Taking Mosapride does not usually affect the results of the Carbon 14 test. Carbon 14 test is a screening tool to detect whether you are infected with Helicobacter pylori by blowing after taking a nuclide-labeled pill orally, which is highly effective, safe, easy and comfortable. Acid-suppressing drugs such as omeprazole and ranitidine, antibiotics such as amoxicillin and tetracycline, bismuth such as bismuth pectin and bismuth potassium citrate, as well as proprietary Chinese medicines such as Rehabilitation New Liquid, etc., can affect the test results. Mosapride is a gastric stimulant that promotes gastrointestinal motility and improves dyspeptic symptoms by increasing the release of acetylcholine. This drug generally does not affect the number and distribution of Helicobacter pylori, nor does it affect the carbon 14 nuclide-labeled pills, so it generally does not affect the carbon 14 test results. Take care to use the drug under the supervision of a physician. It is contraindicated in patients who are allergic to the product, those with bleeding and perforation of the gastrointestinal tract, intestinal obstruction, patients with hepatic or renal insufficiency, those with a history of heart disease such as heart failure, conduction block, ventricular arrhythmia, patients with electrolyte disorders, and those who have recently undergone intestinal surgery. Adverse reactions such as diarrhea, abdominal pain and dizziness may occur.
