Information on Tablets A-Z
Nateglinide is used alone or in combination with other medications to treat type 2 (noninsulin-dependent) diabetes (formerly called 'adult-onset') in people whose diabetes cannot be controlled by diet and exercise alone. Nateglinide belongs to a class of drugs called meglitinides. Nateglinide helps your body regulate the amount of glucose (sugar) in your blood. It decreases the amount of glucose by stimulating the pancreas to release insulin.
How should this medicine be used:
Nateglinide comes as a tablet to take by mouth. It is usually taken three times daily. Take nateglinide any time from 30 minutes before a meal to just before the meal. If you skip a meal, you need to skip the dose of nateglinide. If you add a meal, add a dose of nateglinide. Your doctor may gradually increase your dose, depending on your response to nateglinide. Monitor your blood glucose closely. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take nateglinide exactly as directed. Do not take more or less of it or take it more often than directed by the package label or prescribed by your doctor.
Nateglinide controls diabetes but does not cure it. Continue to take nateglinide even if you feel well. Do not stop taking nateglinide without talking with your doctor.
Other uses for this medicine:
This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.

Special dietary instructions:
Be sure to follow all exercise and dietary recommendations made by your doctor or dietitian. Calorie reduction, weight loss, and exercise will help control your diabetes and will also make nateglinide work better. It is important to eat a healthful diet. Alcohol increases blood sugar; ask your doctor for information on how much is safe to drink.
If I forget a dose:
Before you start taking nateglinide, ask your doctor what to do if you forget to take a dose. Write these directions down so you can refer to them later. As a general rule, if you have just begun to eat a meal, take the missed dose as soon as you remember it. However, if you have finished eating, or if it is almost time for the next dose, skip the missed dose and continue your regular dosing schedule. Do not take a double dose to make up for a missed one.

You should know the symptoms of low and high blood sugar and what to do if you have them.
If you have any of the symptoms of low blood sugar (hypoglycemia), eat or drink a food or beverage with sugar in it, such as hard candy or fruit juice, and call your doctor immediately. The symptoms of low blood sugar include:
