Some Precautions and Warnings for Exenatide
Patients taking this drug should keep the following precautions and warnings in mind:
- Very preliminary data suggests incretin mimetics, such as exenatide, may increase the risk of precancerous cellular changes (called pancreatic duct metaplasia) in people with type 2 diabetes. Researchers are continuing to study the possibility that incretin mimetics might increase the risk of pancreatic cancer, although at this time there is not enough information to know for sure if there is any increased risk.
- Exenatide has been linked with some cases of pancreatitis (inflammation of the pancreas), a condition that is potentially life-threatening. Let your healthcare provider know if you develop any symptoms of pancreatitis, such as severe abdominal pain that radiates to the back and vomiting.
- Although exenatide is an injectable medication, it is not a form of insulin and should not be used to treat type 1 diabetes or diabetic ketoacidosis. These conditions need to be treated with insulin.
- Exenatide is a manmade version of a protein found in the saliva of gila monster lizards. As such, it may be more likely to cause allergic reactions. Talk to your healthcare provider if you develop an allergic reaction after taking exenatide. Also, in some people, the immune system may attack exenatide, perhaps making it less effective.
- Exenatide is not recommended for use in people with severe kidney disease, including kidney failure (renal failure). There have been reports of kidney problems related to this medication. Your healthcare provider should monitor your kidney function (using a simple blood test) while you are taking it.
- Exenatide has not been studied in people with diabetic gastroparesis or other digestive tract conditions. Exenatide is not recommended for use in people with severe digestive tract conditions, as it can slow the function of the digestive tract.
- When used by itself or in combination with medications such as metformin (Glucophage®), pioglitazone (Actos®), or rosiglitazone (Avandia®), exenatide does not increase the risk of low blood sugar by much. However, the risk of low blood sugar is significantly higher when exenatide is used with the following sulfonylurea medications:
Your healthcare provider may need to lower your dose of any of the above medications if you are taking exenatide (see Byetta and Blood Sugar).
- Exenatide is considered a pregnancy Category C medication. This means that it may not be safe for use in pregnant women, although the full risks of exenatide in pregnancy are not known. Talk to your healthcare provider before taking exenatide during pregnancy (see Byetta and Pregnancy).
- It is not known if exenatide passes through breast milk. Therefore, if you are breastfeeding or plan to start breastfeeding, be sure to talk with your healthcare provider about breastfeeding while taking exenatide.
