CHILDREN'S ADVIL COLD
Clinical safety rating: caution
Comprehensive clinical and safety monograph for CHILDREN'S ADVIL COLD (CHILDREN'S ADVIL COLD).
Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX-1 and COX-2) enzymes, reducing prostaglandin synthesis. Pseudoephedrine is a sympathomimetic amine that acts as a direct and indirect agonist at alpha-adrenergic receptors, causing vasoconstriction and decongestion.
| Metabolism | Ibuprofen: Hepatic metabolism via CYP2C9 and CYP2C19. Pseudoephedrine: Hepatic metabolism via N-demethylation (minor) and renal excretion as unchanged drug. |
| Excretion | Ibuprofen is primarily excreted renally as metabolites (90%) and unchanged drug (10%). Less than 1% is excreted in feces via biliary elimination. Pseudoephedrine is predominantly excreted unchanged in urine (70-90%) with the remainder as inactive metabolites; renal elimination is pH-dependent with enhanced excretion in acidic urine. |
| Half-life | Ibuprofen: terminal elimination half-life is 1.8-2.5 hours in children; no significant accumulation with recommended dosing. Pseudoephedrine: half-life is 4-6 hours in children (9-16 hours in adults); prolonged in renal impairment or alkaline urine. |
| Protein binding | Ibuprofen: 99% bound primarily to albumin. Pseudoephedrine: minimal binding (20-30%) to plasma proteins. |
| Volume of Distribution | Ibuprofen: Vd is 0.1-0.2 L/kg in children, approximating plasma volume; low Vd reflects high protein binding. Pseudoephedrine: Vd is 2.6-3.3 L/kg in children, indicating extensive tissue distribution. |
| Bioavailability | Ibuprofen: oral bioavailability is 80-100% (suspension). Pseudoephedrine: oral bioavailability is 100% (well absorbed with no first-pass effect). |
| Onset of Action | Ibuprofen: oral onset of antipyretic/analgesic effect is 30-60 minutes. Pseudoephedrine: oral onset of decongestant effect is 30 minutes. |
| Duration of Action | Ibuprofen: duration of antipyretic/analgesic effect is 6-8 hours. Pseudoephedrine: duration of decongestant effect is 4-6 hours; may be prolonged in children. |
Ibuprofen 200 mg and pseudoephedrine 30 mg orally every 4-6 hours as needed, not exceeding 6 doses per day.
| Dosage form | SUSPENSION |
| Renal impairment | GFR 30-59 mL/min: reduce dose by 50% or extend interval; GFR <30 mL/min: contraindicated. |
| Liver impairment | Child-Pugh Class A: no adjustment; Class B: reduce dose by 50%; Class C: contraindicated. |
| Pediatric use | Children 6-12 years: 5 mL (100 mg ibuprofen/15 mg pseudoephedrine) every 6-8 hours; max 4 doses/day. Weight-based: ibuprofen 5-10 mg/kg/dose, pseudoephedrine 1 mg/kg/dose every 6-8 hours. |
| Geriatric use | Start at low end of dosing; monitor renal function; avoid if GFR <30 mL/min; increased risk of NSAID adverse effects. |

Clinical note
Comprehensive clinical and safety monograph for CHILDREN'S ADVIL COLD (CHILDREN'S ADVIL COLD).
| Breastfeeding | Ibuprofen is excreted in breast milk in very low levels (M/P ratio ~0.32); pseudoephedrine levels are about 1-2% of maternal dose per day. Use caution as pseudoephedrine may reduce milk production. Generally considered compatible with breastfeeding short-term. |
| Teratogenic Risk | First trimester: NSAIDs (ibuprofen component) are associated with increased risk of cardiac defects and gastroschisis; second trimester: risk is low; third trimester: NSAIDs increase risk of premature ductus arteriosus closure and oligohydramnios. Decongestant (pseudoephedrine) is associated with increased risk of gastroschisis and small intestinal atresia in first trimester. Use contraindicated after 30 weeks gestation. |
■ FDA Black Box Warning
NSAIDs may cause an increased risk of serious cardiovascular thrombotic events, myocardial infarction, and stroke, which can be fatal. Risk may increase with duration of use. Contraindicated for treatment of peri-operative pain in the setting of coronary artery bypass graft (CABG) surgery.
| Serious Effects |
Hypersensitivity to ibuprofen, pseudoephedrine, or other NSAIDs; history of asthma, urticaria, or allergic-type reactions after taking aspirin or other NSAIDs; peri-operative pain in CABG surgery; severe hypertension; coronary artery disease; concurrent MAO inhibitor use; urinary retention; and in children <2 years of age (unless directed by a doctor).
| Precautions | Cardiovascular risk, gastrointestinal bleeding/ulceration, renal toxicity, hypertension, hypersensitivity reactions, asthma exacerbation, and use in pediatric patients requiring careful dosing and monitoring. |
| Food/Dietary | Avoid high-tyramine foods (aged cheese, cured meats) due to pseudoephedrine's MAOI-like effect at high doses. Caffeine may increase stimulant effect. Take with food to reduce GI irritation. |
Loading safety data…
| Fetal Monitoring | Monitor for oligohydramnios and fetal ductus arteriosus constriction if used beyond 30 weeks. Monitor maternal blood pressure, renal function, and signs of bleeding. Ultrasound monitoring for fetal anomalies if first-trimester exposure. |
| Fertility Effects | Ibuprofen may impair female fertility via reversible inhibition of ovulation through prostaglandin-mediated effects. Pseudoephedrine may affect sperm motility at high doses. Effects are reversible upon discontinuation. |
| Clinical Pearls | Children's Advil Cold contains ibuprofen (NSAID) and pseudoephedrine (decongestant). Avoid in children <6 years due to risk of adverse effects. Contraindicated in dehydration, hypertension, or viral illness (Reye's syndrome risk). Use lowest effective dose for shortest duration. Do not combine with other NSAIDs or sympathomimetics. |
| Patient Advice | Do not exceed 4 doses in 24 hours. · Give with food to reduce stomach upset. · Stop use and consult doctor if symptoms worsen or persist >7 days. · Avoid in children with heart disease, high blood pressure, or thyroid disease unless directed by doctor. · Do not use with other products containing NSAIDs or decongestants. |
