What is Dextrose (glucose oral/injection)?
Glucose is a form of natural sugar that is normally produced by the liver. Glucose is a source of energy, and all the cells and organs in your body need glucose to function properly. Glucose as a medication is given either by mouth (orally) or by injection.
Glucose is used to treat very low blood sugar (hypoglycemia), most often in people with diabetes mellitus. Glucose 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). This medicine works by quickly increasing the amount of glucose in your blood.
Glucose is also used to provide carbohydrate calories to a person who cannot eat because of illness, trauma, or other medical condition. Glucose is sometimes given to people who are sick from drinking too much alcohol.
Glucose may also be used to treat hyperkalemia (high levels of potassium in your blood).
Glucose may also be used for purposes not listed in this medication guide.

How should I use Dextrose (glucose oral/injection)?
Follow all directions on your prescription label. Do not use this medicine in larger or smaller amounts or for longer than recommended.
The chewable tablet must be chewed before you swallow it.
If you take glucose gel in a pre-measured tube, be sure to swallow the entire contents of the tube to get a full dose.
Your hypoglycemia symptoms should improve in about 10 minutes after taking oral glucose. If not, take another dose. Seek medical attention if you still have hypoglycemia symptoms after taking two doses.
Glucose injection is given through an IV into a vein. Do not inject this medicine into a muscle or under the skin. A glucose injection should be given only as an intravenous (IV) injection.
A glucose injection should be given slowly. Tell your caregivers if you feel any burning, pain, or swelling around the IV needle when glucose is injected.
You may be shown how to use an IV at home. Do not give yourself this medicine if you do not understand how to use the injection and properly dispose of needles, IV tubing, and other items used.
Use a disposable needle, syringe, or prefilled syringe only once. Follow any state or local laws about throwing away used needles and syringes. Use a puncture-proof "sharps" disposal container (ask your pharmacist where to get one and how to throw it away). Keep this container out of the reach of children and pets.
Call your doctor if your symptoms do not improve, or if they get worse.
Check the expiration date on your medicine label each time you use glucose. If the medicine has been stored for a long time, the expiration date may have passed and the glucose may not work as well.
Store at room temperature away from moisture and heat. Keep the medicine container tightly closed when not in use.
