With the rapid introduction of the drug physiological mechanisms do not have time to eliminate a decrease in serum calcium levels and may develop acute tetany.

EDTA, due to the ability to bind calcium ions, is also used as an anticoagulant in the preservation of blood.

With the introduction of the drug into a vein, and sometimes there is a burning sensation that can spread throughout the body and persist for 1 - 2 hours after the end of infusion.
