Digitalizing dose: 0.01-0.02 mg/kg IV or IM, given in divided doses over 24 hours. Maintenance: 10-20% of digitalizing dose daily. Not recommended for neonates due to prolonged half-life.
0.1-0.2 mg/kg IV/IM/SC every 3-6 hours as needed; maximum single dose 20 mg.
Reduce dose by 25-50% due to decreased renal function and increased sensitivity. Monitor serum levels and renal function closely.
Initiate at 50% of adult dose (5-10 mg) and titrate cautiously due to increased sensitivity and risk of respiratory depression.
Can cause potentially fatal arrhythmias; use only when clearly indicated and monitor serum levels.
Risk of respiratory depression, abuse, misuse, and addiction; concomitant use with benzodiazepines or CNS depressants may cause profound sedation, respiratory depression, coma, and death; neonatal opioid withdrawal syndrome with prolonged use during pregnancy.
Narrow therapeutic index; toxicity risk increased with hypokalemia, hypomagnesemia, hypercalcemia, renal impairment; monitor ECG and drug levels.
Respiratory depression; abuse potential; neonatal opioid withdrawal syndrome; adrenal insufficiency; severe hypotension; head injury and increased intracranial pressure; severe hepatic or renal impairment.
Ventricular fibrillation, digitalis toxicity, hypersensitivity, AV block (unless pacemaker present), Wolff-Parkinson-White syndrome.
Hypersensitivity to nalbuphine or any component; significant respiratory depression; acute or severe bronchial asthma; paralytic ileus; suspected or known gastrointestinal obstruction; use of MAOIs within 14 days.
Avoid licorice, which can cause hypokalemia. Maintain consistent intake of potassium-rich foods (bananas, oranges) to avoid fluctuations. No known significant food interactions beyond electrolyte effects.
No specific food interactions. Avoid grapefruit juice as it may theoretically increase nalbuphine levels (CYP3A4 substrate, though major metabolism via glucuronidation). Maintain adequate hydration to prevent constipation.
Pregnancy Category C. First trimester: No adequate human studies; animal studies show fetal risk. Second/third trimester: Risk of fetal bradycardia, cardiac glycoside toxicity; avoids if possible.
Pregnancy Category C. No adequate well-controlled studies in pregnant women. Animal studies have shown no teratogenic effects but embryocidal effects at high doses. Use only if potential benefit justifies risk. In first trimester, avoid unless necessary. Second and third trimesters: risk of neonatal respiratory depression, withdrawal if chronic use. Near term: may prolong labor and cause neonatal respiratory depression.
Deslanoside is excreted in breast milk; estimated infant dose 0.1-0.5% of maternal weight-adjusted dose; M/P ratio not well defined. Monitor infant for bradycardia, feeding difficulties; benefit likely outweighs risk.
Excreted in breast milk in small amounts; M/P ratio approximately 0.47-1.5. Limited data; caution recommended. Monitor infant for sedation and respiratory depression. Benefits of breastfeeding should outweigh risks.
Increased renal clearance in pregnancy may require higher doses; monitor serum drug levels and adjust accordingly. Reduced dosing in third trimester may be needed due to volume expansion.
No specific dose adjustment recommended for pregnancy, but pharmacokinetics may be altered due to increased volume of distribution and clearance. Dosing should be on an individual basis, titrated to effect. Use lowest effective dose and shortest duration. During labor, doses should be reduced due to potential for respiratory depression in neonate.
Cedilanid-D (deslanoside) is a rapidly acting parenteral digitalis glycoside. Use with extreme caution in renal impairment due to reduced clearance. Monitor serum potassium and magnesium; hypokalemia and hypomagnesemia potentiate toxicity. Administer slow IV push over 5 minutes to avoid arrhythmias. Therapeutic drug monitoring less common due to short half-life of 33 hours. Contraindicated in ventricular tachycardia and AV block (unless due to atrial fibrillation).
Nalbuphine is a mixed agonist-antagonist opioid with ceiling effect on respiratory depression; less abuse liability than morphine. Useful for opioid-induced pruritus (e.g., with morphine) at low doses (0.1 mg/kg IV). May precipitate withdrawal in opioid-dependent patients. Avoid in opioid-tolerant patients on full agonists. Metabolized by liver; adjust dose in hepatic impairment. Not a controlled substance (US), but report to regulatory authorities as required.
Take exactly as prescribed; do not double doses.,Report symptoms of toxicity: nausea, vomiting, visual disturbances (yellow-green halos), irregular heartbeat.,Avoid over-the-counter medications without consulting doctor.,Maintain consistent potassium intake; avoid high-potassium foods or supplements unless advised.,Monitor daily weight and report rapid weight gain or edema.
Take exactly as prescribed; do not increase dose or frequency without consulting your doctor.,May cause drowsiness, dizziness, or blurred vision; avoid driving or operating machinery until you know how nalbuphine affects you.,Avoid alcohol and other CNS depressants (e.g., benzodiazepines, sedatives) as they increase risk of severe drowsiness, respiratory depression, coma, or death.,Do not stop suddenly after prolonged use; withdrawal symptoms may occur but are generally milder than with full agonists.,Report any signs of allergic reaction (rash, hives, swelling) or difficulty breathing immediately.,If you have been taking other opioids, inform your doctor to avoid withdrawal symptoms.,Store at room temperature away from heat, light, and moisture; keep out of reach of children.
No interactions on record
"The combination of trifluoperazine, a phenothiazine antipsychotic, with nalbuphine, a mixed opioid agonist-antagonist, can lead to additive central nervous system (CNS) depression, including increased sedation, respiratory depression, and hypotension. Trifluoperazine may enhance the depressant effects of nalbuphine on the brainstem respiratory centers and vasomotor centers. Clinically, this interaction may result in excessive sedation, respiratory compromise, and orthostatic hypotension, particularly in elderly or debilitated patients."
"Combined use of nalbuphine, a mixed opioid agonist-antagonist, with entacapone, a catechol-O-methyltransferase (COMT) inhibitor, may increase the risk of opioid-related adverse effects, including respiratory depression and sedation, due to additive central nervous system depression. Entacapone can also inhibit the metabolism of catecholamines, potentially exacerbating opioid-induced constipation and urinary retention. Clinically, patients may experience enhanced sedation or respiratory compromise, particularly in elderly or debilitated populations."
"Concomitant use of clozapine and nalbuphine may potentiate central nervous system (CNS) depression, leading to additive sedative and respiratory depressant effects. Both drugs act on the CNS via distinct mechanisms but converge on common pathways, increasing the risk of hypotension, bradycardia, and profound sedation. Clinically, patients may experience excessive drowsiness, confusion, or respiratory compromise, particularly in those with pre-existing comorbidities or concurrent use of other CNS depressants."
