Clinician-reviewed, head-to-head comparison of mechanism, dosing, pharmacokinetics, and safety profiles.
Last clinically reviewed: July 2026 · OpiCalc Medical Review Team
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.
Ketorolac tromethamine, a nonsteroidal anti-inflammatory drug (NSAID), inhibits prostaglandin synthesis by blocking cyclooxygenase (COX-1 and COX-2) enzymes. This reduces ocular inflammation and pain.
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
Reduction of ocular pain and inflammation following cataract surgery,Treatment of ocular itching associated with seasonal allergic conjunctivitis
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.
1 drop in the affected eye 4 times daily.
2–4 hours (pseudoephedrine: 5–8 hours); clinical context: requires q4-6h dosing for pain/fever, q6-8h for congestion
Terminal elimination half-life is approximately 46 minutes in the aqueous humor following ocular administration in humans.
Ibuprofen: Primarily hepatic via CYP2C9; Pseudoephedrine: Hepatic via N-demethylation and oxidative metabolism; Chlorpheniramine: Hepatic via CYP2D6 and CYP3A4.
Primarily hepatic via conjugation with glucuronic acid; minor role of cytochrome P450 enzymes. Approximately 50% is excreted as parent drug and metabolites in urine.
Renal (90% as conjugates and metabolites; <10% unchanged); biliary/fecal (<5%)
Primarily renal excretion of metabolites; less than 1% excreted unchanged. Biliary/fecal elimination accounts for <10%.
Ibuprofen: >99% (albumin); pseudoephedrine: <20% (albumin)
>99% bound to plasma proteins, primarily albumin.
Ibuprofen: 0.1–0.2 L/kg; pseudoephedrine: 2.5–3.5 L/kg (extensive tissue distribution)
Intravenous administration in animals suggests Vd ~0.15 L/kg, indicating limited distribution; clinically, it distributes into aqueous humor after topical dosing.
Ibuprofen: 80–100% oral; pseudoephedrine: >90% oral
Ocular bioavailability is dependent on formulation; systemic bioavailability after topical ocular administration is extremely low (<1%).
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.
No adjustment required. Drug is minimally systemically absorbed.
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.
No adjustment required. Drug is minimally systemically absorbed.
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.
Safety and efficacy in pediatric patients have not been established.
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.
No specific dosage adjustment is recommended; use same dose as younger adults.
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.
No black box warning for ophthalmic use; however, systemic NSAIDs carry risk of serious cardiovascular and gastrointestinal events. Ophthalmic use rarely associated with corneal adverse events.
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.
Use with caution in patients with bleeding disorders or those on anticoagulants; may prolong bleeding time. Avoid in patients with known hypersensitivities to NSAIDs or aspirin. Can cause corneal keratopathy; discontinue if corneal epithelial breakdown occurs.
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).
Hypersensitivity to any component of the formulation. Active corneal epithelial defect. Patients with aspirin-sensitive asthma.
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.
No specific food interactions; systemic absorption is minimal with ophthalmic use. Avoid concurrent use of other NSAID eye drops due to additive irritation.
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.
Acuvail (ketorolac tromethamine ophthalmic solution) is classified as FDA Pregnancy Category C. Systemic exposure after ocular administration is minimal; however, NSAIDs may cause premature closure of the ductus arteriosus and oligohydramnios in the third trimester. Use during the first and second trimesters should be limited to cases where potential benefit outweighs risk; avoid during the third trimester due to risk of fetal harm.
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.
Ketorolac is excreted in human milk following systemic administration, but ocular doses produce negligible systemic levels. The M/P ratio is not determined for ophthalmic use. Use with caution in nursing mothers, as the clinical significance is likely low due to minimal systemic absorption.
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.
No dosage adjustment is required for ophthalmic use during pregnancy, as systemic exposure is negligible. However, avoid use in third trimester due to risks. Pharmacokinetic changes in pregnancy do not significantly alter ocular delivery.
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.
Acuvail (ketorolac tromethamine ophthalmic solution 0.45%) is a nonsteroidal anti-inflammatory drug (NSAID) for ocular use. It is preserved with sodium chloride and not benzalkonium chloride, reducing corneal epithelial toxicity. Administer 1 drop twice daily for ocular pain and inflammation following cataract surgery. Use caution in patients with bleeding tendencies or those on anticoagulants due to risk of increased ocular bleeding. Monitor for corneal epithelial defects and keratitis, especially with prolonged use.
