200-400 mg orally every 4-6 hours as needed; maximum 1200 mg/day without prescription.
2-4 hours (terminal half-life). Short half-life requires frequent dosing for sustained analgesic/antipyretic effect.
2-4 hours (terminal elimination half-life); in overdose or hepatic impairment, may be prolonged to >4 hours. Clinically, the short half-life supports dosing every 6-8 hours for acute pain.
Hepatic metabolism primarily via CYP2C9.
Primarily hepatic via CYP2C9; also undergoes glucuronidation. Metabolites include hydroxy- and carboxy-ibuprofen, which are inactive.
Renal: 90% as metabolites (glucuronides, hydroxylated derivatives), <10% unchanged. Fecal: <5%.
Renal excretion of conjugated metabolites (approximately 90% of an administered dose) with less than 1% excreted unchanged. Biliary/fecal elimination accounts for less than 5%.
99% bound to albumin.
Approximately 99% bound to albumin.
0.1-0.2 L/kg (low Vd, confined to plasma and interstitial fluid).
0.1-0.3 L/kg. The low Vd indicates limited tissue distribution, primarily confined to plasma and extracellular fluid.
Oral: 80-100% (with food may reduce rate).
Oral: 80-100% (well absorbed). Topical: approximately 5-10% systemically absorbed (varies with formulation and application site).
e GFR 30-59 m L/min: reduce dose by 50% or increase interval to every 8-12 hours; e GFR <30 m L/min: avoid use or maximum 400 mg/day.
Cr Cl 30-60 m L/min: reduce dose by 50% and avoid in Cr Cl <30 m L/min.
Child-Pugh A: no adjustment; Child-Pugh B: reduce dose by 50%; Child-Pugh C: avoid use.
Child-Pugh A: no adjustment; Child-Pugh B: reduce dose by 50%; Child-Pugh C: contraindicated.
6 months to 12 years: 5-10 mg/kg/dose orally every 6-8 hours; maximum 40 mg/kg/day. For fever or pain: 5 mg/kg per dose for temperatures <102.5°F, 10 mg/kg per dose for higher fever.
5-10 mg/kg/dose orally every 6-8 hours; maximum 40 mg/kg/day.
Start at lowest effective dose (200 mg every 6-8 hours); maximum 400 mg/day due to increased risk of renal and GI adverse effects.
Initiate at lowest effective dose (e.g., 200 mg every 8-12 hours); monitor renal function and avoid long-term use.
Nonsteroidal anti-inflammatory drugs (NSAIDs) cause an increased risk of serious cardiovascular thrombotic events, including myocardial infarction and stroke, which can be fatal. This risk may increase with duration of use. Patients with cardiovascular disease or risk factors may be at greater risk.
NSAIDs increase the risk of serious cardiovascular thrombotic events, myocardial infarction, and stroke, which can be fatal. Risk increases with duration of use. Patients with cardiovascular disease or risk factors may be at greater risk. NSAIDs are contraindicated for treatment of perioperative pain in the setting of coronary artery bypass graft (CABG) surgery.
Cardiovascular risk, gastrointestinal bleeding, renal toxicity, hypertension, anaphylactoid reactions, hepatic effects, asthma exacerbation, pregnancy avoidance (third trimester).
Risk of serious GI adverse events including bleeding, ulceration, and perforation; NSAIDs should be used with caution in patients with history of peptic ulcer disease or GI bleeding. May cause renal toxicity, especially in patients with pre-existing renal impairment. Use with caution in patients with asthma, congestive heart failure, or hypertension.
Hypersensitivity to ibuprofen or NSAIDs, history of asthma, urticaria, or allergic-type reactions after taking aspirin or other NSAIDs, perioperative pain in the setting of coronary artery bypass graft (CABG) surgery, severe renal impairment, active peptic ulcer disease.
History of hypersensitivity to ibuprofen or any other NSAID; active peptic ulcer disease or GI bleeding; severe renal impairment; history of serious cardiovascular event; perioperative pain in CABG surgery; third trimester of pregnancy.
Avoid alcohol. Take with food or milk to minimize gastric irritation. Grapefruit juice may modestly increase ibuprofen absorption but clinical significance is low; no strict restriction. Administer with a full glass of water.
Alcohol may increase risk of GI bleeding. Food delays absorption but does not significantly affect total exposure; take with food to improve tolerability.
First trimester: Avoid due to potential increased risk of miscarriage and congenital malformations (cardiac defects, gastroschisis). Second trimester: Use only if clearly needed; no clear teratogenic risk but may cause premature closure of ductus arteriosus. Third trimester: Contraindicated due to risk of premature ductus arteriosus closure, oligohydramnios, and neonatal renal impairment.
First trimester: Association with increased risk of miscarriage and congenital cardiac defects (odds ratio 1.86). Second/third trimester: Premature closure of ductus arteriosus, oligohydramnios, fetal renal impairment; avoid after 30 weeks gestation. Use not recommended during pregnancy.
Ibuprofen is excreted into breast milk in very low amounts (M/P ratio approximately 0.01). Considered compatible with breastfeeding; use lowest effective dose for shortest duration. Monitor infant for rash, gastrointestinal effects, or drowsiness.
Excreted in breast milk in low concentrations (M/P ratio <0.02). American Academy of Pediatrics considers compatible with breastfeeding. Monitor infant for gastrointestinal distress or rash. Use lowest effective dose for shortest duration.
No specific dose adjustment recommended for pregnancy-related pharmacokinetic changes. However, due to increased plasma volume and renal clearance, therapeutic efficacy may be reduced; use lowest effective dose. Avoid in third trimester.
Increased clearance and volume of distribution in pregnancy (especially third trimester) may require dose escalation to maintain efficacy. However, due to fetal risks, avoid use; if necessary, use minimal effective dose for shortest duration.
Ibuprofen (IBU-TAB 200) is an NSAID; avoid in patients with Cr Cl <30 m L/min. Dose adjustment not needed for mild hepatic impairment but contraindicated in severe hepatic disease. Use lowest effective dose for shortest duration to minimize renal and GI risk. Can mask signs of infection; monitor for fever in at-risk patients. Not recommended in late pregnancy (after 30 weeks) due to risk of premature ductus arteriosus closure.
IBU-TAB (ibuprofen) is a non-selective COX inhibitor; use lowest effective dose for shortest duration to minimize GI and renal risks. Avoid in patients with NSAID-sensitive asthma, severe renal impairment (e GFR <30 m L/min), or perioperative pain in CABG surgery. Concomitant aspirin antagonizes irreversible antiplatelet effect; separate by 2 hours if immediate-release. Monitor for fluid retention and hypertension in cardiac patients.
