Clinician-reviewed, head-to-head comparison of mechanism, dosing, pharmacokinetics, and safety profiles.
Last clinically reviewed: July 2026 · OpiCalc Medical Review Team
Acetaminophen: analgesic and antipyretic effects via inhibition of cyclooxygenase (COX) and activation of descending serotonergic pathways; central action. Hydrocodone: mu-opioid receptor agonist; activates G-protein coupled receptors to modulate pain perception and emotional response.
Pseudoephedrine is a sympathomimetic amine that directly stimulates alpha-adrenergic receptors, causing vasoconstriction of nasal mucosa and sinus vessels. Chlorpheniramine is an alkylamine antihistamine that competitively antagonizes histamine H1 receptors, reducing allergic symptoms. Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX-1 and COX-2) enzymes, decreasing prostaglandin synthesis and reducing pain, fever, and inflammation.
Moderate to moderately severe pain,Cough suppression (hydrocodone; off-label)
Temporary relief of nasal congestion, sinus pressure, sneezing, runny nose, itchy/watery eyes, and headache due to colds or allergies,Fever reduction,Minor aches and pains
1-2 tablets (containing 5-10 mg hydrocodone and 300-325 mg acetaminophen) orally every 4-6 hours as needed for pain; maximum 8 tablets per day.
1-2 tablets (each tablet contains ibuprofen 200 mg and pseudoephedrine HCl 30 mg) orally every 4-6 hours as needed; maximum 6 tablets per day.
Acetaminophen: 2-3 hours in adults; prolonged in hepatic impairment (up to 5 hours). Hydrocodone: 3.8-4.5 hours (range 3-5 hours) in healthy adults; prolonged in elderly or hepatic/renal impairment. Clinical context: repeated dosing may require extended intervals in renal impairment.
2–4 hours (pseudoephedrine: 5–8 hours); clinical context: requires q4-6h dosing for pain/fever, q6-8h for congestion
Acetaminophen: primarily via glucuronidation (UGT1A1, UGT1A6, UGT1A9) and sulfation; minor CYP2E1 oxidation to NAPQI (toxic metabolite). Hydrocodone: CYP3A4 and CYP2D6; N-demethylation to norhydrocodone; O-demethylation to hydromorphone (CYP2D6).
Ibuprofen: Primarily hepatic via CYP2C9; Pseudoephedrine: Hepatic via N-demethylation and oxidative metabolism; Chlorpheniramine: Hepatic via CYP2D6 and CYP3A4.
Acetaminophen: primarily renal excretion of conjugated metabolites (glucuronide and sulfate) with approximately 5% excreted unchanged. Hydrocodone: renal excretion as unchanged drug and metabolites (O-demethylated and N-demethylated); total renal excretion accounts for about 60-70% of dose (parent and metabolites). Biliary/fecal elimination is minimal.
Renal (90% as conjugates and metabolites; <10% unchanged); biliary/fecal (<5%)
Acetaminophen: 10-25% bound, nonspecific binding to albumin. Hydrocodone: 25-50% bound, primarily to albumin and alpha-1-acid glycoprotein.
Ibuprofen: >99% (albumin); pseudoephedrine: <20% (albumin)
Acetaminophen: 0.8-1.0 L/kg, indicating distribution into total body water; clinically relevant for loading dose calculations. Hydrocodone: 3.0-4.0 L/kg, suggesting extensive tissue distribution; higher Vd may require higher loading doses but has no clinical target.
Ibuprofen: 0.1–0.2 L/kg; pseudoephedrine: 2.5–3.5 L/kg (extensive tissue distribution)
Acetaminophen: oral bioavailability 85-95% (first-pass metabolism minimal). Hydrocodone: oral bioavailability about 25-45% due to first-pass hepatic metabolism; significant interindividual variability.
Ibuprofen: 80–100% oral; pseudoephedrine: >90% oral
GFR 10-50 m L/min: administer every 6 hours; GFR <10 m L/min: administer every 8 hours; avoid in severe impairment due to acetaminophen metabolite accumulation.
If GFR <30 m L/min: avoid use of ibuprofen component; pseudoephedrine dose interval may need to be increased (every 8-12 hours) due to reduced clearance.
Child-Pugh A: no adjustment; Child-Pugh B: reduce dose by 50% or extend interval; Child-Pugh C: use with caution, avoid if possible, consider alternative therapy.
Child-Pugh Class A: no adjustment; Class B: use with caution, maximum ibuprofen dose 1200 mg/day; Class C: contraindicated due to risk of hepatotoxicity and renal impairment.
Dosing based on hydrocodone component: 0.1-0.2 mg/kg/dose every 4-6 hours; maximum daily acetaminophen limit: 75 mg/kg/day; not recommended for children <2 years.
Not recommended for children under 12 years of age; for children ≥12 years: same as adult dose (200 mg ibuprofen/30 mg pseudoephedrine) every 4-6 hours, maximum 6 tablets per day.
Initiate at lowest effective dose, typically 1 tablet (2.5-5 mg hydrocodone) every 6 hours; monitor for respiratory depression and acetaminophen toxicity; avoid in frail elderly with hepatic impairment.
Initiate at lowest effective dose (1 tablet every 6-8 hours); monitor renal function and blood pressure due to increased risk of GI bleeding, cardiovascular events, and pseudoephedrine-induced hypertension.
Addiction, abuse, and misuse; life-threatening respiratory depression; accidental ingestion of acetaminophen; neonatal opioid withdrawal syndrome; interaction with alcohol; risk of medication errors.
No FDA black box warning exists for this combination product. However, NSAIDs like ibuprofen carry a black box warning for increased risk of serious cardiovascular thrombotic events, myocardial infarction, and stroke, which can be fatal, especially with prolonged use or in patients with cardiovascular risk factors.
Hepatotoxicity from acetaminophen overdose; respiratory depression; increased intracranial pressure; CNS depression; elderly/debilitated patients; renal impairment; opioid-induced hyperalgesia; serotonin syndrome; interaction with CNS depressants; risk of adrenal insufficiency; severe hypotension; use in patients with gastrointestinal obstruction; convulsion risk; severe hepatic impairment; urinary retention; acute abdominal conditions; hypothyroidism; prostatic hypertrophy; adrenocortical insufficiency; pregnancy/lactation; pediatric use; geriatric use; renal impairment; hepatic impairment.
Cardiovascular risk: NSAIDs increase risk of serious cardiovascular events. Gastrointestinal risk: NSAIDs can cause bleeding, ulceration, and perforation. Hypertension: Pseudoephedrine may elevate blood pressure. Avoid use with MAOIs or within 14 days of stopping. Caution in hyperthyroidism, diabetes, glaucoma, prostatic hypertrophy, and renal impairment.
Hypersensitivity to acetaminophen or hydrocodone; significant respiratory depression; acute or severe bronchial asthma; upper airway obstruction; known or suspected gastrointestinal obstruction; paralytic ileus; concomitant use of monoamine oxidase inhibitors (MAOIs) or within 14 days; severe hepatic impairment (acetaminophen toxicity risk); acute alcoholism.
Hypersensitivity to any component; Concurrent MAOI therapy; Severe hypertension or coronary artery disease; Active peptic ulcer disease; History of aspirin/NSAID-induced asthma; Pregnancy (especially third trimester); Children under 12 years (per product labeling).
Avoid alcohol consumption during therapy; ethanol increases acetaminophen hepatotoxicity risk and enhances CNS depression. Grapefruit juice may inhibit CYP2D6 (minor effect) but no significant clinical interaction. No other specific food restrictions.
Avoid alcohol due to increased risk of GI bleeding and liver toxicity. No known food interactions with chlorpheniramine or pseudoephedrine. Taking with food may reduce gastric irritation from ibuprofen.
First trimester: Acetaminophen considered low risk; hydrocodone is a pregnancy category C drug. Data from retrospective studies suggest a small increased risk of certain congenital malformations (e.g., neural tube defects, cleft palate) with first trimester opioid use, but absolute risk is low. Second trimester: Low risk as above. Third trimester: Prolonged use of hydrocodone can cause neonatal opioid withdrawal syndrome (NOWS); acetaminophen is safe. Use only if benefit outweighs risk.
First trimester: NSAIDs are associated with increased risk of miscarriage and congenital malformations (cardiac defects, gastroschisis). Third trimester: Risk of premature closure of ductus arteriosus, oligohydramnios, and necrotizing enterocolitis. Avoid use after 30 weeks gestation.
Acetaminophen excretion in breast milk is low (M/P ratio ~0.9). Hydrocodone is excreted in small amounts (M/P ratio ~2.1). The relative infant dose is estimated to be 2.5-3.5% of maternal weight-adjusted dose for hydrocodone. Monitor infant for sedation and respiratory depression. Consider benefit to mother and potential neonatal opioid withdrawal if used chronically.
Ibuprofen and pseudoephedrine are excreted into breast milk. Ibuprofen has low milk/plasma ratio (0.01-0.07) and is generally considered compatible. Pseudoephedrine may reduce milk production and cause irritability in infants. Use with caution, especially in preterm infants.
During pregnancy, increased plasma volume and enhanced hepatic clearance may reduce serum concentrations of both drugs. However, dosing adjustments are not routinely recommended due to risk of undertreatment. Use the lowest effective dose of hydrocodone for the shortest duration. For acetaminophen, maximum daily dose should not exceed 3000 mg to avoid hepatotoxicity.
No specific dose adjustments recommended for pregnancy; however, use the lowest effective dose for the shortest duration. Avoid in third trimester. Pseudoephedrine dose remains standard; caution in hypertensive disorders.
Acetaminophen-hydrocodone is contraindicated in severe respiratory depression, acute or severe bronchial asthma, and known hypersensitivity. Monitor for respiratory depression, especially in elderly or debilitated patients. Avoid use with other acetaminophen-containing products to prevent hepatotoxicity. Hydrocodone is a prodrug metabolized by CYP2D6 to hydromorphone; CYP2D6 ultrarapid metabolizers may experience toxicity. Use with caution in patients with head injury, increased intracranial pressure, or severe hepatic impairment. Naloxone is the reversal agent for opioid effects; acetylcysteine for acetaminophen overdose.
Advil Allergy Sinus contains ibuprofen (NSAID), chlorpheniramine (first-generation antihistamine), and pseudoephedrine (decongestant). Avoid in patients with aspirin/NSAID allergy, severe hypertension, coronary artery disease, or MAOI use. Caution in elderly due to anticholinergic effects. Pseudoephedrine may cause insomnia and anxiety; avoid evening dosing.
Take exactly as prescribed; do not increase dose or frequency without consulting your doctor.,Avoid alcohol and other CNS depressants (e.g., benzodiazepines, sedatives) as they increase risk of severe drowsiness and respiratory depression.,Do not exceed 4000 mg of acetaminophen per day from all sources; check labels of other medications.,This medication may cause dizziness or drowsiness; avoid driving or operating heavy machinery until you know how it affects you.,Store securely out of reach of others, especially children, as misuse can cause overdose and death.,Do not stop abruptly; withdrawal may occur.

"Hydrocodone, an opioid agonist, and scopolamine, an anticholinergic agent, both exhibit central nervous system (CNS) depressant effects. When co-administered, their combined activity can lead to additive CNS depression, resulting in enhanced sedation, respiratory depression, and cognitive impairment. This interaction may also increase the risk of constipation and urinary retention due to additive anticholinergic effects from both drugs."
"Pargyline, a monoamine oxidase inhibitor (MAOI), irreversibly inhibits the metabolism of amines, leading to increased intraneuronal stores of norepinephrine. Hydrocodone, a semisynthetic opioid, can release these stored catecholamines, potentially causing a hypertensive crisis, serotonin syndrome, or CNS excitation. Coadministration may also result in excessive sedation and respiratory depression due to additive CNS depressant effects, requiring immediate clinical attention."
"Hydrocodone, an opioid agonist, and oxprenolol, a non-selective beta-adrenoceptor antagonist, are both central nervous system (CNS) depressants. Their combined use can lead to additive CNS depression, resulting in excessive sedation, respiratory depression, hypotension, and bradycardia. This interaction is particularly dangerous in patients with compromised cardiac or respiratory function, potentially leading to coma or death."
