Abstract
Calcium channel blockers (CCBs) are widely prescribed medications for various clinical indications in adults and children. They are available in both immediate and long-acting formulations and are generally classified into dihydropyridines and nondihydropyridines, with nondihydropyridines having more cardioselectivity. CCB toxicity is common given the widespread use which leads to serious adverse clinical outcomes, especially in children. Severe CCB toxicities may present with life-threatening bradycardia, hypotension, hyperglycemia, and renal insufficiency. Dihydropyridine toxicity, however, may present with reflex tachycardia instead of bradycardia. Initial patient evaluation and assessment are crucial to identify the severity of CCB toxicity and design the best management strategy. There are different strategies to overcome CCB toxicity that requires precise dosing and close monitoring in various patient populations. These strategies may include large volumes of IV fluids, calcium salts, high insulin euglycemia therapy (HIET), and vasopressors. We hereby summarize the evidence behind the management of CCB toxicity and present a practical guide for clinicians to overcome this common drug toxicity.

Abstract
Such as any field of medicine, it is imperative to stay current with the latest advances and treatment modalities in toxicology. With the absence of rigorous randomized controlled trials, many updated guidelines are created by expert consensus and/or case reports and clinical experience. Over the past 10 years, there have been several changes in the management of drug overdoses in light of new data available. Although this is not a comprehensive review of all available antidotes, this article will focus on several important interventions including the use of gastrointestinal decontamination, hyperinsulinemic-euglycemic therapy, methylene blue, intravenous lipid emulsion, hemodialysis, and extracorporeal membrane oxygenation.
