About Trulicity: Dulaglutide is used with a proper diet and exercise program to control high blood sugar in people with type 2 diabetes. Show more ▾

Controlling high blood sugar helps prevent kidney damage, blindness, nerve problems, loss of limbs, and sexual function problems. This medication is also used to lessen the risk of a major cardiovascular event (such as heart attack or stroke) in people who already have, or are at high risk for heart/blood vessel disease. Dulaglutide is similar to a natural hormone in your body (incretin). It works by causing insulin release in response to high blood sugar (such as after a meal) and by decreasing the amount of sugar your liver makes. Dulaglutide is not a substitute for insulin if you need insulin treatment.

About this data. The prescription history for SIERRA R WALLACE MD is compiled from the Centers for Medicare & Medicaid Services (CMS) Medicare Part D Prescriber Public Use File for calendar year 2023, the most recent federal release. Figures cover prescriptions filled for Medicare Part D beneficiaries only; prescriptions under private insurance, Medicaid, or self-pay plans are not included. Because prescribing decisions are generally consistent across coverage types, this record offers a useful view of the overall Internal Medicine prescribing approach at this Boston, MA practice.

Reading the costs. Drug costs are gross amounts paid to pharmacies under Part D, including both plan and beneficiary payments. They are not the price a patient pays at the pharmacy counter. Medications with fewer than 11 claims are excluded from the federal source data, and state comparisons use the average volume among MA prescribers of the same medication. Always confirm current medications and costs directly with the provider and your plan.
