BACKGROUND- Tensilon (edrophonium chloride) is a reversible acetylcholinesterase inhibitor used in the diagnosis of myasthenia gravis, diagnosis and treatment of arrhythmias, detection of early digitalis toxicity, reversal of neuromuscular blockade, and other medical conditions. Toxicity associated with Tensilon use has appeared in the literature for decades. REVIEW SUMMARY- This review discusses the risks of Tensilon and the information practitioners should know before administering the drug. We review the literature regarding serious toxicity of this drug and offer recommendations for its safe use. CONCLUSIONS- A careful medication history should be taken before the administration of Tensilon. Additionally, physicians should be aware of appropriate alternative methods of diagnosis before choosing to administer Tensilon. Physicians should be aware of the clinical situations where the Tensilon test no longer is indicated.
