Enlon (edrophonium injection) is a short and rapid-acting cholinergic drug used to reverse the effects of certain medications used to prevent muscle contractions during surgical procedures. The brand name Enlon is discontinued, but generic versions may be available. Common side effects of Enlon (edrophonium injection) include watery eyes, vision problems, changes in your voice, nausea, vomiting, diarrhea, stomach pain, weakness, or muscle twitching.

The intravenous dosage of Enlon for adults: A tuberculin syringe containing 1 mL (10 mg) of Enlon is prepared with an intravenous needle, and 0.2 mL (2 mg) is injected intravenously within 15 to 30 seconds. The needle is left in situ. Only if no reaction occurs after 45 seconds is the remaining 0.8 mL (8 mg) injected. Enlon may interact with other drugs.
