Interactions
7 DRUG INTERACTIONS Table 6: Clinically Relevant Interactions with Exenatide Concomitant Use of Insulin Secretagogues or Insulin Clinical Impact Exenatide promotes insulin release from pancreatic beta-cells in the presence of elevated glucose concentrations. The risk of hypoglycemia is increased when exenatide is used in combination with insulin secretagogues (e.g., sulfonylureas) or insulin [see Warnings and Precautions (5.3) and Adverse Reactions (6) ] . Intervention When initiating exenatide, consider reducing the dose of concomitantly administered insulin secretagogue or insulin to reduce the risk of hypoglycemia. Warfarin Clinical Impact In a drug interaction study, exenatide did not have a significant effect on INR [see Clinical Pharmacology (12.3) ] .
Warnings
5 WARNINGS AND PRECAUTIONS Acute Pancreatitis : Has been observed in patients treated with GLP-1 receptor agonists, including exenatide. Discontinue if pancreatitis is suspected. ( 5.1 ) Never share an exenatide injection pen between patients, even if the needle is changed. ( 5.2 ) Hypoglycemia with Concomitant Use of Insulin Secretagogues or Insulin : Patients taking an insulin secretagogue or insulin may have an increased risk of hypoglycemia, including severe hypoglycemia. Reduction in the dose of insulin secretagogues or insulin may be necessary. ( 5.3 ) Acute Kidney Injury Due to Volume Depletion : Monitor renal function in patients reporting adverse reactions that could lead to volume depletion. 4 CONTRAINDICATIONS Exenatide injection is contraindicated in patients with: A prior severe hypersensitivity reaction to exenatide or to any of the excipients in exenatide injection. Serious hypersensitivity reactions including anaphylaxis and angioedema have been reported with exenatide injection [see Warnings and Precautions (5.7) ] .
Pregnancy
8.1 Pregnancy Risk Summary Limited data with exenatide in pregnant women are not sufficient to determine a drug-associated risk for major birth defects or miscarriage. There are risks to the mother and fetus associated with poorly controlled diabetes in pregnancy (see Clinical Considerations) . Based on animal reproduction studies, there may be risks to the fetus from exposure to exenatide during pregnancy. Exenatide should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.
