Xultophy^® 100/3.6 (insulin degludec and liraglutide) injection 100 units/mL and 3.6 mg/mL is a combination of insulin degludec and liraglutide and is indicated as an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes mellitus.

• Xultophy^® 100/3.6 is not recommended as first-line therapy for patients who have inadequate glycemic control on diet and exercise.
• Xultophy^® 100/3.6 is not recommended for use in combination with any other product containing liraglutide or another GLP-1 receptor agonist (GLP-1 RA).
• Xultophy^® 100/3.6 is not indicated for use in patients with type 1 diabetes mellitus or for the treatment of diabetic ketoacidosis.
• Xultophy^® 100/3.6 has not been studied in combination with prandial insulin.

• Xultophy^® 100/3.6 is contraindicated in patients with a personal or family history of medullary thyroid carcinoma (MTC) or in patients with Multiple Endocrine Neoplasia syndrome type 2 (MEN 2), during episodes of hypoglycemia, and in patients with hypersensitivity to Xultophy^® 100/3.6, either of the active substances, or any of its excipients. Serious hypersensitivity reactions including anaphylactic reactions and angioedema have been reported with liraglutide, one of the components of Xultophy^® 100/3.6.

• Risk of Thyroid C-cell Tumors: If serum calcitonin is measured and found to be elevated or thyroid nodules are noted on physical examination or neck imaging, the patient should be further evaluated.
• Pancreatitis: Acute pancreatitis, including fatal and non-fatal hemorrhagic or necrotizing pancreatitis, has been observed in patients treated with liraglutide postmarketing. Observe patients carefully for signs and symptoms of pancreatitis (persistent severe abdominal pain, sometimes radiating to the back with or without vomiting). If pancreatitis is suspected, discontinue Xultophy^® 100/3.6 promptly and if pancreatitis is confirmed, do not restart. Liraglutide, one of the components of Xultophy^® 100/3.6, has been studied in a limited number of patients with a history of pancreatitis. It is unknown if patients with a history of pancreatitis are at a higher risk for development of pancreatitis on liraglutide.
• Never Share a Xultophy^® 100/3.6 Pen Between Patients, even if the needle is changed. Sharing of the pen poses a risk for transmission of blood-borne pathogens.
• Hyperglycemia or Hypoglycemia with Changes in Insulin Regimen: Changes in an insulin regimen (e.g., insulin strength, manufacturer, type, or injection site or method of administration) may affect glycemic control and predispose to hypoglycemia or hyperglycemia. Repeated insulin injections into areas of lipodystrophy or localized cutaneous amyloidosis have been reported to result in hyperglycemia; and a sudden change in the injection site (to an unaffected area) has been reported to result in hypoglycemia. Make any changes to a patient’s insulin regimen under close medical supervision with increased frequency of blood glucose monitoring. Advise patients who have repeatedly injected into areas of lipodystrophy or localized cutaneous amyloidosis to change the injection site to unaffected areas and closely monitor for hypoglycemia. Adjustments in concomitant anti-diabetic treatment may be needed.
• Overdose Due to Medication Errors: Instruct patients to check the label before each injection since accidental mix-ups with insulin containing products can occur. Do not administer more than 50 units of Xultophy^® 100/3.6 daily. Do not exceed the 1.8 mg maximum recommended dose of liraglutide or use with other GLP-1 RAs.
• Hypoglycemia: Hypoglycemia is the most common adverse reaction of insulin-containing products, including Xultophy^® 100/3.6. Severe hypoglycemia can cause seizures, may be life threatening or cause death. Hypoglycemia can impair concentration ability and reaction time which may place the patient and others at risk in situations where these abilities are important. Hypoglycemia can happen suddenly and symptoms may differ in each patient and change over time in the same patient. Symptomatic awareness of hypoglycemia may be less pronounced in patients with longstanding diabetes, diabetic neuropathy, and in patients using drugs that block the sympathetic nervous system, or who experience recurrent hypoglycemia. The long-acting effect of insulin degludec may delay recovery from hypoglycemia compared to shorter acting insulins. Increase monitoring with changes to: dose, co-administered glucose lowering medications, concomitant drugs, meal pattern, physical activity; and in patients with hypoglycemia unawareness or renal or hepatic impairment.
• Acute Kidney Injury: Acute renal failure and worsening of chronic renal failure, which may sometimes require hemodialysis, have been reported postmarketing for liraglutide, usually in association with nausea, vomiting, diarrhea, or dehydration. Advise patients of the potential risk of dehydration due to gastrointestinal adverse reactions and take precautions to avoid fluid depletion.
• Hypersensitivity and Allergic Reactions: Severe, life-threatening, generalized allergy, including anaphylaxis, angioedema, bronchospasm, hypotension, and shock can occur with insulins, including Xultophy^® 100/3.6. There have been postmarketing reports of serious hypersensitivity reactions (e.g. anaphylactic reactions and angioedema) in patients treated with liraglutide, one of the components of Xultophy^® 100/3.6. If a hypersensitivity reaction occurs, discontinue and treat promptly per standard of care, and monitor until signs and symptoms resolve. Anaphylaxis and angioedema have been reported with other GLP-1 RAs. Use caution in a patient with a history of anaphylaxis or angioedema with other GLP-1 RAs because it is unknown whether such patients will be predisposed to these reactions with Xultophy^® 100/3.6.
• Acute Gallbladder Disease: Acute events of gallbladder disease such as cholelithiasis or cholecystitis have been reported in GLP-1 receptor agonist trials and postmarketing. In a cardiovascular outcomes trial (LEADER trial) 3.1% of patients treated with liraglutide, one of the components of Xultophy^® 100/3.6, versus 1.9% of placebo treated patients reported an acute event of gallbladder disease, such as cholelithiasis or cholecystitis. If cholelithiasis is suspected, gallbladder studies and appropriate clinical follow-up are indicated.
• Hypokalemia: All insulin containing products, including Xultophy^® 100/3.6 can lead to life-threatening hypokalemia, which may then cause respiratory paralysis, ventricular arrhythmia, and death. Monitor potassium levels in patients at risk for hypokalemia and treat if indicated.
• Fluid Retention and Congestive Heart Failure: Patients using insulin containing products, including Xultophy^® 100/3.6, with thiazolidinediones (TZDs) should be observed for signs and symptoms of heart failure. If heart failure develops, dosage reduction or discontinuation of the TZD must be considered.

• The most common adverse reactions, reported in ≥5% of patients treated with Xultophy^® 100/3.6 are nasopharyngitis, headache, nausea, diarrhea, increased lipase and upper respiratory tract infection.

• Certain drugs may affect glucose metabolism, requiring dose adjustment and close monitoring of blood glucose. The signs and symptoms of hypoglycemia may be reduced or absent in patients taking anti-adrenergic drugs (e.g., beta-blockers, clonidine, guanethidine, and reserpine).
• Liraglutide-containing products, including Xultophy^® 100/3.6, cause a delay of gastric emptying, and thereby have the potential to impact the absorption of concomitantly administered oral medications. Caution should be exercised when oral medications are concomitantly administered with liraglutide-containing products.
