Last clinically reviewed: July 2026 · OpiCalc Medical Review Team
H1-receptor antagonist; competes with histamine for H1-receptor sites on effector cells in the gastrointestinal tract, blood vessels, and respiratory tract, blocking histamine-induced bronchoconstriction, vasodilation, and increased capillary permeability.
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.

2.5 mg orally every 4 to 6 hours as needed; maximum 10 mg 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.
Terminal elimination half-life is approximately 20-25 hours in healthy adults; may be prolonged in elderly or patients with hepatic impairment.
2–4 hours (pseudoephedrine: 5–8 hours); clinical context: requires q4-6h dosing for pain/fever, q6-8h for congestion
Hepatic via CYP450 isoenzymes (primarily CYP3A4 and CYP2D6); undergoes N-demethylation and N-oxidation.
Ibuprofen: Primarily hepatic via CYP2C9; Pseudoephedrine: Hepatic via N-demethylation and oxidative metabolism; Chlorpheniramine: Hepatic via CYP2D6 and CYP3A4.
Renal excretion of unchanged drug and metabolites accounts for approximately 60-80% of the administered dose; biliary/fecal elimination comprises the remainder (20-40%).
Renal (90% as conjugates and metabolites; <10% unchanged); biliary/fecal (<5%)
Approximately 90% bound to plasma proteins, primarily albumin.
Ibuprofen: >99% (albumin); pseudoephedrine: <20% (albumin)
2.5-4.0 L/kg, indicating extensive tissue distribution.
Ibuprofen: 0.1–0.2 L/kg; pseudoephedrine: 2.5–3.5 L/kg (extensive tissue distribution)
Oral bioavailability is approximately 50-60% due to first-pass metabolism.
Ibuprofen: 80–100% oral; pseudoephedrine: >90% oral
GFR 10-50 m L/min: 2.5 mg every 6-8 hours; GFR <10 m L/min: 2.5 mg every 8-12 hours.
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 Class A: no adjustment; Child-Pugh Class B: reduce dose by 50%; Child-Pugh Class C: contraindicated.
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.
Children 2-5 years: 1.25 mg orally every 4-6 hours (max 5 mg/day); Children 6-12 years: 1.25-2.5 mg every 4-6 hours (max 7.5 mg/day).
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 1.25 mg orally every 6-8 hours; maximum 5 mg per day due to increased risk of anticholinergic effects and renal 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.
None
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.
May cause drowsiness and impair mental alertness,Avoid alcohol and other CNS depressants,Use with caution in patients with narrow-angle glaucoma, prostatic hypertrophy, or urinary retention,Elderly patients are more susceptible to anticholinergic effects
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 any component,Concurrent use with monoamine oxidase inhibitors
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).
No specific food interactions, but taking with food may reduce GI side effects. Alcohol should be strictly avoided due to additive CNS depression. Grapefruit juice is not documented to interact.
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: Limited human data; animal studies show no teratogenicity. Second and third trimesters: Not associated with major congenital malformations. However, anticholinergic effects may cause neonatal tachycardia, irritability, and withdrawal symptoms if used near term.
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.
Excretion into breast milk likely but negligible amounts; no adverse effects reported in infants. M/P ratio not established. Considered compatible with breastfeeding; monitor for sedation or irritability in neonate.
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.
No specific dose adjustments required in pregnancy; however, use lowest effective dose due to potential anticholinergic effects. Pharmacokinetics may be altered (increased volume of distribution), but no dose adjustment recommended.
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.
ACTIDIL (triprolidine) is a first-generation antihistamine with sedative properties. Use cautiously in elderly due to risk of confusion, urinary retention, and falls. Avoid in patients with narrow-angle glaucoma, BPH, or asthma. Administer with food if GI upset occurs. Onset of action is 30-60 minutes; duration 4-6 hours.
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.
