In premature infants LASIX may precipitate nephrocalcinosis/nephrolithiasis.
If LASIX is administered to premature infants during the first weeks of life, it may increase the risk of persistence of patent ductus arteriosus.
Whenever adverse reactions are moderate or severe, LASIX dosage should be reduced or therapy withdrawn.
