What is Prandin?

Prandin is an oral diabetes medicine that helps control blood sugar levels by causing the pancreas to produce insulin.

Prandin is used together with diet and exercise to improve blood sugar control in adults with type 2 diabetes mellitus.

Prandin is not for treating type 1 diabetes.

Warnings

You should not use Prandin if you have type 1 diabetes, severe liver disease, or diabetic ketoacidosis.

You should not use Prandin together with gemfibrozil or NPH insulin (such as isophane insulin).

Prandin is only part of a complete program of treatment that also includes diet, exercise, and weight control. Follow your diet, medication, and exercise routines very closely. Changing any of these factors can affect your blood sugar levels.

How should I take Prandin?

Take Prandin exactly as prescribed by your doctor. Follow all directions on your prescription label and read all medication guides or instruction sheets. Your doctor may occasionally change your dose.

Prandin is usually taken 2 to 4 times daily, within 30 minutes before eating a meal. Follow your doctor's instructions. If you skip a meal, do not take your dose of Prandin. Wait until your next meal.

Your blood sugar will need to be checked often, and you may need other blood tests at your doctor's office.

You may have low blood sugar (hypoglycemia) and feel very hungry, dizzy, irritable, confused, anxious, or shaky. To quickly treat hypoglycemia, eat or drink a fast-acting source of sugar (fruit juice, hard candy, crackers, raisins, or non-diet soda).

Your doctor may prescribe a glucagon injection kit in case you have severe hypoglycemia. Be sure your family or close friends know how to give you this injection in an emergency.

Also watch for signs of high blood sugar (hyperglycemia) such as increased thirst or urination.

Blood sugar levels can be affected by stress, illness, surgery, exercise, alcohol use, or skipping meals. Ask your doctor before changing your dose or medication schedule.

Prandin is only part of a treatment program that may also include diet, exercise, weight control, blood sugar testing, and special medical care. Follow your doctor's instructions very closely.

Store at room temperature away from moisture and heat.
