Calcium Channel Blocker Overdose With Cardiogenic Shock.

Calcium channel blocker (CCB) overdose is a rare but potentially life-threatening presentation associated with profound bradycardia, shock, and metabolic disturbances. Management can be complex, often requiring advanced hemodynamic support and multimodal therapies. We report a case of severe CCB intoxication leading to refractory hypotension, illustrating the challenges encountered in critical care management. Current approaches involve multimodal pharmacological interventions, including high-dose insulin euglycemic therapy, IV calcium, glucagon, and lipid rescue. CCBs have widespread use; therefore, understanding the consequences of overdose is clinically important.
