When the drug interacts with aminoglycosides, the process of their excretion from the body slows down, and this leads to an increase in the ototoxicity and nephrotoxicity of the preparations of this group.

Furosemide reduces the therapeutic effect of hypoglycemic drugs, which should be taken into account and adjusted to people with diabetes the dosage of insulin and hypoglycemic drugs.
