What Is Trulicity and How Does It Work?
Trulicity, known generically as dulaglutide, is a prescription biological medication designed to help adults manage type 2 diabetes. It belongs to a class of drugs called glucagon-like peptide-1 (GLP-1) receptor agonists. By mimicking natural hormones, Trulicity stimulates the pancreas to release insulin when blood sugar levels are high, slows down digestion to prevent post-meal sugar spikes, and reduces the amount of sugar released by the liver.
In addition to blood sugar management, Trulicity is prescribed to lower the risk of major cardiovascular events, such as heart attacks or strokes, in adults with type 2 diabetes who also have established heart disease or multiple cardiovascular risk factors.
Recommended Dosage and Administration
Trulicity is administered as a subcutaneous injection once a week, on the same day each week. It comes in single-dose, prefilled injection pens, making self-administration straightforward. The typical starting dose is 0.75 mg per week. Depending on individual blood sugar responses and tolerability, a healthcare provider may gradually increase the weekly dose up to a maximum of 4.5 mg.
The injection can be administered in the abdomen, thigh, or upper arm. It is highly recommended to rotate injection sites with each dose to avoid skin irritation. If a dose is missed, it should be taken as soon as possible, provided the next scheduled dose is at least three days away.
Potential Side Effects and Safety Warnings
Like many medications, Trulicity can cause side effects, particularly during the first few weeks of treatment. The most common mild side effects are gastrointestinal, including nausea, vomiting, diarrhea, abdominal pain, constipation, and decreased appetite. These symptoms often subside as the body adjusts to the medication.
However, serious side effects can occur. These include acute pancreatitis, severe hypoglycemia when used alongside other diabetes medications like insulin or sulfonylureas, acute gallbladder disease, and kidney impairment. Trulicity also carries a boxed warning regarding the potential risk of thyroid C-cell tumors. Individuals with a personal or family history of medullary thyroid carcinoma or Multiple Endocrine Neoplasia syndrome type 2 should not use this medication.
Drug Interactions and Precautions
Before starting Trulicity, it is essential to discuss your complete medical history with a healthcare professional. Trulicity slows gastric emptying, which may affect the absorption of oral medications taken at the same time. It can also interact with other diabetes therapies, increasing the risk of low blood sugar.
Special precautions apply to individuals with a history of diabetic retinopathy, severe gastrointestinal diseases like gastroparesis, or kidney and liver impairment. The safety of Trulicity during pregnancy and breastfeeding remains unestablished, so consultation with a doctor is necessary for those planning a pregnancy.
Proper Storage and Handling
To maintain its efficacy, Trulicity must be stored correctly. Unused injection pens should be kept in the refrigerator between 36 degrees Fahrenheit and 46 degrees Fahrenheit. If necessary, individual pens can be kept unrefrigerated at room temperature up to 86 degrees Fahrenheit for up to 14 days. Pens must never be frozen or exposed to extreme heat or direct sunlight.
