Hi,
I finished my treatment of antibiotics 3 months ago and PPI 3 weeks ago for H.pylori but I did not made a breath test yet.
3 days ago I took an antibiotics (Bactrim) because of a severe diarrhea so my question is :
do I have to wait 1 month before doing the breath test because taking of this antibiotics or I can do it anytime ?

unfortunately you'll need to wait at least 2 weeks before the follow up breath test.

so I don't have to take any antibiotics for a while before the breath test ?

yup. the breath test is dependent on two things. one is bacterial load and second is an acidic stomach. If you take any thing (including antibiotiocs) that can reduce the bacterial load or the stomach acid (such as PPI), then the test wont work.
