Maybe your doctor has told you about a shot called EDTA. Or maybe someone close to you has been prescribed this treatment. Hearing this name can make you feel a little scared. But what exactly is this EDTA shot? What are the possible side effects? Let's talk about all this simply, in a way that you can understand.
What kind of medicine is EDTA?
Simply put, Edetate Disodium (EDTA) is a special medication that binds to excess calcium and other heavy metals in our bodies and helps remove them from the body. It works like a magnet, pulling unwanted substances and removing them.
This is mainly used in two special cases:
1. When the calcium level in the blood increases dangerously (Calcium Overload): If the calcium level in the body becomes uncontrollably high due to certain medical conditions, this medicine is used to remove the excess calcium and bring it back to normal levels.
2. Digitalis-induced heart rhythm disorders: Digoxin is a drug used to treat heart disease. When this drug becomes too high in the body, the heart can become irregular. In such cases, EDTA is used to restore the heart rate.
The most important things to tell your doctor before starting treatment
Before deciding if this treatment is right for you, your doctor will need to know your complete health history. Therefore, be sure to tell your doctor if you have any of the following conditions:
- If you have diabetes .
- If you have heart disease or heart failure .

- If you have previously had an allergic reaction to EDTA medication or any other medication, food, or dye .
