Proglycem raises blood sugar by slowing the release of insulin from the pancreas.

Proglycem is used to treat low blood sugar (hypoglycemia) caused by certain cancers or other conditions that can make the pancreas release too much insulin. Proglycem is for use in adults and children as young as infants.

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

You should not take Proglycem to treat occasional low blood sugar caused by diet.

Follow all directions on your prescription label. Your doctor may occasionally change your dose to make sure you get the best results. Do not take Proglycem in larger or smaller amounts or for longer than recommended.

Shake the oral suspension (liquid) well just before you measure a dose. Measure liquid medicine with the dosing syringe provided, or with a special dose-measuring spoon or medicine cup. If you do not have a dose-measuring device, ask your pharmacist for one.

Proglycem is usually taken every 8 to 12 hours. Take the medicine at the same time intervals each day.

Proglycem usually begins to work within 1 hour, and its effects can last up to 8 hours.

Your blood sugar will need to be checked often, and your urine may also need to be tested for ketones. Call your doctor at once if you have abnormal test results. You may need other blood tests at your doctor's office.

Proglycem is only part of a treatment program that may also include diet. Follow your doctor's instructions very closely.
