Nateglinide
Brand Name(s): Starlix®; also available generically
WHY is this medicine prescribed?
Nateglinide is used alone or in combination with other medications to treat type 2 diabetes (condition in which the body does not use insulin normally and therefore cannot control the amount of sugar in the blood) 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.
Over time, people who have diabetes and high blood sugar can develop serious or life-threatening complications, including heart disease, stroke, kidney problems, nerve damage, and eye problems. Taking medication(s), making lifestyle changes (e.g., diet, exercise, quitting smoking), and regularly checking your blood sugar may help to manage your diabetes and improve your health. This therapy may also decrease your chances of having a heart attack, stroke, or other diabetes-related complications such as kidney failure, nerve damage (numb, cold legs or feet; decreased sexual ability in men and women), eye problems, including changes or loss of vision, or gum disease. Your doctor and other healthcare providers will talk to you about the best way to manage your diabetes.
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.

What should I know about STORAGE and DISPOSAL of this medication?
Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom).
It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. http://www.upandaway.org
Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet.
