Use: Labeled Indications
Diabetes mellitus, type 2, treatment: As an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes mellitus; risk reduction of major cardiovascular events (cardiovascular death, nonfatal myocardial infarction, nonfatal stroke) in adults with type 2 diabetes mellitus who have established cardiovascular disease or multiple cardiovascular risk factors.
Serious hypersensitivity to dulaglutide or any component of the formulation; personal or family history of medullary thyroid carcinoma (MTC); patients with multiple endocrine neoplasia syndrome type 2 (MEN2)
Canadian labeling: Additional contraindications (not in US labeling): Pregnancy; breast-feeding
Note: Due to lack of additive glycemic benefit, avoid concomitant use with a dipeptidyl peptidase-4 inhibitor (ADA/EASD [Davies 2018]). May require a dose reduction of insulin and/or insulin secretagogues to avoid hypoglycemia.
Diabetes mellitus, type 2, treatment:
Note: May be used as an adjunctive agent or alternative monotherapy for patients who fail initial therapy with lifestyle intervention and metformin or who cannot take metformin. May be preferred in patients who have or are at risk for atherosclerotic cardiovascular disease, when weight loss is desired, and/or in patients with an HbA1c relatively far from goal (eg, HbA1c 9% to 10%) and type 1 diabetes is not likely (ADA 2020; Gerstein 2019; Wexler 2020).
SubQ: Initial: 0.75 mg once weekly; may increase to 1.5 mg once weekly after 4 to 8 weeks if needed to achieve glycemic goals (Dungan 2020; Umpierrez 2014; Weinstock 2015). If additional glycemic control is needed, may further increase to 3 mg once weekly after at least 4 weeks on the 1.5 mg weekly dose and then to a maximum of 4.5 mg once weekly after at least 4 weeks on the 3 mg weekly dose.
Missed doses: Missed dose should be administered as soon as possible within 3 days; resume usual schedule thereafter. If there are <3 days until next scheduled dose, omit the missed dose and resume administration at the next scheduled weekly dose.
Dosage adjustment for concomitant therapy: Significant drug interactions exist, requiring dose/frequency adjustment or avoidance. Consult drug interactions database for more information.
Refer to adult dosing.
SubQ: Do not inject intravenously or intramuscularly. Inject subcutaneously into the upper arm, thigh, or abdomen; when administering within the same body region, use a different injection site each week. Administer once weekly on the same day each week, without regard to meals or time of day. The day of weekly administration may be changed, as long as the last dose was administered ≥3 days before. If using concomitantly with insulin, administer as separate injections (do not mix); may inject in the same body region as insulin, but not adjacent to one another.
Individualized medical nutrition therapy (MNT) based on ADA recommendations is an integral part of therapy.
Store at 36°F to 46°F (2°C to 8°C). Do not freeze. Protect from light. If needed, each single-dose pen or prefilled syringe can be kept at room temperature, not to exceed 86°F (30°C) for a total of 14 days.

ALERT: U.S. Boxed WarningRisk of thyroid C-cell tumors:
In male and female rats, dulaglutide causes a dose-related and treatment-duration-dependent increase in the incidence of thyroid C-cell tumors (adenomas and carcinomas) after lifetime exposure. It is unknown whether dulaglutide causes thyroid C-cell tumors, including medullary thyroid carcinoma (MTC), in humans as human relevance of dulaglutide-induced rodent thyroid C-cell tumors has not been determined.
Dulaglutide is contraindicated in patients with a personal or family history of MTC and in patients with multiple endocrine neoplasia syndrome type 2 (MEN 2). Counsel patients regarding the potential risk of MTC with use of dulaglutide and inform them of symptoms of thyroid tumors (eg, mass in the neck, dysphagia, dyspnea, persistent hoarseness). Routine monitoring of serum calcitonin or using thyroid ultrasound monitoring is of uncertain value for early detection of MTC in patients treated with dulaglutide.
Concerns related to adverse effects:
• Gallbladder disease: Use of glucagon-like peptide-1 (GLP-1) agonists may increase risk of gallbladder and bile duct disease, including cholelithiasis and cholecystitis (Faillie 2016; Gerstein 2019; Monami 2017).
• Hypersensitivity reactions: Serious hypersensitivity reactions, including anaphylactic reactions and angioedema, have been reported; discontinue therapy in the event of a hypersensitivity reaction. Use with caution in patients with a history of angioedema or anaphylaxis to other GLP-1 receptor agonists; potential for cross-sensitivity is unknown.
• Pancreatitis: Cases of pancreatitis have been reported; monitor for signs and symptoms of pancreatitis (eg, persistent severe abdominal pain). If pancreatitis is suspected, discontinue use. Do not resume therapy if pancreatitis is confirmed. Consider antidiabetic therapies other than dulaglutide in patients with a history of pancreatitis.
• Thyroid tumors:[US Boxed Warning] Thyroid C-cell tumors have developed in animal studies with GLP-1 receptor agonists; it is not known if dulaglutide causes thyroid C-cell tumor, including medullary thyroid carcinoma (MTC) in humans. Routine monitoring of serum calcitonin or using thyroid ultrasound monitoring is of uncertain value for early detection of MTC in patients treated with dulaglutide. Patients should be counseled on the potential risk of MTC with the use of dulaglutide and informed of symptoms of thyroid tumors (eg, neck mass, dysphagia, dyspnea, persistent hoarseness). Use is contraindicated in patients with a personal or a family history of MTC and in patients with multiple endocrine neoplasia syndrome type 2. Once case of MTC has been reported in a patient treated with dulaglutide and cases have also been reported in patients treated with the GLP-1 receptor agonist liraglutide; data is insufficient to establish or exclude a causal relationship. Consultation with an endocrinologist is recommended in patients with thyroid nodules on physical examination or neck imaging and in patients who develop elevated calcitonin concentrations.
• Bariatric surgery:
- Dehydration: Evaluate, correct, and maintain postsurgical fluid requirements and volume status prior to initiating therapy, and closely monitor the patient for the duration of therapy; acute and chronic kidney failure exacerbation may occur. A majority of cases occurred in patients with nausea, vomiting, diarrhea, and/or dehydration. Nausea is common and fluid intake may be more difficult after gastric bypass, sleeve gastrectomy, and gastric band (Mechanick 2013).
- Excessive glucagon-like peptide-1 exposure: Closely monitor for efficacy and assess for signs and symptoms of pancreatitis if therapy is initiated after surgery; gastric bypass and sleeve gastrectomy (but not gastric band) significantly increase endogenous postprandial GLP-1 concentrations (Korner 2009; Peterli 2012). Administration of exogenous GLP-1 agonists may be redundant to surgery effects.
• Diabetic retinopathy: Increased complications associated with diabetic retinopathy have been observed with dulaglutide compared to placebo; risk may be increased in patients with a history of diabetic retinopathy. Monitor for worsening of diabetic retinopathy in patients with a prior history.
• GI disease: Use is not recommended in patients with preexisting severe GI disease, including severe gastroparesis.
• Hepatic impairment: Use with caution in patients with hepatic impairment.
• Renal impairment: Use with caution in patients with renal impairment, particularly during initiation of therapy and dose escalation. Acute renal failure and chronic renal failure exacerbation (sometimes requiring hemodialysis) have been reported; some cases have been reported in patients with no known preexisting renal disease. A majority of reported cases occurred in patients with nausea/vomiting/diarrhea or dehydration.
• Appropriate use: Diabetes mellitus: Not recommended for first-line therapy in patients inadequately controlled on diet and exercise alone. Do not use in patients with type 1 diabetes mellitus or for the treatment of diabetic ketoacidosis; not a substitute for insulin.
• Patient education: Diabetes self-management education is essential to maximize the effectiveness of therapy.
Plasma glucose, HbA1c (at least twice yearly in patients who have stable glycemic control and are meeting treatment goals; quarterly in patients not meeting treatment goals or with therapy change [ADA 2020]), renal function (in patients reporting severe GI reactions), signs/symptoms of pancreatitis
Poorly controlled diabetes during pregnancy can be associated with an increased risk of adverse maternal and fetal outcomes, including diabetic ketoacidosis, preeclampsia, spontaneous abortion, preterm delivery, delivery complications, major birth defects, stillbirth, and macrosomia (ACOG 201 2018). To prevent adverse outcomes, prior to conception and throughout pregnancy, maternal blood glucose and HbA1c should be kept as close to target goals as possible but without causing significant hypoglycemia (ADA 2020; Blumer 2013).
Agents other than dulaglutide are currently recommended to treat diabetes mellitus in pregnancy (ADA 2020).
