Important safety information:
- Nateglinide may cause dizziness. This effect may be worse if you take it with alcohol or certain medicines. Use nateglinide with caution. Do not drive or perform other possibly unsafe tasks until you know how you react to it.

- Strenuous exercise, drinking alcohol, fever, infection, surgery, trauma, dieting, and skipping meals can affect your blood sugar levels.

- Check your blood sugar levels as directed by your doctor. If they are often higher or lower than they should be and you take nateglinide exactly as prescribed, tell your doctor.

It may also make your heart beat faster; make your vision change; give you a headache, chills, or tremors; or make you more hungry. It is a good idea to carry a reliable source of glucose (eg, tablets or gel) to treat low blood sugar. If this is not available, you should eat or drink a quick source of sugar like table sugar, honey, candy, orange juice, or non-diet soda. This will raise your blood sugar level quickly. Tell your doctor right away if this happens. To prevent low blood sugar, eat meals at the same time each day and do not skip meals.
- Tell your doctor or dentist that you take nateglinide before you receive any medical or dental care, emergency care, or surgery.
