What is Prandin?

Prandin (repaglinide) 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.

Important Information

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.

Before taking this medicine

You should not use Prandin if you are allergic to repaglinide, or if you have:

  • severe liver disease; or

  • diabetic ketoacidosis (call your doctor for treatment).

Many drugs can interact with repaglinide and some drugs should not be used at the same time. Your doctor may change your treatment plan if you also use:

To make sure Prandin is safe for you, tell your doctor if you have ever had:

  • liver disease; or

  • if you also take metformin or other diabetes medicines.

Follow your doctor's instructions about using Prandin if you are pregnant or you become pregnant. Controlling diabetes is very important during pregnancy, and having high blood sugar may cause complications in both the mother and the baby.

You should not breastfeed while using repaglinide.

Prandin is not approved for use by anyone younger than 18 years old.

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.

What other drugs will affect Prandin?

Many other medicines that can increase or decrease the effects of repaglinide on lowering your blood sugar. Some drugs can also cause you to have fewer symptoms of hypoglycemia, making it harder to tell when your blood sugar is low.
