Clinician-reviewed, head-to-head comparison of mechanism, dosing, pharmacokinetics, and safety profiles.
Last clinically reviewed: July 2026 · OpiCalc Medical Review Team
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.
Acetaminophen is a centrally acting analgesic and antipyretic whose exact mechanism is not fully understood, but is thought to involve inhibition of cyclooxygenase (COX) in the brain and modulation of cannabinoid receptors. Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) that non-selectively inhibits COX-1 and COX-2, reducing prostaglandin synthesis.

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.
Acetaminophen: Severe hepatic impairment, allergy to acetaminophen. Ibuprofen: Hypersensitivity to ibuprofen or other NSAIDs, history of asthma/urticaria after NSAIDs, perioperative pain in CABG surgery, severe heart failure, active GI bleeding, late pregnancy.
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.
Avoid alcohol; take with food or milk to minimize GI irritation. No specific food restrictions.
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.
First trimester: Acetaminophen is considered low risk; ibuprofen is associated with increased risk of miscarriage and cardiac defects. Second trimester: Acetaminophen is safe; ibuprofen is relatively safe but may cause oligohydramnios. Third trimester: Acetaminophen is safe; ibuprofen is contraindicated due to risk of premature closure of ductus arteriosus, oligohydramnios, and neonatal renal impairment.
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.
Acetaminophen: low levels in breast milk, M/P ratio ~0.9; considered compatible with breastfeeding. Ibuprofen: minimal excretion, M/P ratio ~0.01; considered compatible. Combination: low risk with recommended doses.
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.
No standard adjustment for acetaminophen; ibuprofen dosing unchanged in pregnancy but avoid in third trimester; consider increased clearance of acetaminophen in pregnancy but no dose adjustment recommended.
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.
Combination product for acute pain; fixed-dose may exceed recommended daily acetaminophen limit if other acetaminophen-containing products are used. Onset of ibuprofen is 30-60 min, acetaminophen 15-30 min; duration 4-6 hours. Caution in renal impairment (ibuprofen) and hepatic impairment (acetaminophen). Avoid in third trimester of pregnancy.
Do not take more than directed; do not exceed 6 caplets in 24 hours.,Avoid use with other products containing ibuprofen or other NSAIDs, including aspirin, to prevent overdose and serious side effects.,Discontinue use and seek medical attention if symptoms worsen, persist >3 days for sinus or >5 days for pain, or if new symptoms occur.,Take with food or milk to reduce stomach upset; avoid alcohol to lower risk of GI bleeding.,If you have high blood pressure, heart disease, thyroid disease, diabetes, or difficulty urinating due to prostate enlargement, consult a doctor before use.,Do not use if you are taking a prescription monoamine oxidase inhibitor (MAOI) or for 2 weeks after stopping an MAOI drug.,Pregnant or breastfeeding women should not use this product; ibuprofen is contraindicated in third trimester due to risk of premature closure of ductus arteriosus.,Store at room temperature away from moisture and heat.
Do not exceed 10 tablets (500 mg acetaminophen/200 mg ibuprofen) per day.,Do not take with other products containing acetaminophen or NSAIDs.,Take with food or milk to reduce stomach upset.,Avoid alcohol while taking this medication.,Seek medical help if pain persists >10 days or fever >3 days.,Store at room temperature, away from moisture.
No interactions on record
"Concomitant use of Ibuprofen (a nonsteroidal anti-inflammatory drug, NSAID) and Methylprednisolone (a systemic corticosteroid) synergistically increases the risk of gastrointestinal (GI) ulceration, bleeding, and perforation due to additive inhibition of prostaglandin synthesis and mucosal protection. Additionally, Ibuprofen may potentiate the immunosuppressive effects of Methylprednisolone, elevating infection risk. This interaction can lead to serious clinical outcomes, including acute GI hemorrhage, perforation, and impaired wound healing."
"The combination of olopatadine, an antihistamine with sedative properties, and ibuprofen, a nonsteroidal anti-inflammatory drug (NSAID), may result in additive central nervous system (CNS) depression, leading to increased sedation, dizziness, and impaired psychomotor function. Ibuprofen can inhibit the metabolism of olopatadine via competition for hepatic CYP450 enzymes, potentially elevating olopatadine plasma concentrations and prolonging its systemic effects. Clinically, patients may experience exacerbated drowsiness, reduced alertness, and increased risk of falls or accidents, especially in the elderly or those with compromised hepatic function."
"Ibuprofen, a nonsteroidal anti-inflammatory drug (NSAID), can decrease the metabolism of pioglitazone, a thiazolidinedione antidiabetic agent, by inhibiting cytochrome P450 2C8 (CYP2C8) enzyme activity. This inhibition elevates plasma concentrations of pioglitazone, potentially enhancing its hypoglycemic effects and increasing the risk of adverse reactions such as edema, weight gain, and heart failure exacerbation. Clinically, concomitant use may lead to improved glycemic control but also raises concerns for dose-dependent toxicities, necessitating careful monitoring and possible dose adjustment of pioglitazone."
