Liraglutide: What to Know Before You Take It

5 WARNINGS AND PRECAUTIONS Acute Pancreatitis : Has been observed in patients treated with GLP-1 receptor agonists, including liraglutide injection. Discontinue if pancreatitis is suspected. ( 5.2 ) Never Share a liraglutide injection Pen Between Patients, even if the needle is changed. ( 5.3 ) Hypoglycemia : Adult patients taking an insulin secretagogue or insulin may have an increased risk of hypoglycemia, including severe hypoglycemia. In pediatric patients 10 years of age and older, the risk of hypoglycemia was higher with liraglutide injection regardless of insulin and/or metformin use. Reduction in the dose of insulin secretagogues or insulin may be necessary. ( 5.4 ) A cute Kidney Injury Due to Volume Depletion : Monitor renal function in patients reporting adverse reactions that could lead to volume depletion. ( 5.5 ) S evere Gastrointestinal Adverse Reactions : Use has been associated with gastrointestinal adverse reactions, sometimes severe. Liraglutide injection is not recommended in patients with severe gastroparesis. ( 5.6 ) Hypersensitivity Reactions : Postmarketing reports of serious hypersensitivity reactions (e.g., anaphylactic reactions and angioedema). Discontinue liraglutide injection and promptly seek medical advice. ( 5.7 ) Acute Gallbladder Disease : If cholelithiasis or cholecystitis are suspected, gallbladder studies are indicated. ( 5.8 ) Pulmonary Aspiration During General Anesthesia or Deep Sedation : Has been reported in patients receiving GLP-1 receptor agonists undergoing elective surgeries or procedures. Instruct patients to inform healthcare providers of any planned surgeries or procedures. ( 5.9 ) 5.1 Risk of Thyroid C-cell Tumors Liraglutide causes dose-dependent and treatment-duration-dependent thyroid C-cell tumors (adenomas and/or carcinomas) at clinically relevant exposures in both genders of rats and mice [see Nonclinical Toxicology ( 13.1 )] . Malignant thyroid C-cell carcinomas were detected in rats and mice. It is unknown whether liraglutide injection will cause thyroid C-cell tumors, including medullary thyroid carcinoma (MTC), in humans, as the human relevance of liraglutide-induced rodent thyroid C-cell tumors has not been determined. Cases of MTC in patients treated with liraglutide injection have been reported in the postmarketing period; the data in these reports are insufficient to establish or exclude a causal relationship between MTC and liraglutide injection use in humans. Liraglutide injection is contraindicated in patients with a personal or family history of MTC or in patients with MEN 2. Counsel patients regarding the potential risk for MTC with the use of liraglutide injection and inform them of symptoms of thyroid tumors (e.g., a mass in the neck, dysphagia, dyspnea, persistent hoarseness). Routine monitoring of serum calcitonin or using thyroid ultrasound is of uncertain value for early detection of MTC in patients treated with liraglutide injection. Such monitoring may increase the risk of unnecessary procedures, due to low test specificity for serum calcitonin and a high background incidence of thyroid disease. Significantly elevated serum calcitonin may indicate MTC and patients with MTC usually have calcitonin values >50 ng/L. If serum calcitonin is measured and found to be elevated, the patient should be further evaluated. Patients with thyroid nodules noted on physical examination or neck imaging should also be further evaluated. 5.2 Acute Pancreatitis Acute pancreatitis, including fatal and non-fatal hemorrhagic or necrotizing pancreatitis, has been observed in patients treated with GLP-1 receptor agonists, including liraglutide [see Adverse Reactions (6)] . After initiation of liraglutide injection, observe patients carefully for signs and symptoms of acute pancreatitis which may include persistent or severe abdominal pain (sometimes radiating to the back) and which may or may not be accompanied by nausea or vomiting. If pancreatitis is suspected, discontinue liraglutide injection and initiate appropriate management. 5.3 Never Share a Liraglutide Injection Pen Between Patients Liraglutide injection pens must never be shared between patients, even if the needle is changed. Pen-sharing poses a risk for transmission of blood-borne pathogens. 5.4 Hypoglycemia Adult patients receiving liraglutide injection in combination with an insulin secretagogue (e.g., sulfonylurea) or insulin may have an increased risk of hypoglycemia, including severe hypoglycemia. In pediatric patients 10 years of age and older, the risk of hypoglycemia was higher with liraglutide injection regardless of insulin and/or metformin use. [see Adverse Reactions ( 6.1 ), Drug Interactions ( 7.2 )] . The risk of hypoglycemia may be lowered by a reduction in the dose of sulfonylurea (or other concomitantly administered insulin secretagogues) or insulin. Inform patients using these concomitant medications and pediatric patients of the risk of hypoglycemia and educate them on the signs and symptoms of hypoglycemia. 5.5 Acute Kidney Injury Due to Volume Depletion There have been postmarketing reports of acute kidney injury, in some cases requiring hemodialysis, in patients treated with liraglutide injection [see Adverse Reactions ( 6.2 )] . The majority of the reported events occurred in patients who experienced gastrointestinal reactions leading to dehydration such as nausea, vomiting, or diarrhea [see Adverse Reactions ( 6.1 )] . Monitor renal function in patients reporting adverse reactions to liraglutide injection that could lead to volume depletion, especially during dosage initiation and escalation of liraglutide injection [see Use in Specific Populations ( 8.6 )] . 5.6 Severe Gastrointestinal Adverse Reactions Use of GLP-1 receptor agonists, including liraglutide, has been associated with gastrointestinal adverse reactions, sometimes severe [see Adverse Reactions ( 6 )] . In liraglutide injection clinical trials, severe gastrointestinal adverse reactions were reported more frequently among patients receiving liraglutide injection (1.2 mg 4.4 %, 1.8 mg 4.2 %) than placebo (1.1 %). Severe gastrointestinal adverse reactions have also been reported postmarketing with GLP-1 receptor agonists. Liraglutide injection is not recommended in patients with severe gastroparesis. 5.7 Hypersensitivity Reactions There have been postmarketing reports of serious hypersensitivity reactions (e.g., anaphylactic reactions and angioedema) in patients treated with liraglutide injection [see Adverse Reactions ( 6.2 )] . If a hypersensitivity reaction occurs, discontinue liraglutide injection; treat promptly per standard of care, and monitor until signs and symptoms resolve. Anaphylaxis and angioedema have been reported with other GLP-1 receptor agonists. Use caution in a patient with a history of anaphylaxis or angioedema with another GLP-receptor agonist because it is unknown whether such patients will be predisposed to these reactions with liraglutide injection. Liraglutide injection is contraindicated in patients who have had a serious hypersensitivity reaction to liraglutide or any of the excipients in liraglutide injection [see Contraindications ( 4 )] . 5.8 Acute Gallbladder Disease Acute events of gallbladder disease such as cholelithiasis or cholecystitis have been reported in GLP-1 receptor agonist trials and postmarketing. If cholelithiasis is suspected, gallbladder studies and appropriate clinical follow-up are indicated. 5.9 Pulmonary Aspiration During General Anesthesia or Deep Sedation Liraglutide injection delays gastric emptying [see Clinical Pharmacology ( 12.2 )] . There have been rare postmarketing reports of pulmonary aspiration in patients receiving GLP-1 receptor agonists undergoing elective surgeries or procedures requiring general anesthesia or deep sedation who had residual gastric contents despite reported adherence to preoperative fasting recommendations. Available data are insufficient to inform recommendations to mitigate the risk of pulmonary aspiration during general anesthesia or deep sedation in patients taking liraglutide injection, including whether modifying preoperative fasting recommendations or temporarily discontinuing liraglutide injection could reduce the incidence of retained gastric contents. Instruct patients to inform healthcare providers prior to any planned surgeries or procedures if they are taking liraglutide injection.
