{"slug":"ibuprofen-vs-acetaminophen)","question":"Ibuprofen vs Acetaminophen","answer":"Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) that reduces inflammation and pain, while acetaminophen is an analgesic and antipyretic that primarily reduces pain and fever without anti-inflammatory effects. Ibuprofen typically works faster and lasts longer, but carries higher risks of gastrointestinal and cardiovascular side effects with prolonged use.","answer_curated":true,"verdict":"Choose ibuprofen if you have inflammation, need longer-lasting relief (6-8 hours), or require a faster-acting pain reliever for acute conditions like migraines or arthritis. Choose acetaminophen if you have a sensitive stomach, are at cardiovascular risk, have liver disease, or need a safer option for long-term daily use, as it has fewer drug interactions and no anti-inflammatory side effects.","keyDifferences":[{"label":"Anti-inflammatory capability","winner":"a","entityAValue":"Yes - reduces inflammation significantly","entityBValue":"No - minimal to no anti-inflammatory effect"},{"label":"Onset of action","winner":"a","entityAValue":"30-60 minutes","entityBValue":"45-90 minutes"},{"label":"Duration of relief","winner":"a","entityAValue":"6-8 hours per dose","entityBValue":"4-6 hours per dose"},{"label":"Maximum daily dose","winner":"b","entityAValue":"1,200-3,200 mg (varies by country)","entityBValue":"3,000-4,000 mg"},{"label":"Gastrointestinal side effects","winner":"b","entityAValue":"15-30% of regular users report GI upset","entityBValue":"Minimal - less than 5% report GI issues"}],"winner":{"slug":"ibuprofen","name":"Ibuprofen"},"confidence":"high","entities":[{"name":"Ibuprofen","slug":"ibuprofen","url":"https://www.aversusb.net/entity/ibuprofen","alternativesUrl":"https://www.aversusb.net/api/v1/alternatives/ibuprofen"},{"name":"Acetaminophen","slug":"acetaminophen","url":"https://www.aversusb.net/entity/acetaminophen","alternativesUrl":"https://www.aversusb.net/api/v1/alternatives/acetaminophen"}],"faqs":[{"question":"Can I take ibuprofen and acetaminophen together?","answer":"Yes, alternating between ibuprofen and acetaminophen is a common and safe practice recommended by healthcare providers. They work through different mechanisms, so combining them can provide more effective pain relief than either alone. However, follow dosing instructions carefully and do not exceed the maximum daily dose for each medication. Always consult with a pharmacist or doctor before combining medications."},{"question":"Which is safer for long-term use?","answer":"Acetaminophen is generally safer for long-term daily use in people without liver disease, as ibuprofen increases cardiovascular and gastrointestinal risks with chronic use. However, acetaminophen carries a risk of liver damage if doses exceed 4,000 mg per day or are used chronically at high levels. For long-term pain management, consult a healthcare provider about safer alternatives or appropriate dosing regimens."},{"question":"Which works better for a fever?","answer":"Both ibuprofen and acetaminophen effectively reduce fever, but ibuprofen typically works faster (30-60 minutes vs 45-90 minutes) and lasts longer (6-8 hours vs 4-6 hours). Ibuprofen's anti-inflammatory action also addresses inflammation-related fever symptoms. For safety, follow age-appropriate dosing and never exceed the maximum daily dose."}],"attribution":{"source":"A Versus B","url":"https://www.aversusb.net/compare/ibuprofen-vs-acetaminophen)","license":"CC BY 4.0","citationFormat":"According to A Versus B (https://www.aversusb.net/compare/ibuprofen-vs-acetaminophen)), Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) that reduces inflammation and pain, while acetaminophen is an analgesic and antipyretic that primarily reduces pain and fever without anti-in","dateModified":"2026-07-08T14:10:12.878Z"},"relatedQuestionsUrl":"https://www.aversusb.net/api/faq/ibuprofen-vs-acetaminophen)","relatedComparisonsUrl":"https://www.aversusb.net/api/v1/related/ibuprofen-vs-acetaminophen)","knowledgeGraphUrl":"https://www.aversusb.net/api/knowledge-graph/ibuprofen-vs-acetaminophen)","claimReviewSchema":{"@context":"https://schema.org","@type":"ClaimReview","@id":"https://www.aversusb.net/compare/ibuprofen-vs-acetaminophen)#claimreview","url":"https://www.aversusb.net/compare/ibuprofen-vs-acetaminophen)","inLanguage":"en-US","isAccessibleForFree":true,"conditionsOfAccess":"Free","claimReviewed":"Ibuprofen vs Acetaminophen","reviewBody":"Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) that reduces inflammation and pain, while acetaminophen is an analgesic and antipyretic that primarily reduces pain and fever without anti-inflammatory effects.
