Case of Leukotriene Receptor Antagonist Related Bradycardia in Patient Taking Montelukast

Abstract

A 74-year-old male on Montelukast presented initially with tachycardia in septic shock masking his underlying bradycardia, which emerged with initiation of sepsis treatment. The patient’s heart rate responded to cessation of Montelukast showing a likely association between Montelukast and bradycardia. Further research is necessary to thoroughly investigate this relationship.
