Trulicity (dulaglutide) is a glucagon-like peptide-1 (GLP-1) agonist that helps control blood sugar in people 10 years and older with Type 2 diabetes. It's also approved to lower the risk of heart problems like heart attacks, strokes, and heart-related death in certain adults with Type 2 diabetes. The medication is injected under the skin once a week. Common side effects include nausea, vomiting, diarrhea, and stomach pain. When taken with certain diabetes medications like insulin, there's a higher risk of low blood sugar (hypoglycemia).

Trulicity (dulaglutide) is a glucagon-like peptide-1 (GLP-1) receptor agonist. It acts like the natural GLP-1 hormone in the body. This hormone lowers blood sugar by helping your pancreas release more insulin, stopping your liver from releasing more sugar, and slowing digestion.

Ask your prescriber how often you should check your blood sugar while using Trulicity (dulaglutide). Keep track of your readings and share them with your care team so they can adjust your dose if needed.
Using Trulicity (dulaglutide) with certain diabetes medications, like insulin, can raise your risk of low blood sugar (hypoglycemia). Learn to recognize symptoms like sweating, shakiness, anxiety, and hunger, and know how to treat it.
Trulicity (dulaglutide) can cause stomach-related side effects like nausea, vomiting, and diarrhea. If these symptoms become severe or don’t go away, contact your prescriber.
Drink plenty of fluids while using Trulicity (dulaglutide) to help prevent dehydration, especially if you experience stomach-related side effects. Serious cases of dehydration can also lead to kidney problems.
Tell your prescriber right away if you have severe stomach pain that doesn’t go away, especially if it spreads to your back. This could be a sign of pancreatitis, a serious condition that causes inflammation of the pancreas.
Store unopened Trulicity (dulaglutide) pens in the refrigerator. You can also keep them out at room temperature (below 86°F) for up to 14 days. Don't freeze your pens because this might damage the medication. If a pen is frozen, throw it away and use a new one.
The Instructions for Use that come with your medication provide detailed steps on how to use your Trulicity (dulaglutide) pen. You can also watch an instructional video. If you have questions, contact a member of your healthcare team
Each Trulicity (dulaglutide) pen is single-use and provides one dose. You can inject it at any time of day, with or without food.
Inject Trulicity (dulaglutide) under the skin of your stomach or thigh. If someone else is giving the injection, they can also use the back of your upper arm. Rotate injection sites each week to avoid skin irritation or damage.
If you miss a dose of Trulicity (dulaglutide) and your next dose is at least 3 days away, inject the missed dose as soon as you remember, then continue your usual weekly schedule. If your next dose is less than 3 days away, skip the missed dose and inject your next dose on schedule. Don't take two doses within 3 days since this can lead to side effects.
If you drop your Trulicity (dulaglutide) pen, don't use it. Some parts of the pen contain glass, which can break. Use a new pen instead.
After you inject your dose, throw away the Trulicity (dulaglutide) pen and needle in a sharps container or a sturdy plastic container, such as an empty milk carton or laundry detergent bottle. Don't throw them in the trash.
Trulicity (dulaglutide) can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
Risk factors: Personal or family history of medullary thyroid carcinoma (MTC) | Multiple Endocrine Neoplasia syndrome type 2 (MEN 2)
Animal studies show that Trulicity (dulaglutide) causes thyroid tumors in rats and mice, but it's unclear if it has the same effect in humans. To be safe, don't use Trulicity (dulaglutide) if you or a family member has had medullary thyroid cancer (MTC) or Multiple Endocrine Neoplasia syndrome type 2 (MEN 2). Let your prescriber know if you notice a lump on your neck, trouble breathing or swallowing, or hoarseness that won't go away, as these might be signs of thyroid cancer. If you’re worried about this risk, talk to your prescriber.
Risk factors: Higher doses of Trulicity (dulaglutide)
In some rare cases, people taking Trulicity (dulaglutide) have had pancreatitis, a serious condition that causes inflammation of the pancreas. Watch for signs of pancreatitis, including severe stomach pain that can spread to your back, with or without vomiting. If you have these symptoms, stop using Trulicity (dulaglutide) right away and contact your prescriber.
Risk factors: Also using insulin, sulfonylureas, or glinides
If you take Trulicity (dulaglutide) with insulin, a sulfonylurea (e.g. glipizide), or a glinides (e,g., repaglinide), you have a higher risk of low blood sugar (hypoglycemia), including severe cases.
Your prescriber might need to lower the dose of insulin, the sulfonylurea, or the repaglinide to help reduce this risk. Learn to recognize the signs of low blood sugar, such as shakiness, sweating, dizziness, confusion, hunger, or weakness. If you're concerned about your blood sugar levels or need help monitoring them, talk to your prescriber.
Some people taking Trulicity (dulaglutide) have had severe allergic reactions, including anaphylaxis and angioedema (swelling under the skin). If you develop swelling of the face, lips, throat, or trouble breathing, stop using Trulicity (dulaglutide) immediately and get emergency medical help.
Risk factors: History of kidney problems | Dehydration
Some people taking Trulicity (dulaglutide) developed new or worsening kidney problems, known as acute kidney injury. In some cases, treatment required dialysis, even in people who had no previous kidney problems. Most of the time, this happened in people who had nausea, vomiting, diarrhea, or dehydration after taking the medication.
If you have kidney problems or develop severe stomach-related side effects while using Trulicity (dulaglutide), your prescriber might check your kidney labs. To prevent kidney damage, drink plenty of fluids during treatment to stay hydrated. Tell your prescriber if you have trouble urinating or if you're not urinating as much as usual while taking this medication.
Using Trulicity (dulaglutide) can cause stomach-related side effects like nausea, vomiting, and diarrhea, and in some cases, they can be severe. Because Trulicity (dulaglutide) hasn't been studied in people with severe stomach conditions, it's not recommended if you have gastroparesis (slow stomach emptying). If you have a history of stomach problems, talk to your prescriber before using this medication.
Risk factors: History of diabetic retinopathy | Rapid improvement in managing blood sugar levels
Some people using Trulicity (dulaglutide) have reported diabetic retinopathy complications during treatment. If you already have diabetic retinopathy, your prescriber will check your eyes to make sure it doesn't get worse. Get medical attention if you notice changes in your vision or eye pain.
Some people using Trulicity (dulaglutide) have developed gallbladder problems like gallstones. Contact your prescriber right away if you have severe stomach pain, nausea, vomiting, or yellowing of the skin or eyes. They might need to run blood tests to check your gallbladder.
Trulicity (dulaglutide) slows down digestion, which can make food stay in your stomach longer. Rare cases have been reported where people taking GLP-1 medications like Trulicity (dulaglutide) breathed fluid into the lungs during general anesthesia or deep sedation. Tell your prescriber before any surgery or procedure if you're taking this medication.
Trulicity (dulaglutide) is injected under the skin in the stomach or thigh. If someone else is giving you the injection, they can also use the back of your upper arm.
You start with a low dose, and after at least 4 weeks, your prescriber might raise it if you need better blood sugar control. If you have stomach-related side effects, your prescriber might lower your dose.
Adults: The typical starting dose is 0.75 mg once a week. The maximum dose is 4.5 mg once a week.
Children: The typical starting dose is 0.75 mg once a week. The maximum dose is 1.5 mg once a week.
