Magnesium Sulfate-Induced Anaphylaxis: A Case Report and Review of the Literature.

Anaphylaxis due to magnesium sulfate is uncommon with very few reported cases. We report a case of a 28-year-old female who had low serum magnesium and was given magnesium sulfate. She developed pruritic urticarial rash, hypoxemia, and stridor. Anaphylaxis was diagnosed, and she received epinephrine, diphenhydramine, and oxygen therapy causing resolution. The study also discusses similar published cases and their presentation and treatment. We have briefly overviewed the clinical criteria for the diagnosis of anaphylaxis. The study also intends to make the clinician consider anaphylaxis while administering magnesium sulfate for any reason.
