Last clinically reviewed: July 2026 · OpiCalc Medical Review Team
Partial agonist at mu-opioid receptors; also a weak antagonist at kappa-opioid receptors. Provides analgesic effects with reduced respiratory depression compared to full agonists.
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.
Management of moderate to severe chronic pain,Off-label: Treatment of opioid use disorder (as a maintenance therapy similar to buprenorphine)
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.
Adults: 200 mg orally twice daily with meals.
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.
Terminal elimination half-life is approximately 12-15 hours in patients with normal renal function, allowing for twice-daily dosing.
Ibuprofen: 2-4 hours; pseudoephedrine: 5-8 hours. Shorter half-life requires frequent dosing for sustained relief.
Primarily hepatic via CYP3A4 and CYP3A5 to norbuprenorphine (active metabolite); also undergoes glucuronidation.
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.
Approximately 60-80% of a dose is excreted renally as unchanged drug, with 20-40% eliminated via biliary/fecal routes.
Renal excretion of unchanged drug and metabolites; approximately 1% excreted unchanged (pseudoephedrine) and 15% (ibuprofen). Biliary/fecal elimination accounts for <5%.
Approximately 95-98% bound to plasma proteins, primarily albumin.
Ibuprofen: 99% bound to albumin; pseudoephedrine: negligible protein binding.
Volume of distribution is approximately 2-3 L/kg, indicating extensive tissue distribution beyond plasma volume.
Ibuprofen: 0.1-0.2 L/kg; pseudoephedrine: 2.5-3 L/kg.
Oral bioavailability is approximately 70-80%.
Oral: ibuprofen 80-100%; pseudoephedrine 100%.

No specific dose adjustment; monitor renal function and use caution due to increased risk of adverse effects.
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.
Risk of respiratory depression, especially in non-opioid-tolerant patients. Risk of neonatal opioid withdrawal syndrome with prolonged use during pregnancy. Risk of serious injury or death due to accidental exposure in children.
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.
Respiratory depression, particularly in the first 24-72 hours of treatment; caution in patients with pulmonary disease. Risk of QT prolongation. Adrenal insufficiency. Severe hypotension. Risk of misuse, abuse, and addiction. Tolerance and physical dependence.
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.
Hypersensitivity to buprenorphine or any component of the formulation. Severe respiratory insufficiency. Acute or severe bronchial asthma. Gastrointestinal obstruction, including paralytic ileus.
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).
No significant food interactions. Grapefruit juice may increase buprenorphine levels; avoid large quantities.
Take with food or milk to minimize GI upset. Avoid alcohol as it may increase risk of GI bleeding. No specific food-drug interactions.
Supr ENza (testosterone) is contraindicated in pregnancy due to virilization of female fetus. First trimester: high risk of clitoromegaly, labial fusion, and urogenital sinus abnormalities. Second and third trimesters: risk of continued virilization, including phallic enlargement and ambiguous genitalia. Fetal growth restriction may occur.
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.
Testosterone is present in breast milk; M/P ratio not reported. Avoid breastfeeding due to potential for androgenization of the infant. Use only if clearly needed and no safer alternative.
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.
Not applicable; Supr ENza is contraindicated in pregnancy. No dose adjustments are recommended as use is avoided entirely.
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.
SUPRENZA (buprenorphine/naloxone) sublingual film is used for opioid dependence. Monitor for respiratory depression especially when combined with benzodiazepines or alcohol. The naloxone component is poorly absorbed sublingually but precipitates withdrawal if injected. Administer only after clear signs of withdrawal to avoid precipitated withdrawal. Adjust dose in hepatic impairment as buprenorphine is hepatically metabolized.
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.
