Nitrofurantoin and MGUS / multiple myeloma?

by kayleen on Sat Aug 04, 2018 4:19 pm

Does anyone know if there is any link between the anti­biotic nitro­furantoin (Macro­dantin, Macro­bid) and MGUS or multiple myeloma?

I used Macrodantin for five years and developed an auto­immune disease in my body which had many of the same symp­toms that brought me to the neurologist this time to find out I have poly­neuropathy with IgM MGUS with lambda light chains.

Hum, that's a great question. I was also on Macrodantin (nitrofurantoin) for chronic kidney in­fections. Not quite as long as you, maybe a year or two. I also have IgM MGUS that caused cold agglutinin, rouleaux, and hemolysis.

I have taken Macrobid (nitro­furantoin) for many years for chronic urinary tract infections. I have IgG lambda MGUS. I take it as a preventative measure after I'm sexually intimate. Should I ask my hematologist-oncologist if this is okay?
