What is Dextrose?
Dextrose is a simple sugar made from starch. Starch is a naturally occurring complex carbohydrate found in many plants, including corn, wheat, rice, and potato. The most common source of dextrose is corn starch.
Dextrose, when used as a medication, is given either by mouth (orally) or by injection. Dextrose is also known as D-glucose.
Dextrose is used to treat very low blood sugar (hypoglycemia), most often in people with diabetes mellitus. Dextrose is given by injection to treat insulin shock (low blood sugar caused by using insulin and then not eating a meal or eating enough food afterward). Dextrose works by quickly increasing the amount of glucose in your blood. Glucose is found in foods rich in carbohydrates, such as bread, cereal, potatoes, fruit, pasta, and rice. Glucose is a source of energy, and all the cells and organs in your body need glucose to function properly.
Dextrose is also used to provide carbohydrate calories to a person who cannot eat because of illness, trauma, or other medical condition. It is sometimes given to people who are sick from drinking too much alcohol.
Dextrose may also be used to treat hyperkalemia (high levels of potassium in your blood).
