If all the gastritis drugs taken are vomited out, it is recommended to adjust the dose of the drug, you can start with the smallest amount, if still can not be relieved can also be changed to the infusion of drugs, so that the condition will be significantly better, you can also add antiemetic drugs to reduce the adverse effects of drugs, so that the symptoms of nausea and vomiting do not occur easily. The vomiting of drugs for gastritis needs to be clearly diagnosed in addition to the application of drugs. If there are liver function abnormalities and electrolyte disorders, taking gastritis drugs alone cannot relieve them. Some patients with abnormal kidney function and heart failure can also have significant vomiting and upper gastrointestinal symptoms, but taking gastritis drugs cannot relieve them either.
