Pseudoephedrine is a sympathomimetic amine that acts as a decongestant by stimulating alpha-adrenergic receptors in the respiratory tract mucosa, causing vasoconstriction and reducing nasal congestion.
Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX-1 and COX-2), reducing prostaglandin synthesis, leading to analgesic, anti-inflammatory, and antipyretic effects. Pseudoephedrine is a sympathomimetic amine that directly acts on alpha-adrenergic receptors in the nasal mucosa, causing vasoconstriction and reducing nasal congestion.

500 mg orally twice daily with meals.
1-2 tablets (each containing ibuprofen 200 mg and pseudoephedrine 30 mg) orally every 4-6 hours as needed; maximum 6 tablets in 24 hours. Do not exceed 1200 mg ibuprofen and 180 mg pseudoephedrine per day.
3-5 hours in adults with normal renal function; prolonged to 12-24 hours in severe renal impairment (Cr Cl <30 m L/min).
Ibuprofen: 2-4 hours (terminal; rapid elimination, no accumulation with intermittent use). Pseudoephedrine: 4-8 hours (terminal; prolonged in alkaline urine, up to 16 hours at p H 8).
Hepatic metabolism via N-demethylation to active metabolite; undergoes some phase I and phase II metabolism; excreted renally.
Ibuprofen is primarily metabolized by CYP2C9 and CYP2C8. Pseudoephedrine is partially metabolized in the liver by N-demethylation.
Primarily renal (85-90% as unchanged drug) via glomerular filtration and tubular secretion; minor biliary/fecal excretion (5-10%).
Renal excretion of unchanged drug and metabolites: ibuprofen ~45-60% (primarily as conjugated metabolites, <10% unchanged), pseudoephedrine ~70-90% unchanged. Biliary/fecal elimination accounts for <10% for both components.
25-30% bound to serum albumin.
Ibuprofen: ~99% primarily to albumin. Pseudoephedrine: negligible (<10% bound to plasma proteins).
1-2 L/kg, indicating extensive tissue distribution.
Ibuprofen: 0.1-0.2 L/kg (low Vd, indicating limited tissue distribution). Pseudoephedrine: 2.5-3.5 L/kg (high Vd, extensive tissue distribution including CNS).
Oral: 60-70% due to first-pass metabolism.
Oral: ibuprofen ~80-100% (rapidly absorbed, no significant first-pass). Pseudoephedrine ~100% (well absorbed, minimal first-pass metabolism).
GFR ≥60 m L/min: 500 mg twice daily. GFR 30-59: 500 mg once daily. GFR <30: 500 mg every other day.
GFR 30-89 m L/min: Use lowest effective dose for shortest duration; monitor renal function. GFR <30 m L/min or dialysis: Contraindicated.
Child-Pugh A: no adjustment. Child-Pugh B: reduce dose by 25%. Child-Pugh C: reduce dose by 50%.
Child-Pugh Class A: No adjustment; use with caution. Child-Pugh Class B or C: Avoid use.
Not recommended for pediatric use; safety and efficacy not established.
Children <12 years: Do not use. Children ≥12 years: Same as adult dosing; 1-2 tablets every 4-6 hours as needed; maximum 6 tablets in 24 hours.
No specific dose adjustment required, but monitor renal function and adjust accordingly per renal adjustment guidelines.
Use lowest effective dose for shortest duration; avoid chronic use. Reduce initial dose to 1 tablet every 6-8 hours due to increased risk of renal impairment, GI bleeding, and cardiovascular events.
None
Nonsteroidal anti-inflammatory drugs (NSAIDs) cause an increased risk of serious cardiovascular thrombotic events, including myocardial infarction and stroke, which can be fatal. This risk may increase with duration of use. Patients with cardiovascular disease or risk factors for cardiovascular disease may be at greater risk. NSAIDs are contraindicated for the treatment of perioperative pain in the setting of coronary artery bypass graft (CABG) surgery.
Use with caution in hypertension, coronary artery disease, hyperthyroidism, diabetes, prostatic hypertrophy, and glaucoma. Avoid in patients with severe or uncontrolled hypertension. Prolonged use may lead to rebound congestion.
Cardiovascular thrombotic events, gastrointestinal bleeding/ulceration/perforation, hypertension, renal toxicity, serious skin reactions, anaphylactoid reactions, exacerbation of asthma, and drug interactions including with ACE inhibitors, diuretics, and lithium.
Severe hypertension, severe coronary artery disease, concurrent use of MAO inhibitors, narrow-angle glaucoma, urinary retention, and hypersensitivity to pseudoephedrine.
Hypersensitivity to ibuprofen, aspirin, or other NSAIDs; history of asthma, urticaria, or allergic-type reactions after taking aspirin or other NSAIDs; patients with severe hypertension or coronary artery disease; patients taking monoamine oxidase inhibitors (MAOIs) or within 14 days of stopping MAOIs; concurrent use of other sympathomimetics; in the setting of CABG surgery.
Avoid high-tyramine foods (aged cheese, cured meats, fermented products) as pseudoephedrine may cause hypertensive crisis with MAOIs; do not use MYFED if you have taken an MAOI in the last 14 days. Grapefruit and grapefruit juice may increase anticholinergic effects.
Take with food or milk to reduce gastrointestinal irritation. Avoid alcohol consumption as it increases the risk of NSAID-related gastric ulcers and bleeding. High-sodium foods may exacerbate hypertension in patients sensitive to the pressor effects of pseudoephedrine.
Category C: First trimester risk of major malformations not clearly increased; second and third trimester use associated with fetal tachycardia, premature closure of ductus arteriosus, and oligohydramnios. Avoid in third trimester.
First trimester: Ibuprofen (NSAID) is associated with increased risk of miscarriage and congenital malformations, particularly cardiac defects, with odds ratio 1.86 (95% CI 1.32-2.62) for any malformation and 1.86 (95% CI 1.32-2.62) for cardiac malformations. Second trimester: Risk of oligohydramnios and premature closure of ductus arteriosus after 20 weeks. Third trimester: Avoid after 30 weeks due to risk of premature ductus arteriosus closure and oligohydramnios; after 32 weeks, increased risk of necrotizing enterocolitis, intracranial hemorrhage, and renal impairment in neonate (renal agenesis/dysgenesis). Pseudoephedrine: First trimester – possible increased risk of gastroschisis (odds ratio 1.8, 95% CI 1.0-3.2) and small intestinal atresia. Second and third trimesters: potential uteroplacental vasoconstriction leading to fetal hypoxia; risk of prematurity and low birth weight.
Excreted in breast milk; M/P ratio not established. Potential for infant irritability and sleep disturbance. Use caution; manufacturers recommend avoiding during breastfeeding.
Ibuprofen: M/P ratio 0.005–0.006; low transfer into breast milk; AAP compatible; theoretical risk of platelet dysfunction in neonate. Pseudoephedrine: M/P ratio 2.6–3.5 (concentrated in milk); estimated infant dose 4.3% of maternal weight-adjusted dose; may cause irritability and sleep disturbances in infant; may reduce milk production by up to 24%. Caution advised; avoid in lactation if possible.
No standard dose adjustment recommended for pregnancy. Increased renal clearance and volume of distribution may reduce peak concentrations; however, no evidence-based dose change is indicated. Use lowest effective dose for shortest duration.
Ibuprofen: No dose adjustment required; however, use lowest effective dose and shortest duration; avoid after 30 weeks gestation. Pseudoephedrine: No specific dose adjustment recommended based on pharmacokinetic changes, but use with caution due to vasoconstrictive effects; reduced efficacy may be observed due to increased plasma volume and renal clearance.
MYFED is a combination of pseudoephedrine (decongestant) and triprolidine (antihistamine). Avoid in patients with severe hypertension, coronary artery disease, or narrow-angle glaucoma. Use caution in elderly due to anticholinergic effects (confusion, urinary retention). May cause CNS stimulation or sedation; assess patient's response before driving.
Advil Cold and Sinus is a fixed-dose combination of ibuprofen (NSAID) and pseudoephedrine (decongestant). Ibuprofen inhibits COX-1/2, reducing prostaglandin synthesis, while pseudoephedrine is an α-adrenergic agonist causing vasoconstriction in nasal mucosa. Use cautiously in patients with hypertension, cardiovascular disease, or renal impairment due to pseudoephedrine's pressor effects and ibuprofen's potential to reduce renal blood flow and antagonize antihypertensives. Avoid in patients with severe coronary artery disease, uncontrolled hypertension, or concurrent MAOI use. Max duration: 3 days for sinus symptoms, 5 days for pain. Monitor for NSAID-induced GI bleeding, especially in elderly or those on anticoagulants/aspirin.
