Dulaglutide
dulaglutide · Say it: doo-la-GLOO-tide
A once-weekly injection used with diet and exercise to lower blood sugar in type 2 diabetes. Its boxed warning is about thyroid C-cell tumors.
Brand names: Trulicity
⬛ Boxed warning (the FDA's strongest warning)
The boxed warning is about the risk of thyroid C-cell tumors. In rats, dulaglutide caused an increase in thyroid C-cell tumors, including adenomas and carcinomas, after lifetime exposure. The label says it is unknown whether dulaglutide causes thyroid C-cell tumors, including medullary thyroid carcinoma (MTC), in humans. Dulaglutide is contraindicated (should not be used) in people with a personal or family history of MTC, or with Multiple Endocrine Neoplasia syndrome type 2 (MEN 2). The label says patients should be told about the potential risk of MTC and about symptoms of thyroid tumors, such as a mass in the neck, trouble swallowing, shortness of breath, or persistent hoarseness. The label also says that routine blood tests (calcitonin) or thyroid ultrasounds are of uncertain value for finding MTC early.
Used for

The label says it is not known if it is safe and effective to lower blood sugar in children under 10.

💊 What is Dulaglutide used for?
- The label says dulaglutide is used along with diet and exercise to improve blood sugar (glucose) in adults and children 10 years of age and older with type 2 diabetes. It is also used to reduce the risk of major cardiovascular events, such as death, heart attack, or stroke, in adults with type 2 diabetes who have known heart disease or multiple cardiovascular risk factors. The label says it is not known if it is safe and effective to lower blood sugar in children under 10.
How it works
The label describes dulaglutide as a GLP-1 receptor agonist, a human-made protein that is similar to the natural GLP-1 hormone. The label says it delays stomach emptying, which can change how quickly other oral medicines are absorbed.
How it is usually taken
- The label says it is injected under the skin of the stomach (abdomen), thigh, or upper arm. It is not to be injected into a muscle or a vein. It is taken once a week, on the same day each week, at any time of day, with or without food. The label says the day of the week can be changed as long as the last dose was given 3 or more days earlier. The injection site should be rotated with each weekly injection. Do not mix it with insulin in the same injection. The label says a healthcare provider should show you how to use it before your first use, and that you should read the Instructions for Use that comes with it. Follow the instructions from your prescriber or pharmacist.
