Whenever anticholinesterase drugs are used for testing, a syringe containing 1 mg of atropine sulfate should be immediately available to be given in aliquots intravenously to counteract severe cholinergic reactions which may occur in the hypersensitive individual, whether he is normal or myasthenic. Enlon (edrophonium injection) ® should be used with caution in patients with bronchial asthma or cardiac dysrhythmias. The transient bradycardia which sometimes occurs can be relieved by atropine sulfate. Isolated instances of cardiac and respiratory arrest following administration of Enlon (edrophonium injection) ® have been reported. It is postulated that these are vagotonic effects.

Contains sodium sulfite, a sulfite that may cause allergic-type reactions including anaphylactic symptoms and life-threatening or less severe asthmatic episodes in certain susceptible people. The overall prevalence of sulfite sensitivity in the general population is unknown and probably low. Sulfite sensitivity is seen more frequently in asthmatic than in nonasthmatic people.

Usage in Pregnancy: The safety of Enlon (edrophonium injection) ® during pregnancy or lactation in humans has not been established. Therefore, use of Enlon (edrophonium injection) ® in women who may become pregnant requires weighing the drug†s potential benefits against its possible hazards to mother and child.


Patients may develop †anticholinesterase insensitivity¬Ě for brief or prolonged periods. During these periods the patients should be carefully monitored and may need respiratory assistance. Dosages of anticholinesterase drugs should be reduced or withheld until patients again become sensitive to them.

This monograph has been modified to include the generic and brand name in many instances.
