Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.
Liver disease: If you have moderate-to-severe liver disease, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Low blood glucose: This medication may cause low blood glucose (hypoglycemia). Certain people are more sensitive to this effect, including seniors, people who are undernourished, and people who have exercised more strenuously than usual. If you are taking other diabetes medications, have consumed alcohol, or have other medical conditions that cause low blood glucose (e.g., an underactive pituitary or adrenal gland, or kidney problems), you may need to check your blood glucose levels more frequently. Consult your doctor for advice about whether any special monitoring is necessary.
Pregnancy: This medication should not be used during pregnancy. If you think you may be pregnant or if you become pregnant while taking this medication, contact your doctor immediately.
Breast-feeding: It is not known if nateglinide passes into breast milk. If you are a breast-feeding mother and are taking this medication, it may affect your baby. Talk to your doctor about whether you should continue breast-feeding.
Children: The safety and effectiveness of using this medication have not been established for children.
