What Is the Best Over-the-Counter Medicine for Body Pain?
For most types of body pain, ibuprofen 400mg is the best over-the-counter option because it targets the inflammation causing the pain directly. But paracetamol is the safer choice if your stomach is sensitive, and naproxen sodium lasts longer if you need all-day relief. The right choice depends on your specific type of pain, your health history, and whether you have a stomach ulcer or kidney concerns.
This guide covers exactly how each OTC pain medicine works, which one fits your situation, and — just as importantly — the mistakes I see people make at my counter every single day.
Understanding Body Pain: Why the Type of Pain Matters
Body pain is not one thing. Knowing the source helps you choose the right medicine — and avoid one that does nothing for what you actually have.
Pain falls into two broad categories: inflammatory and non-inflammatory. Inflammatory pain happens when your immune system releases prostaglandins — chemical messengers that trigger swelling, heat, and pain — at a site of injury or infection. Muscle aches after exercise, joint pain from arthritis, menstrual cramps, dental pain, and the full-body aches that come with influenza all have a significant inflammatory component. Non-inflammatory pain — like tension headaches or nerve pain — is processed differently.
This distinction matters because paracetamol and NSAIDs work through entirely different pathways. NSAIDs block the production of prostaglandins at the source of pain. Paracetamol works centrally on pain signal processing in the brain. And for inflammatory body pain, NSAIDs win on mechanism. For mild-to-moderate pain without significant inflammation, both can work.
💡 Key Takeaway
Identify whether your body pain is likely inflammatory — muscle soreness, joint ache, flu-related ache — before reaching for a pain reliever. That distinction changes which medicine actually works for you.
The 3 Main OTC Pain Medicines for Body Pain — Compared
There are three OTC analgesics you will find in every pharmacy: paracetamol, ibuprofen, and naproxen sodium. Each has a specific profile of strengths and risks worth understanding before your next dose.
| Medicine | Standard Adult Dose | Onset / Duration | Best For | Key Risk |
|---|---|---|---|---|
| Paracetamol | 500–1000mg every 4–6 hours (max 4g/day) | 30–60 min / 4–6 hours | Mild-moderate pain, fever, ulcer patients, children | Liver damage in overdose — especially with alcohol |
| Ibuprofen (NSAID) | 200–400mg every 6–8 hours (max 1200mg OTC/day) | 20–30 min / 4–8 hours | Muscle pain, joint pain, menstrual cramps, flu aches | Stomach irritation, kidney stress — always take with food |
| Naproxen Sodium (NSAID) | 220mg every 8–12 hours (max 440mg OTC/day) | 30–60 min / 8–12 hours | All-day or overnight pain relief, arthritis aches | Stomach irritation — stronger GI risk, not for frequent use |
The most common error I see is people reaching for paracetamol out of habit — even when their pain is clearly muscular and inflammatory. Paracetamol will not make a meaningful dent in that kind of pain. The person takes it, feels no relief, doubles the dose, and comes back the next day still hurting. But the answer was ibuprofen from the start.
💡 Key Takeaway
Ibuprofen is the better first choice for most adults with body pain from muscle injury, flu, or joint inflammation. Paracetamol is safer for people with stomach ulcers, kidney concerns, or those on blood thinners. Naproxen sodium works when you need fewer doses across the day.
If you are looking for a supplement to support muscle recovery alongside OTC pain relief, MSM (methylsulfonylmethane) has solid evidence for reducing exercise-related muscle soreness and joint discomfort:

Ibuprofen vs Paracetamol: Which Is Better for Body Pain?
This is the question I answer more than almost any other. Both medicines are safe when used correctly. But they are not interchangeable.
Choose ibuprofen if: your pain follows an injury, exercise, a fever-related illness, menstrual cramps, or joint inflammation. It reduces the prostaglandins that cause swelling and soreness at the site of the problem. Take it with food or a full glass of water — always.
Choose paracetamol if: you have a stomach ulcer, chronic gastritis, or you are currently taking aspirin or blood thinners. Paracetamol is also the right choice for children's fever and pain, and for pain during pregnancy — always under medical guidance. But the maximum safe dose is 4 grams per day for a healthy adult. Many people unknowingly exceed this by combining paracetamol with cold and flu tablets that also contain it.

The combination question I answer most often — easily several times a week — is whether paracetamol and ibuprofen can be taken together. Most patients are not asking because they are curious. They have already taken both and are worried, or they plan to take both because one alone is not working. The most dangerous misunderstanding I correct is that taking both simultaneously makes the pain relief stronger. It does not. Paracetamol acts centrally on pain signals; ibuprofen reduces inflammation at the site. They can be used in a staggered schedule — one every three hours alternating — but they should not be swallowed at the same time. And ibuprofen should never be taken on an empty stomach. The patients who worry me most are the ones taking ibuprofen daily for chronic pain without eating first. I have seen the gastric consequences of that habit. They are not mild.
💡 Key Takeaway
Ibuprofen and paracetamol can be staggered — alternating every 3 hours — for stronger pain control. Never swallow both at the same time. Always take ibuprofen with food.

When to Use Naproxen Sodium for Body Pain
Naproxen sodium is an NSAID like ibuprofen, but with a longer duration — one dose can last 8 to 12 hours rather than 4 to 6. This makes it practical for people who need sustained relief throughout the day or want to sleep without waking to re-dose.
At OTC doses, naproxen sodium typically comes in 220mg tablets — 220mg every 8 to 12 hours, with a maximum of 440mg in 24 hours. It takes slightly longer to kick in than ibuprofen, so it is not the best choice when you need fast relief from acute pain.
But naproxen carries a slightly higher gastrointestinal irritation risk compared to ibuprofen at equivalent doses. It is not recommended for people over 65 without medical supervision due to increased kidney complication risk. And you must never take naproxen sodium and ibuprofen together — they are both NSAIDs, and combining them multiplies stomach bleeding risk without any additional pain benefit. This is a combination I stop immediately when I see it at the counter.
💡 Key Takeaway
Use naproxen sodium when you need longer-lasting body pain relief and want fewer doses — but never alongside ibuprofen. Take it with food and limit use to the shortest time necessary.
For people whose body pain includes muscle tension or nocturnal cramps, magnesium glycinate supports muscle relaxation and nerve function and is one supplement I regularly recommend:

Myth vs Fact: Common Misconceptions About OTC Body Pain Medicine
❌ Myth
"Paracetamol is always the safest pain medicine, so I can take it as often as I want."
✅ Fact
Paracetamol is safe at correct doses, but exceeding 4g/day — or combining it with alcohol or paracetamol-containing cold medicines — can cause serious liver damage.[1]
❌ Myth
"Taking two NSAIDs together gives stronger pain relief — like ibuprofen AND naproxen."
✅ Fact
Combining two NSAIDs does not improve pain control. It doubles the risk of stomach bleeding, kidney damage, and cardiovascular stress. Never combine them.[2]
❌ Myth
"If OTC medicine isn't working, I should keep increasing the dose until the pain goes away."
✅ Fact
Exceeding OTC dose limits does not improve pain relief but significantly increases harm risk. Pain unresponsive to standard doses needs a medical assessment to find the underlying cause.[3]
💡 Key Takeaway
Paracetamol has a hard liver-safety ceiling. Never combine two NSAIDs. And pain that does not respond to the correct OTC dose deserves investigation — not more medication.

Special Situations: Who Should Not Take NSAIDs
NSAIDs are effective, but they are not for everyone. Patients often do not know what qualifies them for an exception until something goes wrong.
If you have an active stomach ulcer or a history of gastric bleeding, NSAIDs are the wrong choice. They suppress the prostaglandins that protect the stomach lining alongside the ones that cause pain — both effects happen simultaneously. If you must use an NSAID and have a sensitive stomach, your doctor or pharmacist may add omeprazole alongside.
Pregnancy changes the calculation too. NSAIDs are not recommended in the third trimester because they can affect kidney development in the foetus and may delay labour. Paracetamol at the lowest effective dose is the standard recommendation — but always confirm with your doctor or midwife first.
And for chronic kidney disease — even mild — NSAIDs should only be used with medical supervision. They reduce blood flow to the kidneys by around 40% in some people. In a healthy person this resolves quickly. But in someone with reduced kidney reserve it can cause acute kidney injury. Patients frequently ask me about this when they are already on a long course of NSAIDs prescribed elsewhere. My answer is always the same: if you are unsure whether your kidneys are healthy, check before you take a second box. That conversation takes five minutes. A dialysis referral takes years.
💡 Key Takeaway
Avoid NSAIDs with a stomach ulcer, kidney disease, or in the third trimester of pregnancy. Paracetamol is the safer alternative in all three situations — at correct doses.
When Should You Stop OTC Medicine and See a Doctor?
OTC pain medicine is for short-term symptom relief — typically 3 to 5 days for acute pain, 10 days at the outside. Pain that does not improve within this window is telling you something the medicine is covering up rather than fixing.
See a doctor promptly if your body pain comes with fever above 39°C, significant joint swelling with redness and warmth, sudden or severe pain after an injury, pain that wakes you from sleep consistently, or any pain in your chest or abdomen. Also seek assessment if you have been using OTC pain medicine daily for more than two weeks. Long-term daily NSAID use carries documented cardiovascular risks — increased risk of heart attack and stroke at high doses or prolonged use.[4]
If your body pain is primarily in your head, see our dedicated guide on the best OTC medicine for headache. And if the aches are part of a cold or flu, our guide on OTC medicine for cold symptoms covers pain management in that context.
💡 Key Takeaway
Use OTC pain medicines for a maximum of 3 to 10 days for acute body pain. Daily use beyond this warrants a medical review — both for what is causing the pain and for the cumulative effects of the medicine.
🏥 Pharmacist's Verdict
Let me be direct. For most adults with body pain — flu, hard workout, menstrual cramps, general muscle soreness — ibuprofen 400mg taken with food is my first recommendation. It gets to the source of inflammatory pain faster and more effectively than paracetamol, and at OTC doses it is safe for short-term use in healthy adults.
But here is what I tell every patient without exception: check what else you are already taking. Cold and flu tablets, combination painkillers, and even some migraine medicines contain paracetamol. Stack them unknowingly and you are in dangerous territory. The liver does not announce when it is under strain. It just stops working properly.
If your stomach is sensitive or you are on blood thinners, switch to paracetamol and stay on it. And if your body pain has not improved in 5 days with the correct OTC treatment, stop the medication and get assessed. Pain that persists is information. Covering it up indefinitely is not a treatment plan.

Frequently Asked Questions
Ibuprofen 400mg is the best OTC medicine for most body pain because it reduces the inflammation causing pain directly. Paracetamol (500–1000mg) is the safer option if you have a stomach ulcer, take blood thinners, or need something for a child. For longer-lasting relief, naproxen sodium works for 8 to 12 hours per dose.
Yes, but staggered — not simultaneously. They work through different mechanisms, so alternating every 3 hours provides continuous pain coverage. Never swallow both at the same time, and always take ibuprofen with food to protect the stomach lining.
Ibuprofen is generally better for muscle pain because muscle soreness is inflammatory. It reduces prostaglandins at the site of injury. Paracetamol blocks pain signals centrally and is less effective for inflammatory pain — though useful for general aching without a clear inflammatory cause.
Paracetamol is the gentlest OTC pain medicine for the stomach. NSAIDs like ibuprofen and naproxen reduce the protective lining of the stomach as part of their mechanism. If you need an NSAID and have a sensitive stomach, take it with food and ask your pharmacist whether omeprazole is appropriate alongside.
Paracetamol starts working in 30 to 60 minutes and peaks at about 2 hours. Ibuprofen kicks in faster — often 20 to 30 minutes — with peak effect at 1 to 2 hours. Naproxen sodium takes 30 to 60 minutes to begin but lasts 8 to 12 hours. For fastest relief, ibuprofen wins. For sustained relief without re-dosing, naproxen sodium wins.
See a doctor if body pain lasts more than 10 days without improvement, is severe or sudden, follows an injury with visible swelling or restricted movement, comes with fever above 39°C, involves the chest or abdomen, or if you are pregnant, have kidney disease, liver disease, or take prescription blood thinners. Daily OTC use beyond 2 weeks also warrants a medical review.
