Anti-inflammatory drugs usually refer to antibiotics, which should be prohibited 1 month before the review of H. pylori. The term anti-inflammatory drugs usually refers to antibiotics in general, such as penicillins (amoxicillin, etc.), cephalosporins (cefixime, ceftriaxone, etc.), aminoglycosides (streptomycin, gentamicin, etc.), macrolides (erythromycin, azithromycin, etc.), and tetracyclines (tetracycline, oxytetracycline, etc.). All of these antibiotics have a killing effect on H. pylori and may lead to false negative results, therefore, they should be prohibited 1 month before the review of H. pylori so as not to affect the test results. Patients should strictly follow the doctor’s instructions to make preparations before the H. pylori test to avoid affecting the test results. Once the test is found to be positive, it is recommended to seek timely medical treatment and carry out eradication treatment under the guidance of professional physicians.
