Howdy,

About a year ago I was diagnosed with Nitrofaurintin toxicity.

Due due a bladder condition I intermittently catheter 4/5 times a day so preventive antibiotics are pretty much a daily med.

In 2020 Trimethroprine became hard to get so my urology dude switched me to Natroforuntan and it worked really well in keeping uti under control.

I am a 69 year old life long high performance cyclist/ultra runner/ athlete and beginning cyclocross season last fall I realized I could not get my lungs to expand, couldn’t get heart up, could not supply oxygen and felt constricted in my lung expansion.

Went to my GP and he said long covid I did some research and came up with toxicity issues related to Natroforuntan.

Got appointment with pulmonologist, x rays, Ct scan etc confirmed scarring and nodule.

Immediately stopped that anti biotic, switched to trimethroprine and within 6 weeks started improving, at 6 months I’ve been released by pulmonologist.

At 6 weeks post stopping natro my pft results were 120%_150% of”normal “

So my urologist said I was first person he ever encountered with toxicity to that type of anti biopics, a pharmacy friend I talked to never heard of it, my go said no way it was s problem.

So self research and educating yourself is critical.

This forum helps answer questions.

I hope this reply helps and gives hope that stopping this type of antibiotic can many times reverse damage caused if scarring is related directly to this and not another cause.
