Last clinically reviewed: July 2026 · OpiCalc Medical Review Team
Hydrocodone is a semisynthetic opioid agonist with selectivity for mu-opioid receptors, producing analgesia and sedation. Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX-1 and COX-2), reducing prostaglandin synthesis, thereby providing anti-inflammatory, analgesic, and antipyretic effects.
Irreversibly acetylates cyclooxygenase-1 (COX-1) and cyclooxygenase-2 (COX-2), inhibiting prostaglandin and thromboxane A2 synthesis, leading to analgesic, antipyretic, anti-inflammatory, and antiplatelet effects.
Short-term (up to 10 days) management of acute pain severe enough to require an opioid analgesic and for which alternative treatments are inadequate
Relief of pain, fever, and inflammation,Reduction of risk of myocardial infarction in patients with previous MI or unstable angina,Prevention of recurrent ischemic stroke or transient ischemic attack
One tablet (hydrocodone bitartrate 5 mg/ibuprofen 200 mg) orally every 4 to 6 hours as needed for pain; maximum 5 tablets per day.
325-650 mg every 8 hours for pain/fever; 81-325 mg daily for cardiovascular prophylaxis.
Hydrocodone: 3.8-4.5 hours (immediate release); Ibuprofen: 1.8-2.5 hours (racemic, S-enantiomer slightly shorter). Clinical context: dosing every 4-6 hours due to hydrocodone half-life.
15-20 hours (terminal elimination half-life) for salicylate at therapeutic concentrations; prolonged to 20-30 hours at high doses due to saturation of hepatic metabolism (zero-order kinetics).
Hydrocodone is primarily metabolized by CYP3A4 and CYP2D6 enzymes to hydromorphone (active) and norhydrocodone (inactive). Ibuprofen is metabolized by CYP2C9 to inactive metabolites (hydroxyibuprofen and carboxyibuprofen).
Hepatic hydrolysis by esterases to salicylic acid, which is primarily conjugated in the liver via glucuronidation and glycine conjugation (salicyluric acid), with minor oxidation by cytochrome P450 (CYP2C9) to gentisic acid.
Hydrocodone: primarily renal (60-70% as metabolites, <12% unchanged); Ibuprofen: primarily renal (90% as metabolites and conjugates, <1% unchanged), minor biliary/fecal.
Renal excretion of conjugated salicylate metabolites (75% as salicyluric acid, 10% as salicyl phenolic glucuronide, 5% as salicyl acyl glucuronide, 5% as gentisic acid); 10% free salicylate; approximately 10% eliminated in feces via bile.
Hydrocodone: ~19% bound to plasma proteins; Ibuprofen: >99% bound to albumin.
80-90% bound to albumin; binding is concentration-dependent and saturable.
Hydrocodone: 3.3-4.7 L/kg; Ibuprofen: 0.1-0.2 L/kg. High Vd for hydrocodone indicates extensive tissue distribution; low Vd for ibuprofen indicates plasma and interstitial fluid confinement.
0.15-0.2 L/kg for salicylate; distributes into synovial fluid, CNS, and placental tissues; Vd increases in acidosis.
Hydrocodone: mean absolute bioavailability ~70-80% (oral); Ibuprofen: ~80-100% (oral, rapid absorption).
Oral: Approximately 100% for immediate-release, but extended-release may have slightly reduced absorption (relative bioavailability 85-90% compared to immediate-release).
GFR 30-60 m L/min: Use with caution, consider reducing dose or increasing interval. GFR <30 m L/min: Not recommended due to accumulation of ibuprofen and hydrocodone metabolites.
Avoid in severe renal impairment (Cr Cl <30 m L/min). Use with caution and monitor for bleeding in moderate impairment. Reduce dose or extend interval.
Child-Pugh Class B: Start with lowest possible dose, monitor closely. Child-Pugh Class C: Contraindicated due to risk of toxicity.
Avoid in severe hepatic impairment. Use with caution in moderate impairment; monitor liver function.
Not recommended for use in pediatric patients; safety and efficacy not established.
Not recommended in children <12 years for viral infections due to Reye's syndrome risk (contraindicated).
Initiate with lowest effective dose (e.g., half tablet) and monitor for CNS and respiratory depression; reduce maximum daily dose to 4 tablets due to increased sensitivity and renal impairment.
Increased risk of GI bleeding and renal impairment; use lowest effective dose, monitor renal function and signs of bleeding.
Risk of addiction, abuse, and misuse; life-threatening respiratory depression; accidental ingestion (especially in children) can be fatal; neonatal opioid withdrawal syndrome with prolonged use during pregnancy; risks from concomitant use with benzodiazepines or other CNS depressants; hepatotoxicity from ibuprofen (NSAIDs cause an increased risk of serious gastrointestinal adverse events including bleeding, ulceration, and perforation, which can be fatal).

Grapefruit and grapefruit juice may increase hydrocodone levels and risk of adverse effects; avoid concurrent use. Alcohol potentiates CNS depression and increases GI bleeding risk; avoid altogether. High-fat meals may delay absorption of hydrocodone, but clinical impact is minimal; take consistently with or without food.
Avoid alcohol; may increase risk of gastrointestinal bleeding. No specific food restrictions, but taking with food can reduce gastric irritation. Avoid high-dose vitamin C supplements as they may increase salicylate levels.
Pregnancy Category C: No adequate studies in pregnant women. Ibuprofen (NSAID) is associated with increased risk of premature closure of ductus arteriosus and oligohydramnios in third trimester; avoid after 30 weeks gestation. Hydrocodone may cause respiratory depression in neonate if used near term; chronic use may lead to neonatal opioid withdrawal syndrome. First trimester: limited data, but NSAIDs may increase risk of miscarriage; hydrocodone not associated with major malformations. Second trimester: generally considered safer, but risks remain. Third trimester: avoid NSAIDs; hydrocodone use only if benefit outweighs risk.
First trimester: No well-controlled studies. Avoid use unless clearly needed. Second and third trimesters: Aspirin should be avoided due to risk of premature closure of ductus arteriosus, oligohydramnios, and increased risk of maternal and fetal bleeding. High doses may cause constriction of ductus arteriosus in utero and persistent pulmonary hypertension in newborn.
Limited data; both drugs excreted into breast milk. Ibuprofen M/P ratio ~0.01, considered compatible. Hydrocodone M/P ratio ~2.0; low levels in milk but risk of infant sedation and respiratory depression. Use caution; monitor infant for drowsiness, difficulty breastfeeding. American Academy of Pediatrics considers hydrocodone as 'usually compatible' but avoid when possible. Alternatives preferred.
Small amounts of aspirin are excreted in breast milk. M/P ratio not established. Use with caution in breastfeeding women; avoid high doses due to risk of Reye's syndrome in infants and potential for adverse effects on platelet function.
No specific pharmacokinetic studies; however, pregnancy increases clearance and volume of distribution for both drugs. Ibuprofen: dose adjustments not typically recommended, but due to renal effects and fetal risks, use lowest effective dose for shortest duration. Hydrocodone: increased clearance may require higher doses to achieve analgesic effect; consider patient-specific titration. However, due to neonatal risks, minimize use and duration.
Pregnancy increases clearance of aspirin; however, dose adjustments are not routinely recommended due to narrow therapeutic index. Use lowest effective dose for shortest duration. Avoid in third trimester.
Hydrocodone/ibuprofen combines an opioid agonist with an NSAID. Be aware of additive risks: respiratory depression, sedation, GI bleeding, renal impairment, and cardiovascular thrombotic events. Avoid in patients with severe asthma, GI obstruction, or after recent bariatric surgery. Use lowest effective dose for shortest duration. Monitor for serotonin syndrome if used with other serotonergic drugs. Abrupt discontinuation after prolonged use may cause withdrawal.
8-Hour Bayer is enteric-coated aspirin designed for extended release, reducing gastrointestinal irritation. Onset of action is delayed; not suitable for acute pain or rapid antiplatelet effect. Use with caution in patients with history of peptic ulcer disease or on anticoagulants. Monitor renal function in elderly or dehydrated patients. Avoid in children with viral illness due to Reye's syndrome risk.
Take exactly as prescribed; do not increase dose or frequency without consulting your doctor.,Hydrocodone can cause drowsiness; avoid driving or operating heavy machinery until you know how it affects you.,Do not consume alcohol or other CNS depressants (e.g., benzodiazepines, other opioids) while taking this medication.,Ibuprofen may increase risk of stomach bleeding; report black/tarry stools, coffee-ground vomit, or abdominal pain.,Avoid other NSAIDs (e.g., aspirin, naproxen) or COX-2 inhibitors to prevent additive GI and renal toxicity.,Store securely away from children and others; dispose of unused medication via take-back programs.,Do not abruptly stop after long-term use; withdrawal symptoms may occur (anxiety, sweating, nausea).
Take with a full glass of water; do not crush or chew the tablet.,Do not use within 7 days before surgery due to bleeding risk.,If used for pain, consult a doctor if symptoms persist for more than 10 days.,Avoid alcohol while taking this medication to reduce stomach bleeding risk.,Seek medical attention for signs of bleeding (black stools, blood in vomit).
"Concomitant use of Ibuprofen (a nonsteroidal anti-inflammatory drug, NSAID) and Methylprednisolone (a systemic corticosteroid) synergistically increases the risk of gastrointestinal (GI) ulceration, bleeding, and perforation due to additive inhibition of prostaglandin synthesis and mucosal protection. Additionally, Ibuprofen may potentiate the immunosuppressive effects of Methylprednisolone, elevating infection risk. This interaction can lead to serious clinical outcomes, including acute GI hemorrhage, perforation, and impaired wound healing."
"The combination of olopatadine, an antihistamine with sedative properties, and ibuprofen, a nonsteroidal anti-inflammatory drug (NSAID), may result in additive central nervous system (CNS) depression, leading to increased sedation, dizziness, and impaired psychomotor function. Ibuprofen can inhibit the metabolism of olopatadine via competition for hepatic CYP450 enzymes, potentially elevating olopatadine plasma concentrations and prolonging its systemic effects. Clinically, patients may experience exacerbated drowsiness, reduced alertness, and increased risk of falls or accidents, especially in the elderly or those with compromised hepatic function."
"Ibuprofen, a nonsteroidal anti-inflammatory drug (NSAID), can decrease the metabolism of pioglitazone, a thiazolidinedione antidiabetic agent, by inhibiting cytochrome P450 2C8 (CYP2C8) enzyme activity. This inhibition elevates plasma concentrations of pioglitazone, potentially enhancing its hypoglycemic effects and increasing the risk of adverse reactions such as edema, weight gain, and heart failure exacerbation. Clinically, concomitant use may lead to improved glycemic control but also raises concerns for dose-dependent toxicities, necessitating careful monitoring and possible dose adjustment of pioglitazone."
