Nitrofurantoin

From SNPedia

Nitrofurantoin, sold under the trade name Macrobid and Furadantin among others, is an antibiotic used to treat bladder infections; however, it is not effective for kidney infections.Wikipedia

The FDA-approved label for Furadantin includes a warning that cases of hemolytic anemia of the primaquine-sensitivity type have been induced by nitrofurantoin, presumably due to G6PD-deficiencies as have been linked to primaquine. Hemolysis is an indication for discontinuing Furadantin.
