Trulicity is a prescription medication primarily used to help manage blood sugar levels in adults with type 2 diabetes. It is also prescribed to reduce the risk of major cardiovascular events in adults with type 2 diabetes who have established cardiovascular disease or multiple cardiovascular risk factors. This medication is administered as a weekly injection under the skin.
How Trulicity Works
Trulicity contains the active ingredient dulaglutide, which is a glucagon-like peptide-1 (GLP-1) receptor agonist. This class of drugs works by mimicking the action of a natural hormone in the body. Trulicity helps the pancreas release more insulin when blood sugar levels are high, slows down the rate at which food leaves the stomach, and reduces the amount of sugar produced by the liver. These combined actions contribute to better blood sugar control and a reduced risk of heart problems.
Approved Uses for Trulicity
Trulicity is approved for adults with type 2 diabetes to:
- Improve blood sugar control when used in conjunction with diet and exercise.
- Lower the risk of major adverse cardiovascular events, such as heart attack or stroke, in individuals with type 2 diabetes who have existing heart disease or risk factors for heart disease.
It is important to note that Trulicity is not used to treat type 1 diabetes.
Dosage and Administration
Trulicity is available as a liquid solution in single-dose, prefilled injection pens. Common strengths include 0.75 mg/mL, 1.5 mg/mL, 3 mg/mL, and 4.5 mg/mL. The typical starting dose is 0.75 mg, administered once weekly. The dosage may be adjusted by a healthcare professional based on individual blood sugar levels and treatment response, up to a maximum of 4.5 mg per week. Injections are given under the skin in the abdomen, thigh, or upper arm, rotating injection sites each week.
Potential Side Effects
Like all medications, Trulicity can cause side effects, which can be mild or serious.
Mild Side Effects
Common mild side effects reported include abdominal pain, burping, constipation or diarrhea, fatigue, indigestion, injection-site reactions (such as rash, bruising, or pain), loss of appetite, nausea, vomiting, and weight loss. These often resolve within a few days or weeks, but a doctor or pharmacist should be consulted if they become bothersome.
Serious Side Effects
Serious side effects are less common but can occur. These may include low blood sugar levels, problems with kidney function, severe digestive issues (e.g., persistent vomiting or diarrhea), acute gallbladder disease (cholecystitis, gallstones), and pancreatitis (inflammation of the pancreas). Immediate medical attention is necessary for severe symptoms.
Boxed Warning: Risk of Thyroid Cancer
Trulicity carries a boxed warning regarding the potential risk of thyroid C-cell tumors, including medullary thyroid carcinoma (MTC). This risk was observed in animal studies, and while it’s not confirmed in humans, individuals with a personal or family history of MTC or Multiple Endocrine Neoplasia syndrome type 2 (MEN 2) should not use Trulicity. Symptoms such as a lump in the neck, hoarseness, trouble swallowing, or shortness of breath should be reported to a doctor.
Interactions and Precautions
Trulicity can interact with certain other medications, particularly other diabetes drugs like sulfonylureas and insulins, potentially increasing the risk of low blood sugar. It may also affect the absorption of orally administered medications. Patients should inform their doctor and pharmacist about all medications, supplements, and herbal products they are taking.
While there are no specific foods to avoid, Trulicity should be used as part of a balanced diet and exercise plan. Alcohol can affect blood sugar levels, so moderation or avoidance may be advised. Precautions also apply to individuals with a history of diabetic retinopathy, gastroparesis or other severe digestive problems, gallbladder disease, kidney problems, liver problems, or pancreatitis. Trulicity may slow gastric emptying, which is a consideration before any planned surgery or sedation.
Cost and Storage
The cost of Trulicity can vary based on insurance coverage and pharmacy. Information on potential savings programs may be available from the manufacturer. Trulicity pens should be stored in the refrigerator between 36°F and 46°F (2°C to 8°C) until the expiration date. If necessary, it can be kept unrefrigerated for up to 14 days at temperatures not exceeding 86°F (30°C).
Common Questions About Trulicity
Is Trulicity Used for Weight Loss?
Trulicity is not specifically approved for weight loss. However, some individuals may experience weight loss as a side effect due to reduced appetite or digestive issues. For weight management, a doctor can provide personalized guidance.
Is Trulicity a Type of Insulin?
No, Trulicity is not insulin. While insulin directly replaces or supplements the body’s natural insulin, Trulicity works by stimulating the body to release more of its own insulin and by other mechanisms to lower blood sugar.
How Does Trulicity Compare to Other Medications?
Trulicity belongs to the same class of GLP-1 receptor agonists as medications like Ozempic and Victoza, which are also injectable treatments for type 2 diabetes and cardiovascular risk reduction. It differs from oral medications like metformin or glipizide in its mechanism and administration.
What Happens if a Dose is Missed?
If a dose is missed and the next scheduled dose is at least 3 days away, the missed dose should be taken as soon as remembered. If the next dose is due in less than 3 days, the missed dose should be skipped, and the regular schedule resumed. Consult a doctor or pharmacist for specific advice.
Can Trulicity Cause Hair Loss, Joint Pain, Back Pain, or Depression?
Hair loss, joint pain, and depression were not commonly reported in studies of Trulicity. However, these conditions can be associated with diabetes itself. Back pain could be a symptom of pancreatitis, a rare but serious side effect of Trulicity. Any new or worsening symptoms should be discussed with a healthcare professional.
What Happens When Stopping Trulicity?
There are no known withdrawal side effects from suddenly stopping Trulicity. However, blood sugar levels are likely to increase. Patients wishing to discontinue Trulicity should consult their doctor to discuss alternative treatments.
