With the updated label, refrigeration of BYETTA is no longer required after first use. Patients can now keep a BYETTA Pen at a temperature anywhere from 36 degrees F (2 degrees C) to 77 degrees F (25 degrees C) after first use. Until first use, BYETTA Pens must continue to be stored in a refrigerator between 36 degrees F (2 degrees C) and 46 degrees F (8 degrees C). These new, more convenient storage instructions will be provided to patients and healthcare professionals during the next few weeks. Patients now using BYETTA can immediately begin storing their current, in use BYETTA Pen at a room temperature not to exceed 77 degrees F (25 degrees C). BYETTA Pens should be protected from light and never frozen.

This change further enhances the convenience of BYETTA for patients. BYETTA is available in a simple-to-use 5 microgram and 10 microgram fixed dose pen device. Unlike insulin, the dose of BYETTA does not need to be adjusted based on the size of meals or amount of exercise, and no additional blood glucose monitoring is required.

“My patients already find BYETTA simple and easy to use,” said Deborah Hinnen, RN, ARNP, CDE, BC-ADM, FAAN, Diabetes Nurse Specialist and Coordinator of Diabetes Education Services, Mid America Diabetes Associates, Wichita, Kansas. “The ability to store the BYETTA Pen without the need for refrigeration after first use is an improved convenience that makes it even easier for people with type 2 diabetes to take advantage of the unique clinical benefits of BYETTA.”

Patients on BYETTA therapy at 2.5 years showed sustained A1C control with a secondary benefit of weight loss. BYETTA improved blood sugar control by lowering both post-meal and fasting (early morning) glucose levels, resulting in better long-term control as measured by A1C. BYETTA helps control blood sugar through five unique actions in one therapy, including the stimulation of insulin secretion only when blood sugar is high. BYETTA restores the first-phase insulin response (an activity of the cells in the pancreas that is lost in patients who have type 2 diabetes), decreases glucose output from the liver, regulates gastric emptying, and decreases food intake.

About BYETTA

BYETTA is the first in a new class of drugs for the treatment of type 2 diabetes called incretin mimetics. BYETTA exhibits many of the same effects as the human incretin hormone glucagonlike peptide-1 (GLP-1). GLP-1 improves blood sugar after food intake through multiple effects that work in concert on the intestine, liver, pancreas and brain.1 BYETTA is approved by the FDA for use by people with type 2 diabetes who are unsuccessful at controlling their blood sugar levels despite using the commonly prescribed oral medications metformin, a sulfonylurea, or a thiazolidinedione.

About Diabetes

Diabetes affects more than 20 million in the United States and an estimated 194 million adults worldwide.2, 3 Approximately 90-95 percent of those affected have type 2 diabetes. People who have type 2 diabetes either do not produce enough insulin and/or the cells in the body do not respond normally to insulin. Diabetes is the fifth leading cause of death by disease in the United States and costs approximately $132 billion per year in direct and indirect medical expenses.4 Type 2 diabetes usually occurs in adults over the age of 40, but is increasingly common in younger people.

According to the Centers for Disease Control and Prevention’s National Health and Nutrition Examination Survey, approximately 60 percent of people with diabetes do not achieve target A1C levels (the target is less than 7.0%, according to American Diabetes Association guidelines) with their current treatment regimen.5

Important Safety Information for BYETTA® (exenatide) injection

BYETTA improves glucose (blood sugar) control in patients with type 2 diabetes who are taking metformin, a sulfonylurea, or a thiazolidinedione. BYETTA is not a substitute for insulin in patients whose diabetes requires insulin treatment. BYETTA is not recommended for use in patients with severe problems with the stomach or food digestion, or those who have severe kidney disease. Before using BYETTA, patients should tell their healthcare provider if they are pregnant, plan to become pregnant, or are breastfeeding. BYETTA has not been studied in children.

When BYETTA is used with a medicine that contains a sulfonylurea, hypoglycemia (low blood sugar) is a possible side effect. To reduce this possibility, the dose of sulfonylurea medicine may need to be reduced while using BYETTA. Other common side effects with BYETTA include nausea, vomiting, diarrhea, dizziness, headache, feeling jittery, and acid stomach. Nausea is most common when first starting BYETTA, but decreases over time in most patients. BYETTA may reduce appetite, the amount of food eaten, and body weight. No changes in dose are needed for these side effects. These are not all the side effects with BYETTA. A healthcare provider should be consulted about any side effect that is bothersome or does not go away.
