TrulicityDulaglutide12$1,501.52 Less than typical

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).

Dulaglutide is not a substitute for insulin if you need insulin treatment.

About this data. The prescription history for SON QUYEN HAI DINH 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 San Francisco, CA 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 CA prescribers of the same medication. Always confirm current medications and costs directly with the provider and your plan.
