e GFR 30-59 m L/min: No adjustment; e GFR 15-29 m L/min: Reduce dose to 200 mg every 6-8 hours, maximum 600 mg/day; e GFR <15 m L/min: Avoid use.
GFR 30-59 m L/min: use minimum effective dose, monitor renal function; GFR <30 m L/min: avoid use; dialysis: not removed by hemodialysis, avoid use.
Child-Pugh Class A: No adjustment; Child-Pugh Class B: Use with caution, reduce dose by 50%; Child-Pugh Class C: Avoid use.
Child-Pugh Class A: no adjustment; Class B: use with caution, reduce dose by 50%; Class C: avoid use.
Children weighing ≥50 kg: Same as adult; <50 kg: 7.5-10 mg/kg per dose every 6-8 hours, maximum 30 mg/kg/day.
Children 6 months to 12 years: 5-10 mg/kg/dose every 6-8 hours; maximum 40 mg/kg/day, not to exceed adult maximum; for fever >39°C, 10 mg/kg/dose; available as oral suspension (100 mg/5 m L).
Start at lowest effective dose (200 mg every 6-8 hours), monitor renal function and gastrointestinal bleeding risk; maximum 600 mg/day.
Initiate at the lowest effective dose (e.g., 200-400 mg every 6-8 hours), maximum 3200 mg/day; monitor for GI bleeding and renal impairment; avoid prolonged use due to increased cardiovascular and GI risks.
Nonsteroidal anti-inflammatory drugs (NSAIDs) cause an increased risk of serious gastrointestinal adverse events including bleeding, ulceration, and perforation of the stomach or intestines, which can be fatal. These events can occur at any time without warning symptoms. Elderly patients and those with a prior history of peptic ulcer disease or GI bleeding are at greater risk.
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 occur early in treatment and may increase with duration of use. Contraindicated for treatment of perioperative pain in the setting of coronary artery bypass graft (CABG) surgery.
Increased risk of serious cardiovascular thrombotic events, myocardial infarction, and stroke; risk of serious GI adverse events; avoid in setting of coronary artery bypass graft (CABG) surgery; renal toxicity; anaphylactoid reactions; severe skin reactions (e.g., Stevens-Johnson syndrome); may blunt the antihypertensive effect of ACE inhibitors; avoid late pregnancy due to risk of premature closure of ductus arteriosus.
Increased risk of cardiovascular thrombotic events; risk of serious GI adverse events including bleeding, ulceration, and perforation; renal toxicity; hypertension; anaphylactoid reactions; serious skin reactions; hematologic toxicity; avoid in advanced renal disease.
Known hypersensitivity to ibuprofen or any component of the formulation; history of asthma, urticaria, or other allergic-type reactions after taking aspirin or other NSAIDs; perioperative pain in the setting of coronary artery bypass graft (CABG) surgery; late pregnancy (third trimester).
Hypersensitivity to ibuprofen or other NSAIDs; history of asthma, urticaria, or allergic-type reactions after taking aspirin or other NSAIDs; perioperative pain in CABG surgery; active GI bleeding; history of recurrent peptic ulcer disease; severe heart failure.
Avoid alcohol and caffeine-containing foods/drinks (coffee, tea, cola, chocolate) due to additive caffeine effects. Grapefruit juice may increase ibuprofen absorption; consider avoidance. No other significant dietary restrictions.
Concurrent alcohol consumption increases risk of GI bleeding and ulceration. Avoid high-sodium foods to minimize fluid retention and potential exacerbation of hypertension. Grapefruit juice may slightly reduce rate of absorption but is not clinically significant.
First trimester: Risk of spontaneous abortion and congenital malformations (cardiac, gastroschisis). Second trimester: Avoid due to possible oligohydramnios and fetal renal impairment. Third trimester: Contraindicated after 30 weeks gestation due to risk of premature closure of ductus arteriosus and persistent pulmonary hypertension. NSAID use after 20 weeks may cause oligohydramnios from fetal renal dysfunction.
Motrin (ibuprofen) is an NSAID. First trimester: Risk of miscarriage and congenital malformations, particularly cardiac defects, with use. Second trimester: Generally considered safer but avoid prolonged use due to potential for oligohydramnios. Third trimester: Contraindicated after 20 weeks due to risk of premature ductus arteriosus closure, oligohydramnios, and neonatal complications including pulmonary hypertension and renal impairment.
Ibuprofen is excreted into breast milk in low amounts (M/P ratio approximately 0.6-1.0). Peak infant dose is less than 1% of maternal weight-adjusted dose. Considered compatible with breastfeeding; use lowest effective dose for shortest duration.
Ibuprofen is excreted into breast milk in very small amounts. The M/P ratio is approximately 0.01. The relative infant dose is less than 1% of maternal weight-adjusted dose. Considered compatible with breastfeeding, but avoid high doses or prolonged use.
No standard pharmacokinetic data mandating dose adjustment in pregnancy. However, increased renal clearance and volume of distribution may require higher doses for efficacy; use lowest effective dose and avoid third trimester. No specific dosage adjustment recommended in product labeling.
No dose adjustment is recommended in pregnancy; however, use should be restricted to the lowest effective dose for the shortest duration possible. Pharmacokinetic changes in pregnancy (increased volume of distribution, renal clearance) may reduce plasma concentrations, but no formal dose adjustment studies exist. Avoid use after 20 weeks gestation.
Motrin Migraine Pain contains ibuprofen 200 mg and caffeine 65 mg per tablet. Caffeine enhances analgesic effect and may help with migraine-associated fatigue. Absorb more rapidly on empty stomach; take at first sign of migraine. Avoid in patients with aspirin allergy, peptic ulcer disease, or uncontrolled hypertension.
For acute pain, use lowest effective dose for shortest duration to minimize GI and renal risks. Administer with food or milk to reduce GI irritation. Avoid in patients with severe renal impairment (Cr Cl <30 m L/min) or active peptic ulcer disease. Ibuprofen can mask fever, making infection detection difficult. Caution in asthma patients as it may precipitate bronchospasm. Monitor blood pressure in hypertensive patients due to potential for fluid retention.
