  • Carry an ID card at all times that says you have diabetes. Check your blood sugar levels as directed by your doctor. If they are often higher than they should be and you take Byetta exactly as prescribed, tell your doctor.
  • Follow the diet and exercise program given to you by your health care provider. Proper diet, regular exercise, and regular testing of blood sugar are important for best results when using Byetta .
  • The risk of low blood sugar may be increased when Byetta is used with certain other diabetes medicines (eg, sulfonylureas, thiazolidinediones). Low blood sugar may make you anxious, sweaty, weak, dizzy, drowsy, or faint.

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.

  • If vomiting or diarrhea occurs, you will need to take care not to become dehydrated. Contact your doctor for instructions.
  • Do not store the pen with the needle attached. If the needle is left on, the medicine may leak from the pen or air bubbles may form in the cartridge.
  • Lab tests, including hemoglobin A1c levels and blood sugar levels, may be performed while you use Byetta . These tests may be used to monitor your condition or check for side effects. Be sure to keep all doctor and lab appointments.
  • Byetta should be used with extreme caution in CHILDREN; safety and effectiveness in children have not been confirmed.
