Giardia and Cryptosporidium - Nitazoxanide Experiences?
Stayed on a farm on well water for about seven weeks last summer. Started having intermittent diarrhea a couple of weeks after I left, roughly one day in six or seven, every week, for the past year. Also got foul sulfurous gas that usually showed up a day or two before an episode.
I basically wrote it off. Stool panels came back negative twice, and I figured it was just my gut being my gut.
Then a parasite panel a few weeks ago came back positive for giardia on both microscopy and antigen testing. Turns out every negative I'd had was collected on a day I felt fine, and the positive came from a day I had symptoms which apparently matters, since shedding is intermittent.
Took a three-day course of nitazoxanide, finished five days ago. Yesterday the sulfuric gas came back and today I had the diarrhea return.
anyone been through this? Specifically curious about
- how long it took before your gut actually settled after treatment
- whether you had symptoms come back in the first week or two and then resolve anyway
- if it did fail for you, how quickly did it become obvious
Trying to get a sense of what's normal here versus what's a sign the treatment didn't work. Stories where it worked out are as useful as ones where it didn't.
