Cyclooxygenase (COX-1 and COX-2) inhibitor, reducing prostaglandin synthesis.
Naproxen, a nonsteroidal anti-inflammatory drug (NSAID), inhibits cyclooxygenase (COX-1 and COX-2) enzymes, thereby reducing prostaglandin synthesis. This leads to decreased inflammation, pain, and fever.

200-400 mg orally every 4-6 hours as needed; maximum 1200 mg/day for nonprescription use.
220 mg orally every 8 to 12 hours as needed; maximum 660 mg per day.
2-4 hours (terminal half-life). Short half-life requires frequent dosing for sustained analgesic/antipyretic effect.
Terminal elimination half-life is 12-17 hours; allows twice-daily dosing for steady-state concentrations.
Hepatic metabolism primarily via CYP2C9.
Naproxen is extensively metabolized in the liver primarily via CYP2C9 to 6-O-desmethyl naproxen, and less than 5% is excreted unchanged in urine.
Renal: 90% as metabolites (glucuronides, hydroxylated derivatives), <10% unchanged. Fecal: <5%.
Renal (95% as unchanged drug and metabolites); biliary/fecal (5%)

Oral: ~95%; immediate-release formulation.
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.
GFR 30-59 m L/min: reduce dose and avoid long-term use; GFR <30 m L/min: contraindicated.
Child-Pugh A: no adjustment; Child-Pugh B: reduce dose by 50%; Child-Pugh C: avoid use.

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.
2-12 years: 2.5-5 mg/kg/dose orally every 8-12 hours; maximum 10 mg/kg/day. 12 years and older: same as adult.
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 (220 mg every 12 hours); maximum 440 mg per day; monitor renal function and GI bleeding 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 increase with duration of use. Patients with cardiovascular disease or risk factors may be 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 increase with duration of use. Patients with cardiovascular disease or risk factors may be at greater risk. Naproxen is contraindicated for treatment of peri-operative pain in the setting of coronary artery bypass graft (CABG) surgery. 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 during use and without warning symptoms. Elderly patients and patients with a prior history of peptic ulcer disease or GI bleeding are at greater risk.

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.
Avoid concurrent use of alcohol as it increases GI bleeding risk. No specific food restrictions; taking with food or milk may reduce dyspepsia. High potassium foods (e.g., bananas, spinach) may increase hyperkalemia risk in patients with renal impairment.
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: Risk of spontaneous abortion and cardiac defects (odds ratio 1.86 for NSAIDs). Second trimester: Possible fetal renal dysfunction and oligohydramnios; ductus arteriosus premature closure risk begins. Third trimester: High risk of premature closure of ductus arteriosus, oligohydramnios, necrotizing enterocolitis, intracranial hemorrhage, and renal impairment; avoid after 30 weeks.
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 ~0.12); relative infant dose <1% of maternal weight-adjusted dose. Compatible with breastfeeding; monitor infant for potential adverse effects (gastrointestinal upset, rash) at higher doses.
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.
No specific pharmacokinetic-based dose adjustments; however, use lowest effective dose for shortest duration, especially after 20 weeks. Avoid use after 30 weeks gestation due to fetal risks. Increased volume of distribution may reduce serum concentrations but no dose adjustment recommended.
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.
ALEVE (naproxen sodium) is a nonsteroidal anti-inflammatory drug (NSAID) with a longer half-life (12-17 hours) allowing twice-daily dosing. It carries a boxed warning for cardiovascular and gastrointestinal risk. Use lowest effective dose for shortest duration. Contraindicated in patients with aspirin allergy, perioperative pain in CABG surgery, and significant renal impairment. Monitor renal function in elderly, volume-depleted patients, and those on ACE inhibitors or diuretics.

Common clinical questions about IBU-TAB 200 vs ALEVE, answered by our medical review team.
IBU-TAB 200 is a Nonsteroidal Anti-inflammatory Drug (NSAID) that works by Cyclooxygenase (COX-1 and COX-2) inhibitor, reducing prostaglandin synthesis.. ALEVE is a Nonsteroidal Anti-inflammatory Drug (NSAID) that works by Naproxen, a nonsteroidal anti-inflammatory drug (NSAID), inhibits cyclooxygenase (COX-1 and COX-2) enzymes, thereby reducing prostaglandin synthesis. This leads to decreased inflammation, pain, and fever.. They differ in pharmacokinetic profiles, FDA-approved indications, and side effect profiles.
Potency comparisons between IBU-TAB 200 and ALEVE depend on the specific clinical indication. These are both Nonsteroidal Anti-inflammatory Drug (NSAID) agents and are not directly interchangeable by dose. A physician or clinical pharmacist should guide any therapeutic switching decisions.
The standard adult dose of IBU-TAB 200 is: 200-400 mg orally every 4-6 hours as needed; maximum 1200 mg/day for nonprescription use.. The standard adult dose of ALEVE is: 220 mg orally every 8 to 12 hours as needed; maximum 660 mg per day.. Dosing should always be individualized based on indication, renal and hepatic function, age, and other patient factors.
No direct drug-drug interaction has been formally documented between IBU-TAB 200 and ALEVE in current clinical databases. However, individual patient risk factors including other medications, organ function, and comorbidities should always be evaluated by a qualified healthcare provider.
The maternal-fetal safety profiles differ. IBU-TAB 200 is classified as Category C. First trimester: Avoid due to potential increased risk of miscarriage and congenital malformations (cardiac defects, gastroschisis). Second trimester: Use only if clearly needed; n. ALEVE is classified as Category C. First trimester: Risk of spontaneous abortion and cardiac defects (odds ratio 1.86 for NSAIDs).
