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, which mediates inflammation, pain, and fever. Pseudoephedrine is a sympathomimetic amine that acts as a decongestant by stimulating alpha-adrenergic receptors in the nasal mucosa, causing vasoconstriction.
Dihydropyridine calcium channel blocker; inhibits calcium ion influx across cardiac and vascular smooth muscle cells, reducing peripheral vascular resistance and blood pressure.
Temporary relief of symptoms due to hay fever or other upper respiratory allergies: nasal congestion, sinus pressure, sneezing, runny nose, itching of nose or throat, and itchy, watery eyes due to allergies.,Temporary reduction of fever.,Relief of minor aches and pains associated with the common cold, headache, toothache, muscular aches, backache, menstrual cramps, and arthritis pain.
Hypertension,Chronic stable angina,Vasospastic angina (Prinzmetal's angina)
Ibuprofen 200 mg and pseudoephedrine HCl 30 mg per tablet. Usual adult dose: 1-2 tablets orally every 4-6 hours as needed, not to exceed 6 tablets in 24 hours.
10-20 mg orally three times daily; extended-release: 30-60 mg orally once daily; maximum 120 mg/day.
Ibuprofen: 2-4 hours; pseudoephedrine: 5-8 hours. Shorter half-life requires frequent dosing for sustained relief.
Terminal elimination half-life: 2-5 hours (immediate-release); 8-14 hours (extended-release). Context: shorter half-life necessitates multiple daily dosing for immediate-release; extended-release allows once-daily dosing.
Ibuprofen is primarily metabolized by cytochrome P450 (CYP) enzymes, mainly CYP2C9, to inactive metabolites (hydroxyibuprofen and carboxyibuprofen). Pseudoephedrine is partially metabolized in the liver by N-demethylation to an inactive metabolite.
Hepatic via CYP3A4; extensive first-pass metabolism; metabolites are inactive.
Renal excretion of unchanged drug and metabolites; approximately 1% excreted unchanged (pseudoephedrine) and 15% (ibuprofen). Biliary/fecal elimination accounts for <5%.
Renal: 70-80% as metabolites; Fecal: 15-20% as metabolites; <1% unchanged in urine
Ibuprofen: 99% bound to albumin; pseudoephedrine: negligible protein binding.
92-98% bound to plasma proteins (albumin and alpha-1-acid glycoprotein)
Ibuprofen: 0.1-0.2 L/kg; pseudoephedrine: 2.5-3 L/kg.
0.8-1.2 L/kg. Clinical meaning: indicates extensive tissue distribution, consistent with high lipophilicity.
Oral: ibuprofen 80-100%; pseudoephedrine 100%.
Oral immediate-release: 45-60% (due to first-pass metabolism); extended-release: 60-85% (due to slower release and reduced first-pass effect).
For pseudoephedrine: Cr Cl <30 m L/min, reduce dose by 50% or administer every 12 hours. For ibuprofen: avoid use if Cr Cl <30 m L/min; if Cr Cl 30-59 m L/min, use lowest effective dose and monitor renal function.
No dose adjustment required for GFR ≥30 m L/min; for GFR <30 m L/min, use with caution and reduce initial dose by 50%.
For ibuprofen: Child-Pugh class A and B: no adjustment necessary; Child-Pugh class C: avoid use. For pseudoephedrine: use with caution in severe hepatic impairment; no specific dose adjustment recommended, but monitor for adverse effects.
Child-Pugh Class A: no adjustment; Class B: reduce dose by 50%; Class C: avoid use or reduce by 75%.
Not indicated for children under 12 years of age. For children 12 years and older: same as adult dose (1-2 tablets every 4-6 hours, max 6 tablets per day). Weight-based: not routinely used; safety and efficacy not established for <25 kg.
0.25-0.5 mg/kg/dose orally every 6-8 hours; maximum 3 mg/kg/day. Extended-release not recommended.
For ibuprofen: use lowest effective dose for shortest duration; monitor renal function and GI bleeding risk. For pseudoephedrine: initiate at lower doses (e.g., one tablet every 6 hours) due to increased sensitivity and risk of hypertension, urinary retention, and CNS effects.
Start at 10 mg orally twice daily; titrate slowly due to increased sensitivity and risk of hypotension.
Cardiovascular risk: NSAIDs may increase the risk of serious cardiovascular thrombotic events, myocardial infarction, and stroke, which can be fatal. Risk increases with duration of use and in patients with cardiovascular risk factors. Contraindicated for perioperative pain in coronary artery bypass graft (CABG) surgery. Gastrointestinal risk: NSAIDs increase the risk of serious gastrointestinal adverse events including bleeding, ulceration, and perforation of the stomach or intestines, which can be fatal. Elderly patients and those with prior peptic ulcer disease and/or GI bleeding are at greater risk.
None
Cardiovascular effects: may increase risk of heart attack or stroke; use lowest effective dose for shortest duration. Gastrointestinal effects: may cause GI ulceration, bleeding, perforation. Renal effects: avoid in advanced renal disease; monitor renal function. Hepatic effects: may cause liver enzyme elevation; discontinue if liver disease develops. Anaphylactic reactions: may occur in patients with or without prior NSAID sensitivity. Asthma: may cause bronchospasm. Hypertension: may worsen hypertension. Avoid in late pregnancy due to risk of premature closure of ductus arteriosus. Pseudoephedrine: may cause nervousness, dizziness, insomnia, hypertension, arrhythmias; use with caution in patients with cardiovascular disease, diabetes, glaucoma, prostatic hypertrophy, hyperthyroidism. Avoid in severe hypertension or coronary artery disease.
May cause hypotension, especially in patients on beta-blockers or with poor cardiac reserve,Risk of increased angina and/or myocardial infarction upon initiation or dose increase,Peripheral edema,Stevens-Johnson syndrome and toxic epidermal necrolysis (rare),Hepatic impairment,Exacerbation of angina on withdrawal
Hypersensitivity to ibuprofen, pseudoephedrine, or any component of the formulation. History of asthma, urticaria, or allergic-type reaction after taking aspirin or other NSAIDs. In the setting of coronary artery bypass graft (CABG) surgery. Severe hypertension. Coronary artery disease. Concurrent use with or within 14 days of monoamine oxidase inhibitors (MAOIs) due to risk of hypertensive crisis. Pregnancy (third trimester).
Hypersensitivity to nifedipine,Cardiogenic shock,Significant aortic stenosis,Concurrent use with rifampin,Pregnancy (category C)
Take with food or milk to minimize GI upset. Avoid alcohol as it may increase risk of GI bleeding. No specific food-drug interactions.
Avoid grapefruit and grapefruit juice; they inhibit CYP3A4 and increase nifedipine serum concentrations, leading to enhanced hypotensive effects and risk of toxicity. Grapefruit interaction persists for 24 hours; separate consumption by at least 4 hours if unavoidable, but preferable to avoid entirely. Avoid alcohol which can increase hypotension. High-fat meals may reduce absorption of extended-release formulations; take consistently with or without food.
First trimester: Possible increased risk of cardiovascular malformations and gastroschisis with NSAID use. Second trimester: No specific malformation risk reported, but avoid prolonged use due to potential oligohydramnios. Third trimester: NSAIDs (including ibuprofen) are contraindicated due to risk of premature ductus arteriosus closure and oligohydramnios. Pseudoephedrine: Limited data; possible association with gastroschisis if used in first trimester; avoid due to vasoconstrictive effects.
First trimester: Limited human data; animal studies show embryotoxicity. Second/third trimester: May cause fetal hypoxia due to maternal hypotension; risk of preterm labor inhibition. Category C.
Ibuprofen: Excreted in low levels (M/P ratio ~0.006); considered compatible with breastfeeding. Pseudoephedrine: Excreted in breast milk (M/P ratio ~2.5-3.5); may reduce milk production and cause irritability in infants; use with caution.
Excreted in breast milk; M/P ratio ~0.85. Consider risks versus benefits; monitor infant for hypotension.
Ibuprofen: No specific dose adjustment recommended for pregnancy; however, avoid use in third trimester. Pseudoephedrine: No dose adjustment studied; use lowest effective dose for shortest duration. Neither drug is recommended for regular use during pregnancy.
No standard dose adjustment; monitor clinical response and blood pressure; may require lower doses due to vasodilation effects.
Combination of ibuprofen (NSAID) and pseudoephedrine (decongestant). Ibuprofen may increase blood pressure, counteracting pseudoephedrine's vasoconstriction; monitor in hypertensive patients. Avoid in patients with severe CAD, uncontrolled HTN, or within 2 weeks of MAOI use.
Adalat (nifedipine) is a dihydropyridine calcium channel blocker. Use immediate-release capsules only for hypertensive emergencies, not chronic treatment due to risk of reflex tachycardia and unpredictable hypotension. Extended-release formulations are preferred for stable angina and hypertension. Avoid grapefruit juice as it increases nifedipine levels via CYP3A4 inhibition. Monitor for peripheral edema, gingival hyperplasia, and constipation. Contraindicated in cardiogenic shock, severe aortic stenosis, and within 4 weeks of myocardial infarction.
