Medical student's apparent celiac disease responded to giardiasis treatment

I have this, how to kill it? I can't go to doctor, because they are all so difficult in my country when it comes to things like this. Does ivermectin help?

GPT and Drugs dot com both suggest individually trying these as needed: metronidazole/tinidazole, nitazoxanide, albendazole. I would try them only one at a time, not together. I fear that taking metronidazole and albendazole together might also risk SJS or some such adverse reaction. The doses of each are well known. Rifaximin is also commonly discussed in such circles, but it wasn't mentioned.

Even before these, I would try taking just 3g activated charcoal daily for up to a few days, but away from all medicines. It often (but not always) proves quite beneficial for me.

As for ivermectin, it won't hurt to try it, but we haven't established a connection of it to chronic giardisis.
