Certain medications like PPIs can suppress H. pylori temporarily, which may lead to a false-negative RUT result. Yes, PPI medicines should ideally be stopped at least 2 weeks before the endoscopy with RUT test for accurate results.
However, Famtac 40 (Famotidine) is an H2 blocker, not a PPI. It usually does not interfere significantly, but many doctors still advise stopping it 24–48 hours before the procedure if possible
Next Steps
Follow the fasting instructions given by the endoscopy center, usually 6–8 hours without food before the procedure.
