About SYMLIN® (pramlintide acetate) injection

Taken at mealtime, SYMLIN is the first and only amylin mimetic for use in patients with diabetes treated with mealtime insulin. SYMLIN is a synthetic analog of human amylin, a naturally occurring hormone that is made in the beta cells of the pancreas, the same cells that make insulin. In patients with type 2 diabetes who use insulin, and in patients with type 1 diabetes, those cells in the pancreas are either damaged or destroyed, resulting in reduced secretion of both insulin and amylin after meals. The use of SYMLIN contributes to glucose control after meals.

The SymlinPen® (pramlintide acetate) pen-injector is an easy way for patients to use SYMLIN and offers convenient pre-filled SYMLIN administration with simple, dial-up dosing to improve mealtime glucose control. The SymlinPen®120 features fixed dosing to deliver 60 or 120 micrograms of SYMLIN per dose. The SymlinPen®60 features fixed dosing to deliver 15, 30, 45, or 60 micrograms of SYMLIN per dose.

Healthcare professionals and patients with diabetes may obtain more information, including the complete Prescribing Information and the Medication Guide, at www.SYMLIN.com.

Important Safety Information for SYMLIN

SYMLIN is not intended for all patients with diabetes. SYMLIN is used with insulin and has been associated with an increased risk of insulin-induced severe hypoglycemia, particularly in patients with type 1 diabetes. When severe hypoglycemia associated with SYMLIN use occurs, it is seen within three hours following a SYMLIN injection. If severe hypoglycemia occurs while operating a motor vehicle, heavy machinery, or while engaging in other high-risk activities, serious injuries may occur. Appropriate patient selection, careful patient instruction, and insulin dose adjustments are critical elements for reducing this risk.

Other adverse events commonly observed with SYMLIN when co-administered with insulin were mostly gastrointestinal in nature, including nausea, which was the most frequently reported adverse event. The incidence of nausea was higher at the beginning of SYMLIN treatment and decreased with time in most patients. The incidence and severity of nausea are reduced when SYMLIN is gradually increased to the recommended doses.

About BYETTA® (exenatide) injection

BYETTA is the first FDA-approved GLP-1 receptor agonist for the treatment of type 2 diabetes. BYETTA exhibits many of the same effects as the human incretin hormone glucagon-like peptide-1 (GLP-1). GLP-1 improves blood sugar after food intake through multiple effects that work in concert on the stomach, liver, pancreas and brain.

BYETTA is an injectable prescription medicine that may improve blood sugar (glucose) control in adults with type 2 diabetes mellitus, when used with a diet and exercise program. BYETTA is not insulin and should not be taken instead of insulin. BYETTA is not recommended to be taken with insulin. BYETTA is not for people with type 1 diabetes or people with diabetic ketoacidosis.

BYETTA provides sustained A1C control and low incidence of hypoglycemia when used alone or in combination with metformin or a thiazolidinedione, with potential weight loss. BYETTA is not a weight loss product. BYETTA was approved in April 2005 and has been used by more than one million patients since its introduction. See important safety information below.  Additional information about BYETTA is available at www.BYETTA.com.

Important Safety Information for BYETTA® (exenatide) injection

Based on post-marketing data, BYETTA has been associated with acute pancreatitis, including fatal and non-fatal hemorrhagic or necrotizing pancreatitis. The risk for getting low blood sugar is higher if BYETTA is taken with another medicine that can cause low blood sugar, such as a sulfonylurea. BYETTA should not be used in people who have severe kidney problems, and should be used with caution in people who have had a kidney transplant. Patients should talk with their healthcare provider if they have severe problems with their stomach, such as delayed emptying of the stomach (gastroparesis) or problems with digesting food. Severe allergic reactions can happen with BYETTA.

The most common side effects with BYETTA include nausea, vomiting, diarrhea, dizziness, headache, feeling jittery, and acid stomach. Nausea most commonly happens when first starting BYETTA, but may become less over time.

These are not all the side effects from use of BYETTA. A healthcare provider should be consulted about any side effect that is bothersome or does not go away.
