Specific Bumex Warnings and PrecautionsWarnings and precautions to be aware of prior to taking Bumex include the following:
- If kidney problems seem to be getting worse (especially for those with severe kidney disease), Bumex should be stopped because the medicine can make kidney problems worse.
- Bumex can cause hearing loss. Sometimes, this hearing loss is permanent. It is more common when high doses of the drug are given intravenously or when combined with other medications that can cause hearing loss.

This is why it is important to drink fluids regularly while taking the drug. If you have any possible symptoms of low blood pressure, such as dizziness, lightheadedness, or fainting, contact your healthcare provider. If you have fainted, stop taking Bumex until you have talked to your healthcare provider.
