Does Furosemide Benzalkonium Chloride Interact with Lithium?
CDI records a major classification for Furosemide Benzalkonium Chloride and Lithium. The stored summary is: Lithium should not be given with furosemide because diuretics reduce lithium's renal clearance and add a high risk of lithium toxicity. The mechanism involves reduced renal clearance of lithium. Patients taking both medications should consult their healthcare provider before starting, stopping, or changing the dosage of either drug. This record was extracted from drug labeling through openFDA. NIH/NLM RxNorm is used for drug identities. The summary and severity classification are CDI's processed information, not a verbatim source quotation. Product, route, and patient circumstances matter.

What To Tell Your Doctor or Pharmacist
If you are taking Furosemide Benzalkonium Chloride and your doctor is considering prescribing Lithium (or vice versa), make sure to:
- 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 how frequently you should be monitored while these are co-prescribed
- Ask whether any dosage adjustments are needed
- Never stop or change either medication without first consulting your healthcare provider
