Clinician-reviewed, head-to-head comparison of mechanism, dosing, pharmacokinetics, and safety profiles.
Last clinically reviewed: July 2026 · OpiCalc Medical Review Team
Bumetanide inhibits the Na-K-2Cl symporter (NKCC2) in the thick ascending limb of the loop of Henle, reducing reabsorption of sodium, chloride, and potassium, leading to increased diuresis.
Acetaminophen: analgesic and antipyretic effects via inhibition of cyclooxygenase (COX) and activation of descending serotonergic pathways; central action. Hydrocodone: mu-opioid receptor agonist; activates G-protein coupled receptors to modulate pain perception and emotional response.
Edema associated with congestive heart failure,Edema associated with hepatic cirrhosis,Edema associated with renal disease including nephrotic syndrome
Moderate to moderately severe pain,Cough suppression (hydrocodone; off-label)
0.5-2 mg orally once daily; if inadequate response, may increase to 2-4 mg once daily or twice daily. Maximum 10 mg/day. IV: 0.5-1 mg IV over 1-2 minutes; may repeat every 2-3 hours up to 10 mg/day.
1-2 tablets (containing 5-10 mg hydrocodone and 300-325 mg acetaminophen) orally every 4-6 hours as needed for pain; maximum 8 tablets per day.
Terminal elimination half-life: 1.5–2 hours in normal renal function; prolonged to 2.5–4 hours in severe renal impairment (Cr Cl <20 m L/min).
Acetaminophen: 2-3 hours in adults; prolonged in hepatic impairment (up to 5 hours). Hydrocodone: 3.8-4.5 hours (range 3-5 hours) in healthy adults; prolonged in elderly or hepatic/renal impairment. Clinical context: repeated dosing may require extended intervals in renal impairment.
Primarily metabolized by the liver via cytochrome P450 enzymes, including CYP2C9 and CYP3A4.
Acetaminophen: primarily via glucuronidation (UGT1A1, UGT1A6, UGT1A9) and sulfation; minor CYP2E1 oxidation to NAPQI (toxic metabolite). Hydrocodone: CYP3A4 and CYP2D6; N-demethylation to norhydrocodone; O-demethylation to hydromorphone (CYP2D6).
Renal: 80% as unchanged drug; biliary/fecal: 15% as metabolites; total renal elimination accounts for ~85% of clearance.
Acetaminophen: primarily renal excretion of conjugated metabolites (glucuronide and sulfate) with approximately 5% excreted unchanged. Hydrocodone: renal excretion as unchanged drug and metabolites (O-demethylated and N-demethylated); total renal excretion accounts for about 60-70% of dose (parent and metabolites). Biliary/fecal elimination is minimal.
Bumetanide is 94–96% bound to plasma proteins (primarily albumin).
Acetaminophen: 10-25% bound, nonspecific binding to albumin. Hydrocodone: 25-50% bound, primarily to albumin and alpha-1-acid glycoprotein.
0.15–0.22 L/kg; indicates primarily extracellular distribution.
Acetaminophen: 0.8-1.0 L/kg, indicating distribution into total body water; clinically relevant for loading dose calculations. Hydrocodone: 3.0-4.0 L/kg, suggesting extensive tissue distribution; higher Vd may require higher loading doses but has no clinical target.
Oral bioavailability: 80–100% (mean ~95%).
Acetaminophen: oral bioavailability 85-95% (first-pass metabolism minimal). Hydrocodone: oral bioavailability about 25-45% due to first-pass hepatic metabolism; significant interindividual variability.
e GFR <20 m L/min/1.73 m²: Avoid loop diuretics; consider alternative. No adjustment for mild to moderate renal impairment, but monitor response. In severe renal failure, may require higher doses due to reduced tubular secretion.
GFR 10-50 m L/min: administer every 6 hours; GFR <10 m L/min: administer every 8 hours; avoid in severe impairment due to acetaminophen metabolite accumulation.
Child-Pugh Class B or C: Reduce initial dose by 50% due to impaired metabolism and increased risk of volume depletion. Titrate cautiously.
Child-Pugh A: no adjustment; Child-Pugh B: reduce dose by 50% or extend interval; Child-Pugh C: use with caution, avoid if possible, consider alternative therapy.
Infants/Children: Oral: 0.015-0.1 mg/kg/dose once daily; maximum 10 mg/day. IV/IM: 0.015-0.1 mg/kg/dose every 12-24 hours; maximum 0.5 mg/kg/dose. Neonates: 0.01-0.05 mg/kg/dose every 24-48 hours.
Dosing based on hydrocodone component: 0.1-0.2 mg/kg/dose every 4-6 hours; maximum daily acetaminophen limit: 75 mg/kg/day; not recommended for children <2 years.
Start at 0.5 mg orally once daily; increase cautiously due to enhanced pharmacodynamic effects and higher risk of electrolyte disturbances, volume depletion, and ototoxicity. Monitor renal function and electrolytes closely.
Initiate at lowest effective dose, typically 1 tablet (2.5-5 mg hydrocodone) every 6 hours; monitor for respiratory depression and acetaminophen toxicity; avoid in frail elderly with hepatic impairment.
Bumetanide is a potent diuretic; if given in excessive amounts, can lead to profound diuresis with water and electrolyte depletion. Therefore, careful medical supervision is required, and dose and dosage schedule must be adjusted to individual patient's needs.
Addiction, abuse, and misuse; life-threatening respiratory depression; accidental ingestion of acetaminophen; neonatal opioid withdrawal syndrome; interaction with alcohol; risk of medication errors.
Electrolyte depletion (hypokalemia, hyponatremia, hypochloremia),Dehydration and hypovolemia,Ototoxicity (especially with rapid injection or in renal impairment),Excessive diuresis causing hypotension and thromboembolic events,May increase serum uric acid levels and precipitate gout,Risk of hypokalemia in patients with cirrhosis and ascites
Hepatotoxicity from acetaminophen overdose; respiratory depression; increased intracranial pressure; CNS depression; elderly/debilitated patients; renal impairment; opioid-induced hyperalgesia; serotonin syndrome; interaction with CNS depressants; risk of adrenal insufficiency; severe hypotension; use in patients with gastrointestinal obstruction; convulsion risk; severe hepatic impairment; urinary retention; acute abdominal conditions; hypothyroidism; prostatic hypertrophy; adrenocortical insufficiency; pregnancy/lactation; pediatric use; geriatric use; renal impairment; hepatic impairment.
Anuria,Hepatic coma or severe electrolyte depletion until condition is corrected,Hypersensitivity to bumetanide or sulfonamides (cross-sensitivity possible)
Hypersensitivity to acetaminophen or hydrocodone; significant respiratory depression; acute or severe bronchial asthma; upper airway obstruction; known or suspected gastrointestinal obstruction; paralytic ileus; concomitant use of monoamine oxidase inhibitors (MAOIs) or within 14 days; severe hepatic impairment (acetaminophen toxicity risk); acute alcoholism.
Avoid excessive salt intake; no specific food interactions reported. Avoid licorice as it may worsen hypokalemia. Grapefruit juice may increase bumetanide levels; use caution.
Avoid alcohol consumption during therapy; ethanol increases acetaminophen hepatotoxicity risk and enhances CNS depression. Grapefruit juice may inhibit CYP2D6 (minor effect) but no significant clinical interaction. No other specific food restrictions.
Bumetanide (BUMEX) is a loop diuretic classified as FDA Pregnancy Category C. Animal studies have shown embryocidal effects and delayed ossification at high doses. Human data are limited; no well-controlled studies exist. First trimester: theoretical risk based on animal data; avoid unless essential. Second/third trimesters: may cause maternal hypovolemia, decreased placental perfusion, and fetal oliguria; use only if clearly needed and monitor amniotic fluid volume. Neonatal risks include electrolyte imbalances and ototoxicity if used close to delivery.
First trimester: Acetaminophen considered low risk; hydrocodone is a pregnancy category C drug. Data from retrospective studies suggest a small increased risk of certain congenital malformations (e.g., neural tube defects, cleft palate) with first trimester opioid use, but absolute risk is low. Second trimester: Low risk as above. Third trimester: Prolonged use of hydrocodone can cause neonatal opioid withdrawal syndrome (NOWS); acetaminophen is safe. Use only if benefit outweighs risk.
Bumetanide is excreted into human milk in low concentrations. The milk-to-plasma (M/P) ratio is approximately 0.05-0.10. Based on limited data, amounts ingested by breastfed infants are unlikely to cause adverse effects. However, due to potential risk of hypersensitivity, electrolyte disturbances, or diuresis in the infant, caution is advised, especially in premature or renal-impaired infants. Alternative diuretics with more safety data may be preferred.
Acetaminophen excretion in breast milk is low (M/P ratio ~0.9). Hydrocodone is excreted in small amounts (M/P ratio ~2.1). The relative infant dose is estimated to be 2.5-3.5% of maternal weight-adjusted dose for hydrocodone. Monitor infant for sedation and respiratory depression. Consider benefit to mother and potential neonatal opioid withdrawal if used chronically.
Pregnancy may alter bumetanide pharmacokinetics due to increased plasma volume, renal blood flow, and glomerular filtration rate. Higher doses may be required to achieve the same diuretic effect. However, no standard dose adjustment guidelines exist; use the lowest effective dose and titrate based on clinical response, monitoring for electrolyte disturbances and volume depletion. In severe preeclampsia or renal impairment, dose may need reduction. Close therapeutic drug monitoring is not routinely available; clinical monitoring of diuresis and electrolytes guides dosing.
During pregnancy, increased plasma volume and enhanced hepatic clearance may reduce serum concentrations of both drugs. However, dosing adjustments are not routinely recommended due to risk of undertreatment. Use the lowest effective dose of hydrocodone for the shortest duration. For acetaminophen, maximum daily dose should not exceed 3000 mg to avoid hepatotoxicity.
Bumetanide is a loop diuretic approximately 40 times more potent than furosemide; onset of diuresis within 30-60 minutes after oral administration. Monitor for ototoxicity, especially with rapid IV administration or concurrent use of other ototoxic drugs. Hypokalemia is a common adverse effect; consider potassium supplementation or concurrent use of potassium-sparing diuretics. Contraindicated in anuria, hepatic coma, and severe electrolyte depletion. May cause hyperuricemia and precipitate gout attacks.
Acetaminophen-hydrocodone is contraindicated in severe respiratory depression, acute or severe bronchial asthma, and known hypersensitivity. Monitor for respiratory depression, especially in elderly or debilitated patients. Avoid use with other acetaminophen-containing products to prevent hepatotoxicity. Hydrocodone is a prodrug metabolized by CYP2D6 to hydromorphone; CYP2D6 ultrarapid metabolizers may experience toxicity. Use with caution in patients with head injury, increased intracranial pressure, or severe hepatic impairment. Naloxone is the reversal agent for opioid effects; acetylcysteine for acetaminophen overdose.

No interactions on record
"Hydrocodone, an opioid agonist, and scopolamine, an anticholinergic agent, both exhibit central nervous system (CNS) depressant effects. When co-administered, their combined activity can lead to additive CNS depression, resulting in enhanced sedation, respiratory depression, and cognitive impairment. This interaction may also increase the risk of constipation and urinary retention due to additive anticholinergic effects from both drugs."
"Pargyline, a monoamine oxidase inhibitor (MAOI), irreversibly inhibits the metabolism of amines, leading to increased intraneuronal stores of norepinephrine. Hydrocodone, a semisynthetic opioid, can release these stored catecholamines, potentially causing a hypertensive crisis, serotonin syndrome, or CNS excitation. Coadministration may also result in excessive sedation and respiratory depression due to additive CNS depressant effects, requiring immediate clinical attention."
"Hydrocodone, an opioid agonist, and oxprenolol, a non-selective beta-adrenoceptor antagonist, are both central nervous system (CNS) depressants. Their combined use can lead to additive CNS depression, resulting in excessive sedation, respiratory depression, hypotension, and bradycardia. This interaction is particularly dangerous in patients with compromised cardiac or respiratory function, potentially leading to coma or death."
