ADVIL ALLERGY SINUS
Clinical safety rating: caution
Comprehensive clinical and safety monograph for ADVIL ALLERGY SINUS (ADVIL ALLERGY SINUS).
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.
| Metabolism | Ibuprofen: Primarily hepatic via CYP2C9; Pseudoephedrine: Hepatic via N-demethylation and oxidative metabolism; Chlorpheniramine: Hepatic via CYP2D6 and CYP3A4. |
| Excretion | Renal (90% as conjugates and metabolites; <10% unchanged); biliary/fecal (<5%) |
| Half-life | 2–4 hours (pseudoephedrine: 5–8 hours); clinical context: requires q4-6h dosing for pain/fever, q6-8h for congestion |
| Protein binding | Ibuprofen: >99% (albumin); pseudoephedrine: <20% (albumin) |
| Volume of Distribution | Ibuprofen: 0.1–0.2 L/kg; pseudoephedrine: 2.5–3.5 L/kg (extensive tissue distribution) |
| Bioavailability | Ibuprofen: 80–100% oral; pseudoephedrine: >90% oral |
| Onset of Action | Oral: ibuprofen 30–60 min; pseudoephedrine 15–30 min |
| Duration of Action | Ibuprofen: 4–6 hours (pain relief); pseudoephedrine: 4–6 hours (decongestion); clinical note: immediate-release formulation |
| Molecular Weight | 206.3 |
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.
| Dosage form | TABLET |
| Renal impairment | If GFR <30 mL/min: avoid use of ibuprofen component; pseudoephedrine dose interval may need to be increased (every 8-12 hours) due to reduced clearance. |
| Liver impairment | 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. |
| Pediatric use | 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. |
| Geriatric 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. |
| 1st trimester | Avoid use during first trimester due to risk of cardiovascular malformations and gastroschisis associated with NSAID use; ibuprofen is contraindicated after 30 weeks gestation due to risk of premature closure of ductus arteriosus and oligohydramnios; limited data on pseudoephedrine, but may be associated with gastroschisis. |
| 2nd trimester | Use with caution; ibuprofen may be used if benefit outweighs risk, but avoid prolonged use; pseudoephedrine may cause uterine vasoconstriction; consider alternative treatments. |
| 3rd trimester | Contraindicated: ibuprofen is specifically contraindicated after 30 weeks gestation due to risk of premature closure of ductus arteriosus, oligohydramnios, and necrotizing enterocolitis; pseudoephedrine may decrease placental perfusion. |
Clinical note
Comprehensive clinical and safety monograph for ADVIL ALLERGY SINUS (ADVIL ALLERGY SINUS).
| Placental transfer | Ibuprofen crosses the placenta with cord blood concentrations approximately 30% of maternal plasma; pseudoephedrine crosses the placenta readily. |
■ FDA Black Box Warning
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.
| Serious Effects |
Hypersensitivity to ibuprofen, pseudoephedrine, or any componentHistory of asthma, urticaria, or allergic-type reactions after taking aspirin or other NSAIDsSevere hypertensionCoronary artery diseaseConcurrent use of MAOIs or within 14 days of MAOI therapyNarrow-angle glaucomaUrinary retentionThird trimester of pregnancy (after 30 weeks gestation)Active peptic ulcer disease or GI bleedingSevere renal impairment (eGFR <30 mL/min)
| Precautions | 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. |
| Food/Dietary |
Loading safety data…
| Breastfeeding |
| Ibuprofen and pseudoephedrine are excreted into breast milk in small amounts. Ibuprofen is considered compatible with breastfeeding due to low levels; pseudoephedrine may cause irritability or decreased milk production. Monitor infant for CNS stimulation. |
| Lactation Rating | L2 - Safer (ibuprofen), L3 - Moderately Safe (pseudoephedrine); overall rating based on combined components. |
| Teratogenic 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. |
| Fetal Monitoring | Monitor fetal heart rate and amniotic fluid volume if used for prolonged periods. Assess maternal renal function and bleeding time. In third trimester, monitor for ductus arteriosus constriction via fetal echocardiography if exposure occurs. |
| Fertility Effects | Ibuprofen may impair female fertility by inhibiting prostaglandin synthesis affecting ovulation and implantation. Effects are reversible upon discontinuation. Pseudoephedrine may have minimal impact, but no specific data on male fertility. |
| 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. |
| Clinical Pearls | 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. |
| Patient Advice | Do not take if allergic to aspirin or NSAIDs. · Avoid alcohol to reduce risk of stomach bleeding. · Do not use with other products containing NSAIDs or decongestants. · May cause drowsiness; avoid driving or operating machinery. · Do not take for more than 10 days for pain or 3 days for fever. · Consult a doctor if you have high blood pressure, heart disease, glaucoma, or an enlarged prostate. · Pseudoephedrine may cause difficulty sleeping; take last dose at least 4-6 hours before bedtime. · Take with food or milk to minimize stomach upset. |
