Key takeaways
Victoza (liraglutide) and Trulicity (dulaglutide) are both injectable medications used to manage Type 2 diabetes, but they have some key differences. Victoza is injected once daily, while Trulicity is injected once a week, which might be more convenient for some people. Both medications are GLP-1 agonists that help lower blood sugar by increasing insulin release, reducing sugar production, and slowing digestion. They also lower the risk of major heart events in adults with Type 2 diabetes and heart disease. Common side effects for both include nausea, vomiting, and diarrhea. They both carry an increased risk of thyroid cancer, so they’re not recommended for people with a personal or family history of medullary thyroid carcinoma (MTC) or Multiple Endocrine Neoplasia syndrome type 2 (MEN 2).
