Walk the OTC pain aisle at any US pharmacy and three bottles dominate the shelf: blue Aleve, orange-red ibuprofen, and red-and-white Tylenol. The Aleve vs ibuprofen vs Tylenol comparison confuses most shoppers because the first two are NSAIDs with the same basic mechanism and the third is a completely different drug class. For more on common OTC medications, see our medical conditions guide. Fast verdict: Aleve (naproxen) lasts longest per dose, ibuprofen acts faster and is easier to dose short-term, and Tylenol (acetaminophen) is the safest everyday choice for non-inflammatory pain and for people who can’t take NSAIDs.
Quick Comparison Overview
Aleve is the brand name for naproxen sodium, an NSAID typically dosed at 220 mg per tablet OTC. Ibuprofen (Advil, Motrin) is another NSAID sold in 200 mg OTC tablets. Tylenol is the brand name for acetaminophen, a central-acting analgesic and fever reducer, sold in 325, 500, and 650 mg forms. All three are OTC, generic-cheap, and effective for everyday aches.
How Each Drug Works
Aleve and ibuprofen both inhibit COX-1 and COX-2 enzymes, blocking prostaglandin production throughout the body. They reduce pain, fever, and inflammation in essentially the same way; the main differences are duration and tissue accumulation. Naproxen has a longer half-life (12 to 17 hours) than ibuprofen (2 to 4 hours), which is why Aleve is dosed twice daily while ibuprofen is dosed every 4 to 6 hours.
Tylenol works differently. According to the NIH StatPearls monograph, acetaminophen acts centrally through COX inhibition and serotonergic/endocannabinoid pathways. It reduces pain and fever but does not meaningfully reduce inflammation at injury sites.
Effectiveness Research
For acute inflammatory pain (dental, menstrual, musculoskeletal), both Aleve and ibuprofen outperform acetaminophen in randomized trials. A Cochrane analysis of single-dose postoperative pain found ibuprofen 400 mg gave at least 50 percent pain relief to 54 percent of patients; naproxen 500 mg gave it to 52 percent; acetaminophen 1000 mg gave it to 46 percent. The differences are small but real, and most matter when inflammation is driving pain.
For fever and tension headaches, all three drugs work similarly. For osteoarthritis, naproxen is often preferred over ibuprofen because its longer duration gives smoother symptom control with fewer daily doses.
Side Effects Compared
Aleve and ibuprofen share the NSAID profile: heartburn, dyspepsia, ulcer risk, GI bleeding, kidney strain, and cardiovascular risk with long-term use. Naproxen’s longer half-life means slightly higher GI and kidney strain per day of use. However, among non-aspirin NSAIDs, naproxen has the most favorable cardiovascular safety data. A Lancet meta-analysis of NSAID trials found naproxen did not significantly increase cardiovascular events, unlike ibuprofen and diclofenac at high doses.
Tylenol has the cleanest everyday profile: no GI, renal, or cardiovascular risks at standard doses. Its main concern is liver toxicity in overdose (single doses over 150 mg/kg or chronic intake above 4,000 mg/day) and in people who drink heavily.
Dosing Side-by-Side
Aleve OTC: 220 mg every 8 to 12 hours, max 660 mg per day for adults over 65 and 880 mg per day for adults under 65 (package directions). Take with food to reduce GI upset.
Ibuprofen OTC: 200 to 400 mg every 4 to 6 hours, max 1,200 mg per day. Take with food.
Tylenol: 325 to 1,000 mg every 4 to 6 hours, max 3,000 to 4,000 mg per day. Food doesn’t affect absorption. Watch hidden acetaminophen in cold and flu combos and in prescription opioid combinations.
Which Is Better for Specific Situations
Period cramps or dental pain: either Aleve or ibuprofen will outperform Tylenol; pick whichever you prefer for duration. Arthritis flare: Aleve’s longer action is convenient. Acute muscle strain: ibuprofen’s faster onset is handy.
Fever alone or tension headache: Tylenol is a fine choice and cleaner on the body. Pregnancy: Tylenol is preferred; avoid NSAIDs especially in the third trimester per ACOG. Blood thinner use, active ulcer, CKD, or severe hypertension: Tylenol is the safer choice. Cardiovascular disease: if an NSAID is needed, naproxen has slightly better cardiovascular safety data than ibuprofen.
Cost and Availability
All three are OTC and inexpensive. Generic naproxen sodium 220 mg runs about $6 to $12 for 100 tablets. Generic ibuprofen 200 mg is $5 to $10 for 100. Generic acetaminophen is $5 to $10 for 100. Brand names cost 2 to 4 times more for identical active ingredients.
Interactions and Warnings
Aleve and ibuprofen interact with the same drugs: ACE inhibitors, ARBs, diuretics, lithium, methotrexate, SSRIs, warfarin, and low-dose aspirin (NSAIDs can reduce cardioprotective effect). Tylenol interacts with warfarin at sustained high doses and is risky with heavy alcohol use. Do not combine multiple acetaminophen-containing products.

Frequently Asked Questions
Is Aleve stronger than ibuprofen?
Not really. Both are NSAIDs with similar effectiveness per dose. Aleve lasts longer per dose (8 to 12 hours versus 4 to 6), which can feel like “stronger” because the pain doesn’t return as quickly.
Can I take Aleve and Tylenol together?
Yes. They work by different mechanisms and can be combined. Do not combine Aleve with ibuprofen — both are NSAIDs and stacking them increases GI and kidney risk without added benefit.
Which is safest for daily use?
Tylenol is the gentlest for most adults at standard doses, as long as you stay under 3,000 mg/day and avoid heavy drinking. NSAIDs carry real risks with regular long-term use.
Which works best for arthritis?
Aleve (naproxen) is often preferred for osteoarthritis because its longer duration gives smoother symptom control with fewer daily doses. Consult a clinician before using NSAIDs daily for more than 1 to 2 weeks.
The Bottom Line
Aleve vs ibuprofen vs Tylenol comes down to three buckets. Aleve is the long-acting NSAID for all-day inflammatory pain. Ibuprofen is the fast-acting NSAID for short-term flares. Tylenol is the safer choice for everyday mild pain, fever, pregnancy, and any situation where NSAIDs are risky. Match the drug to the problem and to your own health history, and never stack two NSAIDs or two acetaminophen products at once.
