Drug Interactions between morphine liposomal and torsemide

Consumer information for this interaction is not currently available.

MONITOR: Opioids exhibit hypotensive effects, especially during initiation of therapy and dose escalation. Coadministration with diuretics may lead to an increased risk of hypotension. In contrast, opioids may also decrease the efficacy of diuretics as they may trigger the secretion of antidiuretic hormone, although the proposed mechanism for this interaction is unclear and clinical studies are not currently available.

MANAGEMENT: Caution and close monitoring for development of hypotension in addition to decreased diuretic efficacy are advised during coadministration of these agents. Blood pressure should be monitored throughout therapy and dose adjustment of the diuretic should be considered. Patients should be advised to avoid rising abruptly from a sitting or recumbent position and to notify their physician if they experience dizziness, lightheadedness, syncope, orthostasis, or tachycardia. Patients should also avoid driving or operating hazardous machinery until they know how the medications affect them.
