Risk of Thyroid C-cell Tumors: Counsel patients regarding the potential risk for MTC with the use of Zepbound 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 Zepbound. Such monitoring may increase the risk of unnecessary procedures, due to the low test specificity for serum calcitonin and a high background incidence of thyroid disease. Significantly elevated serum calcitonin values 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.

Acute Kidney Injury: Use of Zepbound has been associated with acute kidney injury, which can result from dehydration due to gastrointestinal adverse reactions to Zepbound, including nausea, vomiting, and diarrhea. In patients treated with GLP-1 receptor agonists,
there have been postmarketing reports of acute kidney injury and worsening of chronic renal failure, which may sometimes require hemodialysis.
Some of these events have been reported in patients without known underlying renal disease. A majority of the reported events occurred in patients who had experienced nausea, vomiting, diarrhea, or dehydration. Monitor renal function in patients reporting adverse reactions to Zepbound that could lead to volume depletion.
Improvements in cardiometabolic parameters at 72 weeks3,6
At 72 weeks, participants in the pooled Zepbound arm had a mean pulse rate increase of 1.8 beats/minute
compared to a mean baseline of 72.2 beats/minute. The placebo arm has a mean pulse rate increase of 0.1
beats/minute compared to a mean baseline of 72.9 beats/minute. Results were not adjusted for type I

In Zepbound clinical trials, gastrointestinal adverse reactions occurred more frequently among patients receiving Zepbound (5 mg 56%, 10 mg 56%, 15 mg 56%) than placebo (30%).1
Select Important Safety Information
Severe Gastrointestinal Adverse Reactions: Use of Zepbound has been associated with gastrointestinal adverse reactions, sometimes severe. In a pool of two Zepbound clinical trials (Study 1 and Study 2), severe gastrointestinal adverse reactions were reported more frequently among patients receiving Zepbound (5 mg 1.7%, 10 mg 2.5%, 15 mg 3.1%) than placebo (1.0%). Zepbound has not been studied in patients with severe gastrointestinal disease, including severe gastroparesis, and is therefore not recommended in these patients.
Acute Gallbladder Disease: Treatment with Zepbound and GLP-1 receptor agonists is associated with an increased occurrence of acute gallbladder disease.
In a pool of two clinical trials of Zepbound (Study 1 and Study 2), cholelithiasis was reported in 1.1% of Zepbound-treated patients and 1.0% of placebo-treated patients, cholecystitis was reported in 0.7% of Zepbound-treated patients and 0.2% of placebo-treated patients, and cholecystectomy was reported in 0.2% of Zepbound-treated patients and no placebo-treated patients. Acute gallbladder events were associated with weight reduction. If cholecystitis is suspected, gallbladder diagnostic studies and appropriate clinical follow-up are indicated.

SURMOUNT-1
SURMOUNT-1 was a 72-week, double-blind, placebo-controlled, phase 3 trial that randomized 2539 adult
patients with a body mass index (BMI) of ≥30 kg/m2 or ≥27 kg/m2 and at least 1
weight-related comorbid condition (study excluded patients with type I diabetes or type 2 diabetes), to
receive once-weekly subcutaneous Zepbound 5 mg, 10 mg, 15 mg, or placebo (1:1:1:1 ratio), including a
20-week dose-escalation period. Treatment was an adjunct to a reduced-calorie diet and increased physical
activity.* Mean baseline body weight for Zepbound 5 mg was 226.8 lb, for Zepbound 10 mg 233.3 lb, for
Zepbound 15 mg 232.8 lb, and for placebo 231.0 lb.1-3
Coprimary endpoints were to demonstrate that Zepbound 10 mg and/or 15 mg are superior to placebo for mean
percent change in body weight from baseline and percentage of study participants who achieved ≥5% body
weight reduction at 72 weeks.1,3
Secondary endpoints were assessed at 72 weeks: superiority of Zepbound 5 mg to placebo for mean
percent change in body weight and percentage of participants who achieved ≥5% body weight reduction;
superiority of Zepbound 10 mg and/or 15 mg to placebo for percentage of participants who achieved ≥10%
body
weight reduction, ≥15% body weight reduction, and/or ≥20% body weight reduction.3

Select Important Safety Information
Acute Pancreatitis: Acute pancreatitis, including fatal and non-fatal hemorrhagic or necrotizing pancreatitis, has been observed in patients treated with GLP-1 receptor agonists or tirzepatide. In clinical trials of tirzepatide for a different indication, 14 events of acute pancreatitis were confirmed by adjudication in 13 tirzepatide-treated patients (0.23 patients per 100 years of exposure) versus 3 events in 3 comparator-treated patients (0.11 patients per 100 years of exposure). In a pool of two Zepbound clinical trials (Study 1 and Study 2), 0.2% of Zepbound-treated patients had acute pancreatitis confirmed by adjudication (0.14 patients per 100 years of exposure) versus 0.2% of placebo-treated patients (0.15 patients per 100 years of exposure). Zepbound has not been studied in patients with a prior history of pancreatitis. It is unknown if patients with a history of pancreatitis are at higher risk for development of pancreatitis on Zepbound. Observe patients for signs and symptoms of pancreatitis, including persistent severe abdominal pain sometimes radiating to the back, which may or may not be accompanied by vomiting. If pancreatitis is suspected, discontinue Zepbound and initiate appropriate management. If the diagnosis of pancreatitis is confirmed, Zepbound should not be restarted.
SURMOUNT-2
SURMOUNT-2 was a 72-week, double-blind, placebo-controlled, phase 3 trial that randomized 938 adult
patients
with a body mass index (BMI) of ≥27 kg/m2 and type 2 diabetes to receive once-weekly
subcutaneous
Zepbound 10 mg, 15 mg, or placebo (1:1:1 ratio), including a 20-week dose-escalation period.
Treatment with Zepbound or placebo was an adjunct to a reduced-calorie diet and increased physical
activity.* Patients included in the trial were treated with diet and exercise alone or with any
oral anti-hyperglycemic agent except DPP-4 inhibitors or GLP-1 receptor agonists. Patients taking
injectable
therapies for type 2 diabetes were excluded from the study. Mean baseline body weight was 222.4 lb for
Zepbound 10 mg, 219.6 lb for Zepbound 15 mg, and 224.2 lb for placebo.1,4,8
Coprimary endpoints were to demonstrate that Zepbound 10 mg and/or 15 mg are superior to placebo for mean
percent change in body weight from baseline and percentage of study participants who achieved ≥5% body
weight reduction at 72 weeks.1
Some key secondary endpoints assessed at 72 weeks were superiority of Zepbound 10 mg and/or 15 mg to
placebo for percentage of participants who achieved ≥10%, ≥15%, and/or ≥20% body weight reduction: mean
change in A1C (%); percentage of participants who achieved A1C <7%; and mean change in fasting
glucose.1,8

In rats, tirzepatide causes dose-dependent and treatment-duration-dependent thyroid C-cell tumors at clinically relevant exposures. It is unknown whether Zepbound causes thyroid C-cell tumors, including medullary thyroid carcinoma (MTC), in humans as human relevance of tirzepatide-induced rodent thyroid C-cell tumors has not been determined.
Zepbound is contraindicated in patients with a personal or family history of MTC or in patients with Multiple Endocrine Neoplasia syndrome type 2 (MEN 2). Counsel patients regarding the potential risk for MTC with the use of Zepbound 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 Zepbound.
Contraindications:
Zepbound is contraindicated in patients with a personal or family history of MTC or in patients with MEN 2, and in patients with known serious hypersensitivity to tirzepatide or any of the excipients in Zepbound. Serious hypersensitivity reactions including anaphylaxis and angioedema have been reported with tirzepatide.
Risk of Thyroid C-cell Tumors: Counsel patients regarding the potential risk for MTC with the use of Zepbound 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 Zepbound. Such monitoring may increase the risk of unnecessary procedures, due to the low test specificity for serum calcitonin and a high background incidence of thyroid disease. Significantly elevated serum calcitonin values 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.
Severe Gastrointestinal Adverse Reactions: Use of Zepbound has been associated with gastrointestinal adverse reactions, sometimes severe. In a pool of two Zepbound clinical trials (Study 1 and Study 2), severe gastrointestinal adverse reactions were reported more frequently among patients receiving Zepbound (5 mg 1.7%, 10 mg 2.5%, 15 mg 3.1%) than placebo (1.0%). Zepbound has not been studied in patients with severe gastrointestinal disease, including severe gastroparesis, and is therefore not recommended in these patients.
Acute Kidney Injury: Use of Zepbound has been associated with acute kidney injury, which can result from dehydration due to gastrointestinal adverse reactions to Zepbound, including nausea, vomiting, and diarrhea. In patients treated with GLP-1 receptor agonists, there have been postmarketing reports of acute kidney injury and worsening of chronic renal failure, which may sometimes require hemodialysis. Some of these events have been reported in patients without known underlying renal disease. A majority of the reported events occurred in patients who had experienced nausea, vomiting, diarrhea, or dehydration. Monitor renal function in patients reporting adverse reactions to Zepbound that could lead to volume depletion.
Acute Gallbladder Disease: Treatment with Zepbound and GLP-1 receptor agonists is associated with an increased occurrence of acute gallbladder disease. In a pool of two clinical trials of Zepbound (Study 1 and Study 2), cholelithiasis was reported in 1.1% of Zepbound-treated patients and 1.0% of placebo-treated patients, cholecystitis was reported in 0.7% of Zepbound-treated patients and 0.2% of placebo-treated patients, and cholecystectomy was reported in 0.2% of Zepbound-treated patients and no placebo-treated patients. Acute gallbladder events were associated with weight reduction. If cholecystitis is suspected, gallbladder diagnostic studies and appropriate clinical follow-up are indicated.
Acute Pancreatitis: Acute pancreatitis, including fatal and non-fatal hemorrhagic or necrotizing pancreatitis, has been observed in patients treated with GLP-1 receptor agonists or tirzepatide. In clinical trials of tirzepatide for a different indication, 14 events of acute pancreatitis were confirmed by adjudication in 13 tirzepatide-treated patients (0.23 patients per 100 years of exposure) versus 3 events in 3 comparator-treated patients (0.11 patients per 100 years of exposure). In a pool of two Zepbound clinical trials (Study 1 and Study 2), 0.2% of Zepbound-treated patients had acute pancreatitis confirmed by adjudication (0.14 patients per 100 years of exposure) versus 0.2% of placebo-treated patients (0.15 patients per 100 years of exposure). Zepbound has not been studied in patients with a prior history of pancreatitis. It is unknown if patients with a history of pancreatitis are at higher risk for development of pancreatitis on Zepbound. Observe patients for signs and symptoms of pancreatitis, including persistent severe abdominal pain sometimes radiating to the back, which may or may not be accompanied by vomiting. If pancreatitis is suspected, discontinue Zepbound and initiate appropriate management. If the diagnosis of pancreatitis is confirmed, Zepbound should not be restarted.
Hypersensitivity Reactions: There have been postmarketing reports of serious hypersensitivity reactions (e.g., anaphylaxis, angioedema) in patients treated with tirzepatide. In a pool of two Zepbound clinical trials (Study 1 and Study 2), 0.1% of Zepbound-treated patients had severe hypersensitivity reactions compared to no placebo-treated patients. If hypersensitivity reactions occur, advise patients to promptly seek medical attention and discontinue use of Zepbound. Do not use in patients with a previous serious hypersensitivity reaction to tirzepatide or any of the excipients in Zepbound. Use caution in patients with a history of angioedema or anaphylaxis with a GLP-1 receptor agonist because it is unknown if such patients will be predisposed to these reactions with Zepbound.
Hypoglycemia: Zepbound lowers blood glucose and can cause hypoglycemia. In a trial of patients with type 2 diabetes mellitus and BMI ≥27 kg/m2 (Study 2), hypoglycemia (plasma glucose <54 mg/dL) was reported in 4.2% of Zepbound-treated patients versus 1.3% of placebo-treated patients. In this trial, patients taking Zepbound in combination with an insulin secretagogue (e.g., sulfonylurea) had increased risk of hypoglycemia (10.3%) compared to Zepbound-treated patients not taking a sulfonylurea (2.1%). There is also increased risk of hypoglycemia in patients treated with tirzepatide in combination with insulin. Hypoglycemia has also been associated with Zepbound and GLP-1 receptor agonists in adults without type 2 diabetes mellitus. Inform patients of the risk of hypoglycemia and educate them on the signs and symptoms of hypoglycemia. In patients with diabetes mellitus, monitor blood glucose prior to starting Zepbound and during Zepbound treatment. The risk of hypoglycemia may be lowered by a reduction in the dose of insulin or sulfonylurea (or other concomitantly administered insulin secretagogue).
Diabetic Retinopathy Complications in Patients with Type 2 Diabetes Mellitus: Rapid improvement in glucose control has been associated with a temporary worsening of diabetic retinopathy. Tirzepatide has not been studied in patients with non-proliferative diabetic retinopathy requiring acute therapy, proliferative diabetic retinopathy, or diabetic macular edema. Patients with a history of diabetic retinopathy should be monitored for progression of diabetic retinopathy.
Suicidal Behavior and Ideation: Suicidal behavior and ideation have been reported in clinical trials with other weight management products. Monitor patients treated with Zepbound for the emergence or worsening of depression, suicidal thoughts or behaviors, and/or any unusual changes in mood or behavior. Discontinue Zepbound in patients who experience suicidal thoughts or behaviors. Avoid Zepbound in patients with a history of suicidal attempts or active suicidal ideation.
Pulmonary Aspiration During General Anesthesia or Deep Sedation: Zepbound delays gastric emptying. 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 Zepbound, including whether modifying preoperative fasting recommendations or temporarily discontinuing Zepbound 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 Zepbound.
Most common adverse reactions: The most common adverse reactions reported in ≥5% of patients treated with Zepbound are nausea, diarrhea, vomiting, constipation, abdominal pain, dyspepsia, injection site reactions, fatigue, hypersensitivity reactions, eructation, hair loss, and gastroesophageal reflux disease.
Drug Interactions: Zepbound lowers blood glucose. When initiating Zepbound, consider reducing the dose of concomitantly administered insulin or insulin secretagogues (e.g., sulfonylureas) to reduce the risk of hypoglycemia. Zepbound delays gastric emptying and thereby has the potential to impact the absorption of concomitantly administered oral medications. Caution should be exercised when oral medications are concomitantly administered with Zepbound. Monitor patients on oral medications dependent on threshold concentrations for efficacy and those with a narrow therapeutic index (e.g., warfarin) when concomitantly administered with Zepbound.
Pregnancy: Advise pregnant patients that weight loss is not recommended during pregnancy and to discontinue Zepbound when a pregnancy is recognized. Available data with tirzepatide in pregnant patients are insufficient to evaluate for a drug-related risk of major birth defects, miscarriage, or other adverse maternal or fetal outcomes. Based on animal reproduction studies, there may be risks to the fetus from exposure to tirzepatide during pregnancy. There will be a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to Zepbound (tirzepatide) during pregnancy.
Pregnant patients exposed to Zepbound and healthcare providers are
encouraged to contact Eli Lilly and Company at 1-800-LillyRx
(1-800-545-5979).
Lactation: There are no data on the presence of tirzepatide or its metabolites in animal or human milk, the effects on the breastfed infant, or the effects on milk production. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for Zepbound and any potential adverse effects on the breastfed infant from Zepbound or from the underlying maternal condition.
Females and Males of Reproductive Potential: Use of Zepbound may reduce the efficacy of oral hormonal contraceptives due to delayed gastric emptying. This delay is largest after the first dose and diminishes over time. Advise patients using oral hormonal contraceptives to switch to a non-oral contraceptive method, or add a barrier method of contraception, for 4 weeks after initiation with Zepbound and for 4 weeks after each dose escalation.
Pediatric Use: The safety and effectiveness of Zepbound have not been established in pediatric patients.
Zepbound is indicated in combination with a reduced-calorie diet and increased physical activity to reduce excess body weight and maintain weight reduction long term in adults with obesity or adults with overweight in the presence of at least one weight-related comorbid condition.
Limitations of Use
Zepbound contains tirzepatide. Coadministration with other tirzepatide-containing products or with any glucagon-like peptide-1 (GLP-1) receptor agonist is not recommended.
