Dex4 is used to treat very low blood sugar (hypoglycemia), most often in people with diabetes mellitus. Dex4 works by quickly increasing the amount of glucose in your blood.

Dex4 is also used to provide carbohydrate calories to a person who cannot eat because of illness, trauma, or other medical condition. This medicine is sometimes given to people who are sick from drinking too much alcohol.

Dex4 may also be used to treat hyperkalemia (high levels of potassium in your blood).

Dex4 may also be used for purposes not listed in this medication guide.

Follow all directions on your medicine label and package. Tell each of your healthcare providers about all your medical conditions, allergies, and all medicines you use.

Use exactly as directed on the label, or as prescribed by your doctor.

You must chew the chewable tablet before you swallow it.

Measure liquid medicine carefully. Use the dosing syringe provided, or use a medicine dose-measuring device (not a kitchen spoon).

If you take Dex4 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 Dex4. If not, take another dose.

Seek medical attention if you still have hypoglycemia symptoms after taking two doses.
