Abstract: Objective To explore serious allergic reactions caused by hydrotalcite chewable tablets so as to provide a reference for clinical practice. Methods One case was analyzed in which hydrotalcite chewable tablets were used after surgery to prevent severe allergic reactions caused by digestive tract injury. The mechanism of occurrence, clinical manifestations, and treatment of sub-adverse reactions were investigated based on literature. Results Correlation analysis found that there was a close relationship between the time this adverse reaction occurred and the time of medication. The adverse reaction was classified as a grade II severe allergic reaction. This patient’s symptoms improved after treatment with anti-allergy drugs, blood pressure elevation and rehydration. Conclusion Clinicians should be alert to severe allergic reactions caused by hydrotalcite chewable tablets. The related mechanism remains elusive and more studies are needed.
