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.
Opioid agonist; binds to mu-opioid receptors in the CNS, altering pain perception and response.
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.
Management of breakthrough pain in cancer patients aged 16 and older who are already receiving and tolerant to opioid therapy for their underlying persistent cancer pain
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.
200 mcg transmucosally, titrated upward as needed; initial dose for opioid-tolerant patients is 200 mcg, with additional doses possible after 15 minutes if needed. Maximum 4 doses per episode. At least 4 hours between episodes.
Ibuprofen: 2-4 hours; pseudoephedrine: 5-8 hours. Shorter half-life requires frequent dosing for sustained relief.
Terminal half-life 0.83–2 hours (mean 1.3 h) in adults; note that context: transmucosal absorption leads to rapid onset but short duration; half-life is not correlated with clinical effect due to oral transmucosal route and rapid redistribution.
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.
Primarily hepatic via CYP3A4 to inactive metabolites (norfentanyl, despropionylfentanyl, hydroxyfentanyl) and other metabolites; <7% excreted unchanged in urine.
Renal excretion of unchanged drug and metabolites; approximately 1% excreted unchanged (pseudoephedrine) and 15% (ibuprofen). Biliary/fecal elimination accounts for <5%.
Primarily renal as metabolites (about 75% as metabolites, <10% unchanged). Fecal excretion accounts for <9%. Biliary excretion is minor.
Ibuprofen: 99% bound to albumin; pseudoephedrine: negligible protein binding.
Fentanyl is 80–85% bound to plasma proteins (primarily albumin and α1-acid glycoprotein).
Ibuprofen: 0.1-0.2 L/kg; pseudoephedrine: 2.5-3 L/kg.
Approximately 4 L/kg (range 3–6 L/kg); large Vd indicates extensive tissue distribution and redistribution contributing to short duration.
Oral: ibuprofen 80-100%; pseudoephedrine 100%.
Oral transmucosal: 50% (range 47–54%) relative to IV; variable and enhanced by rapid absorption through buccal mucosa.
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 specific GFR-based dose adjustment recommended; use with caution in severe renal impairment (Cr Cl < 30 m L/min) and consider dose reduction due to potential accumulation.
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/B: No adjustment. Child-Pugh Class C: Reduce initial dose to 100 mcg and titrate slowly; monitor closely for prolonged effects.
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.
Not approved for pediatric use; safety and efficacy not established in patients under 16 years.
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.
Initiate at 100 mcg transmucosally; titrate slowly due to increased sensitivity and risk of respiratory depression. Monitor for adverse effects.
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.
Risk of respiratory depression, addiction, abuse, and misuse; accidental ingestion can be fatal; concomitant use with benzodiazepines or CNS depressants may cause profound sedation, respiratory depression, coma, and death; not for use in opioid non-tolerant patients; risk of neonatal opioid withdrawal syndrome with prolonged use during pregnancy; serious, life-threatening, or fatal respiratory depression may occur even at recommended doses.
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.
Risk of respiratory depression; addiction, abuse, and misuse; interactions with CNS depressants; serotonin syndrome; adrenal insufficiency; severe hypotension; seizures; withdrawal; use in patients with head injuries, increased intracranial pressure, biliary tract disease, pancreatitis; risk of choking with lozenge; oral mucosal irritation; dental caries; hypokalemia; hyponatremia; use in elderly, cachectic, or debilitated patients.
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).
Significant respiratory depression; acute or severe bronchial asthma in an unmonitored setting or without resuscitative equipment; known or suspected paralytic ileus; hypersensitivity to fentanyl or any component; opioid non-tolerant patients; management of acute or postoperative pain including headache/migraine, dental pain, or emergency department use.
Take with food or milk to minimize GI upset. Avoid alcohol as it may increase risk of GI bleeding. No specific food-drug interactions.
No significant food interactions. Grapefruit juice may increase fentanyl levels, but specific studies with ACTIQ are lacking. Avoid alcohol, as it may increase sedation and respiratory depression risk.
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.
FDA Pregnancy Category C. First trimester: limited human data; animal studies show increased resorptions and fetal growth restriction. Second/third trimester: chronic use may cause neonatal opioid withdrawal syndrome; avoid use during labor due to risk of neonatal respiratory depression.
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 not established. Limited data suggest low levels, but risk of infant sedation and respiratory depression. Avoid use while breastfeeding unless potential benefit outweighs risk.
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.
Due to increased plasma volume and hepatic metabolism in pregnancy, dose requirements may increase; adjust based on clinical response and tolerance. Avoid use during labor and delivery due to risk of neonatal respiratory depression; short-term use preferred.
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.
ACTIQ is a transmucosal immediate-release fentanyl formulation indicated for breakthrough cancer pain in opioid-tolerant patients. Initiate with the lowest strength (200 mcg) and titrate upward. Avoid use in opioid-naive patients due to risk of fatal respiratory depression. Place the unit between cheek and lower gum, not sublingually. Instruct patient not to bite or suck the unit.
