Exenatide injection may increase the risk that you will develop tumors of the thyroid gland, including medullary thyroid carcinoma (MTC; a type of thyroid cancer). Laboratory animals who were given exenatide developed tumors, but it is not known if this medication increases the risk of tumors in humans. Tell your doctor if you or anyone in your family has or has ever had MTC or Multiple Endocrine Neoplasia syndrome type 2 (MEN 2; condition that causes tumors in more than one gland in the body). If so, your doctor will probably tell you not to use exenatide injection. If you experience any of the following symptoms, call your doctor immediately: a lump or swelling in the neck; hoarseness; difficulty swallowing; or shortness of breath.
Keep all appointments with your doctor and the laboratory. Your doctor may order certain tests to check your body's response to exenatide.
Your doctor or pharmacist will give you the manufacturer's patient information sheet (Medication Guide) when you begin treatment with exenatide extended-release injection and each time you refill your prescription. Read the information carefully and ask your doctor or pharmacist if you have any questions. You can also visit the Food and Drug Administration (FDA) website (http://www.fda.gov/Drugs/DrugSafety/ucm085729.htm) or the manufacturer's website to obtain the Medication Guide.
Talk to your doctor about the risks of using exenatide injection.
WHY is this medicine prescribed?
Exenatide is used along with diet and exercise 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). Exenatide is in a class of medications called incretin mimetics. It works by stimulating the pancreas to secrete insulin when blood sugar levels are high. Insulin helps move sugar from the blood into other body tissues where it is used for energy. Exenatide also slows the emptying of the stomach and causes a decrease in appetite. Exenatide is not used to treat type 1 diabetes (condition in which the body does not produce insulin and therefore cannot control the amount of sugar in the blood). Exenatide is not used instead of insulin to treat people with diabetes who need 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. Using 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?
Exenatide immediate-release (Byetta® ) comes as a solution (liquid) in a prefilled dosing pen to inject subcutaneously (under the skin). Exenatide extended-release (long-acting) (Bydureon ® ) comes as a powder to be mixed with liquid in a vial or a prefilled dosing pen to inject subcutaneously. Exenatide immediate-release solution is usually injected twice a day within 60 minutes before the morning and evening meals; do not inject it after meals. Your doctor will probably start you on a low dose of exenatide immediate-release injection and may switch you to a pen with a higher dose of medication if your blood sugar control has not improved after you have used exenatide for 1 month. Exenatide extended-release solution is injected once weekly at any time of day without regard to meals. Use exenatide extended-release on the same day each week at any time of day. You may change the day of the week that you use exenatide extended-release if it has been 3 or more days since you used your last dose. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Use exenatide injection exactly as directed. Do not use more or less of it or use it more often than prescribed by your doctor.
If you are changing from exenatide immediate-release to exenatide extended-release, your glucose (sugar) levels may temporarily increase for 2 to 4 weeks after this change.
Exenatide controls diabetes but does not cure it. Continue to use exenatide even if you feel well. Do not stop using exenatide without talking to your doctor.
If you are using exenatide immediate-release (Byetta® ) prefilled dosing pens, you will need to buy needles separately. Ask your doctor or pharmacist what type of needles you will need to inject your medication. Be sure to read and understand the manufacturer's instructions for injecting exenatide using the pen. Also make sure you know how and when to set up a new pen. Ask your doctor or pharmacist to show you how to use the pen. Follow the directions carefully. Never remove the cartridge from the pen or attempt to add any other type of medication to the cartridge.
Always look at your exenatide solution before you inject it. It should be as clear, colorless, and fluid as water. Do not use exenatide if it is colored, cloudy, thickened, or contains solid particles, or if the expiration date on the bottle has passed. Do not mix exenatide with insulin into a single injection.
Never reuse needles and never share needles or pens. Always remove the needle right after you inject your dose. Dispose of needles in a puncture-resistant container. Ask your doctor or pharmacist how to dispose of the puncture resistant container.
Exenatide can be administered in the thigh (upper leg), abdomen (stomach), or upper arm. Use a different site for each injection, about 1 inch (2.5 centimeters) away from the previous injection but in the same general area (for example, the thigh). Use all available sites in the same general area before switching to a different area (for example, the upper arm). Do not use the same injection site more often than once every month.
You can inject extended release exentadine and insulin in the same general area of the body, but the injections should not be given right next to each other.

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. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA's Safe Disposal of Medicines website (http://goo.gl/c4Rm4p) for more information if you do not have access to a take-back program.
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
