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.
Angiotensin II receptor blocker (ARB) that selectively inhibits the binding of angiotensin II to AT1 receptors, causing vasodilation and reduced aldosterone secretion.
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
Hypertension,Diabetic nephropathy in patients with type 2 diabetes and hypertension,Heart failure (NYHA class II-IV) as adjunctive therapy,Stroke prevention in hypertensive patients with left ventricular hypertrophy
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.
5 mg orally once daily, increased at 2-week intervals to a maximum of 10 mg once daily if needed.
2–4 hours (pseudoephedrine: 5–8 hours); clinical context: requires q4-6h dosing for pain/fever, q6-8h for congestion
12-16 hours in adults with normal renal function; prolonged to 24-48 hours in severe renal impairment
Ibuprofen: Primarily hepatic via CYP2C9; Pseudoephedrine: Hepatic via N-demethylation and oxidative metabolism; Chlorpheniramine: Hepatic via CYP2D6 and CYP3A4.
Primarily metabolized by CYP2C9 to inactive metabolites; also undergoes glucuronidation.
Renal (90% as conjugates and metabolites; <10% unchanged); biliary/fecal (<5%)
Primarily renal excretion (70-80% unchanged) with minor biliary/fecal elimination (10-15%)
Ibuprofen: >99% (albumin); pseudoephedrine: <20% (albumin)
95-98% bound primarily to albumin
Ibuprofen: 0.1–0.2 L/kg; pseudoephedrine: 2.5–3.5 L/kg (extensive tissue distribution)
0.2-0.4 L/kg indicating moderate tissue distribution
Ibuprofen: 80–100% oral; pseudoephedrine: >90% oral
Oral: 60-75%; complete with IV administration
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 dose adjustment required for GFR ≥30 m L/min. For GFR <30 m L/min, reduce dose by 50% or increase dosing interval to every other day.
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.
Child-Pugh A: No adjustment. Child-Pugh B: Reduce dose by 50%. Child-Pugh C: Use not recommended.
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.
Not approved for pediatric use.
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.
Initiate at 2.5 mg once daily; titrate slowly due to increased sensitivity and risk of falls.
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.
None
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.
Fetal toxicity: Use in pregnancy can cause fetal harm; discontinue as soon as possible when pregnancy is detected,Hypotension in volume-depleted patients,Renal function deterioration in patients with bilateral renal artery stenosis or single kidney,Hyperkalemia, especially in renal impairment or concomitant use of potassium-sparing diuretics,Avoid use with aliskiren in patients with diabetes
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).
Pregnancy (second and third trimesters),Hypersensitivity to bepadin or any component,Concomitant use with aliskiren in patients with diabetes or renal impairment (GFR <60 m L/min)
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 significant food interactions reported. Grapefruit juice does not affect bepotastine metabolism. Avoid excessive alcohol intake due to potential for increased sedation.
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.
Limited data in humans. In animal studies, no teratogenic effects at therapeutic doses. Increased risk of fetal loss and reduced fetal weight at toxic doses. First trimester: avoid unless benefit outweighs risk. Second/third trimester: use with caution; may cause fetal bradycardia and hypotension.
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.
Not known if excreted in human milk. M/P ratio not established. Caution advised; consider risk-benefit. Monitor infant for excessive sedation and feeding difficulties.
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 standard dose adjustment recommended; however, increased renal clearance and volume of distribution may require dose increase or more frequent administration. Monitor clinical response and adjust based on therapeutic drug monitoring if available.
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.
BEPADIN (bepotastine besilate), a second-generation antihistamine, is indicated for allergic rhinitis and urticaria. It does not require hepatic metabolism, making it suitable for patients with liver impairment. Onset of action is within 1 hour. Avoid concurrent use with CNS depressants due to additive sedative effects.
