NURSING MOTHERS: It is not known if bumetanide is excreted into breast milk. Thus, it should be used in women who are breastfeeding only if its potential benefits outweigh the unknown risks.

SIDE EFFECTS: Potent diuretics like bumetanide can cause low blood levels of potassium, magnesium, sodium and calcium. Additionally, fluid loses can occur leading to dehydration. The symptoms of dehydration may include dry mouth, thirst, weakness, drowsiness, reduced kidney function, heart arrhythmias, muscle aches and pains, and/or nausea and vomiting.

Toxicity to the inner ear in the form of tinnitus (ringing in the ear) and hearing loss have been associated with loop diuretics. High plasma levels of bumetanide are toxic to the inner ear of animals. These effects on the inner ear are far more common with intravenous use of the drugs. High uric acid concentrations in the blood leading to attacks of gouty arthritis may occur during diuretic therapy.
