Missed doses: If a dose is missed, administer as soon as possible within 3 days after the missed dose; dosing can then be resumed on the usual day of administration. If there are less than 3 days until next scheduled dose, omit the missed dose and resume administration at the next regularly scheduled weekly dose.
Refer to adult dosing.
Dosing: Renal Impairment
No dosage adjustment necessary; use caution when initiating or escalating doses.
Dosing: Hepatic Impairment
There are no dosage adjustments provided in the manufacturer’s labeling; use with caution
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.

Concerns related to adverse effects:
• Cardiovascular effects: Tachycardia, PR interval prolongation, and first-degree AV block have been observed; use caution in patients with, or at risk (eg, preexisting conduction system abnormalities, underlying structural heart disease, ischemic heart disease, cardiomyopathies) for developing conduction abnormalities.
• Hypersensitivity reactions: Hypersensitivity reactions have been reported; discontinue therapy in the event of a hypersensitivity reaction.
• 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 glucagon-like peptide-1 (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 (MEN2). Cases of MTC in humans have been reported in patients treated with the GLP-1 receptor agonist liraglutide. 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.
• Gastrointestinal disease: Use is not recommended in patients with preexisting severe gastrointestinal 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 pre-existing renal disease. A majority of reported cases occurred in patients with nausea/vomiting/diarrhea or dehydration.
Concurrent drug therapy issues:
• Drug-drug interactions: Potentially significant interactions may exist, requiring dose or frequency adjustment, additional monitoring, and/or selection of alternative therapy. Consult drug interactions database for more detailed information.
• 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 (DSME) 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 2016a]), renal function, signs/symptoms of pancreatitis
Pregnancy Risk Factor
The Canadian labeling contraindicates use during pregnancy and recommends that women discontinue therapy at least 1 month before attempting to conceive.
Adverse events have been observed in some animal reproduction studies.
In women with diabetes, maternal hyperglycemia can be associated with congenital malformations as well as adverse effects in the fetus, neonate, and the mother (ACOG 2005; ADA 2015; Kitzmiller 2008; Metzger 2007). 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 (ACOG 2013; ADA 2015; Blumer 2013; Kitzmiller 2008). Prior to pregnancy, effective contraception should be used until glycemic control is achieved (Kitzmiller 2008). Other agents are currently recommended to treat diabetes in pregnant women (ACOG 2013; Blumer 2013).
• Discuss specific use of drug and side effects with patient as it relates to treatment. (HCAHPS: During this hospital stay, were you given any medicine that you had not taken before? Before giving you any new medicine, how often did hospital staff tell you what the medicine was for? How often did hospital staff describe possible side effects in a way you could understand?)
• Patient may experience lack of appetite or loss of strength and energy. Have patient report immediately to prescriber signs of thyroid cancer (new lump or swelling in the neck, pain in the front of the neck, cough that does not go away, change in voice that does not go away like hoarseness, or trouble swallowing or breathing), signs of a pancreas problem (pancreatitis; severe abdominal pain, severe back pain, severe nausea, vomiting), signs of low blood sugar (dizziness, headache, fatigue, feeling weak, shaking, a fast heartbeat, confusion, hunger, or sweating), urinary retention, change in amount of urine passed, severe diarrhea, severe nausea, vomiting, or severe abdominal pain (HCAHPS).
• Educate patient about signs of a significant reaction (eg, wheezing; chest tightness; fever; itching; bad cough; blue skin color; seizures; or swelling of face, lips, tongue, or throat). Note: This is not a comprehensive list of all side effects. Patient should consult prescriber for additional questions.
