammatory pain, the kind you would see in a joint. They also work for back pain, particularly in acute situations but also somewhat in chronic cases. They are not as effective for neuropathic pain, where they might only take a little bit of the edge off rather than resolving it.

Q: Why do people respond so differently to different NSAIDs?

There is huge individual variability in responses to NSAIDs. In part this has to do with pharmacokinetics, or where the drug is getting to, since different NSAIDs can permeate different tissues at different rates. Because of this, an empirical approach is recommended: try naproxen, try ibuprofen, and figure out which one works for you, without taking them together.

Summary & Key Takeaways

• NSAIDs like Advil, Aleve, and naproxen, along with aspirin and COX-2 inhibitors, reduce the inflammatory soup of prostaglandins, histamines, cytokines, and interleukins that follows every surgery and injury. This inflammation is classically mediated by swelling, redness, and temperature increases and amplifies pain-signaling nociceptors in the periphery.

• Medical science is shifting on whether suppressing inflammation is beneficial. Older orthopedic data tied NSAID use during joint replacements to nonfusion and failures, and inflammation may be part of healing. The decision is individualized: skip the drug for minor pain, but take it when it meaningfully restores function.

• For dosing, ibuprofen at 800 mg three times daily is tolerable for one to two weeks with food and fluids. Combining acetaminophen and ibuprofen gives synergy across different mechanisms and organ systems. Response varies individually, so an empirical trial of naproxen versus ibuprofen helps identify what works best.
