Does Indomethacin Interact with Bumetanide?

Indomethacin and Bumetanide have a contraindicated drug interaction according to U.S. FDA drug labeling data. Concurrent therapy with indomethacin is not recommended as it blunts bumetanide-induced increases in urine volume, sodium excretion, and plasma renin activity. The mechanism involves inhibition of bumetanide natriuresis and renin activity increase. Patients taking both medications should consult their healthcare provider before starting, stopping, or changing the dosage of either drug. This information is based on official FDA drug labeling sourced from OpenFDA and the NIH National Library of Medicine.

  • Inform your doctor and pharmacist of all current medications, including over-the-counter drugs and supplements
  • Ask whether the benefits of combining these medications outweigh the risks for your specific situation
  • Ask what symptoms to watch for that would indicate the interaction is causing problems
  • Ask about alternative medications that do not interact with your current regimen
  • Ask how frequently you should be monitored while these are co-prescribed
