my body is truly powerful. i have the power to lower my blood sugar and a1c. because i can still make my own insulin. and trulicity activates my body to release it like it's supposed to. trulicity is for people with type 2 diabetes. it's not insulin. i take it once a week. it starts acting in my body from the first dose. trulicity isn't for people with type 1 diabetes or diabetic ketoacidosis. don't take trulicity if you're allergic to it, you or your family have medullary thyroid cancer, or have multiple endocrine neoplasia syndrome type 2. stop trulicity and call your doctor right away if you have an allergic reaction, a lump or swelling in your neck, or severe stomach pain. serious side effects may include pancreatitis. taking trulicity with a sulfonylurea or insulin increases low blood sugar risk. side effects include nausea, diarrhea, vomiting, belly pain, and decreased appetite, which lead to dehydration and may worsen kidney problems.
