What is Byetta Prefilled Pen?
This medication guide provides information about the Byetta brand of exenatide. Bydureon is another brand of exenatide that is not covered in this medication guide.
Exenatide is an injectable diabetes medicine that helps control blood sugar levels. This medication helps your pancreas produce insulin more efficiently. Byetta is a short-acting form of exenatide.
Byetta is used together with diet and exercise to improve blood sugar control in adults with type 2 diabetes. Byetta is not for treating type 1 diabetes.
Byetta may also be used for purposes not listed in this medication guide.
Warnings
You should not use this medicine if you are allergic to exenatide (Bydureon or Byetta), or if you have:
- severe kidney disease (or if you are on dialysis);
- a severe stomach disorder that causes slow digestion;
- a history of low levels of platelets (blood cells that help your blood to clot) while using exenatide; or
- diabetic ketoacidosis (call your doctor for treatment with insulin).
Tell your doctor if you have ever had:
- kidney disease or a history of kidney transplant;
- a stomach disorder that causes slow digestion;
- pancreatitis; or
- gall stones.
Follow your doctor's instructions about using this medicine if you are pregnant or you become pregnant. Controlling diabetes is very important during pregnancy, and having high blood sugar may cause complications in both the mother and the baby.
Byetta can make birth control pills less effective. If you take birth control pills, take your pill at least 1 hour before your Byetta injection.
It may not be safe to breastfeed while using this medicine. Ask your doctor about any risk.
Exenatide is not approved for use by anyone younger than 18 years old.
How should I use Byetta Prefilled Pen
Use Byetta Prefilled Pen (Subcutaneous) exactly as directed on the label, or as prescribed by your doctor. Do not use in larger or smaller amounts or for longer than recommended.
Follow all directions on your prescription label and read all medication guides or instruction sheets. Your doctor may occasionally change your dose. Use the medicine exactly as directed.
Byetta is injected under the skin. A healthcare provider may teach you how to properly use the medication by yourself.
Read and carefully follow any Instructions for Use provided with your medicine. Ask your doctor or pharmacist if you don't understand all instructions.
Prepare your injection only when you are ready to give it. You must give the injection right away after mixing.
Byetta is usually injected twice a day, before the morning and evening meals. Do not use after eating a meal. You must use Byetta within 60 minutes (1 hour) before eating. Your Byetta doses should be given at least 6 hours apart.
You may have low blood sugar (hypoglycemia) and feel very hungry, dizzy, irritable, confused, anxious, or shaky. To quickly treat hypoglycemia, eat or drink a fast-acting source of sugar (fruit juice, hard candy, crackers, raisins, or non-diet soda).
Your doctor may prescribe a glucagon injection kit in case you have severe hypoglycemia. Be sure your family or close friends know how to give you this injection in an emergency.
Also watch for signs of high blood sugar (hyperglycemia) such as increased thirst or urination.
Blood sugar levels can be affected by stress, illness, surgery, exercise, alcohol use, or skipping meals. Ask your doctor before changing your dose or medication schedule.
Use a needle and syringe only once and then place them in a puncture-proof "sharps" container. Follow state or local laws about how to dispose of this container. Keep it out of the reach of children and pets.
Never share an injection pen or syringe with another person, even if the needle has been changed. Sharing these devices can allow infections or disease to pass from one person to another.
Byetta can lower your platelet counts for up to 10 weeks after you stop using this medicine. You may need frequent medical tests while using this medicine and for a short time after you stop.
Byetta is only part of a complete treatment program that may also include diet, exercise, weight control, regular blood sugar testing, and special medical care. Follow your doctor's instructions very closely.
