What is Dex4?

Dex4 is used to treat very low blood sugar (hypoglycemia), mainly in people with diabetes mellitus. Dex4 quickly raises the amount of glucose in your blood.

Dex4 is also used to give carbohydrate calories to someone who cannot eat due to illness, trauma, or other medical conditions. This medicine is sometimes given to people who feel 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 mentioned in this medication guide.

How should I take Dex4?

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

You must chew the chewable tablet before swallowing it.

Measure liquid medicine carefully. Use the dosing syringe provided, or 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.

Call your doctor if your symptoms do not improve, or if they get worse.

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

Store at room temperature away from moisture and heat. Do not refrigerate or freeze. Keep the medicine container tightly closed when not in use.
