About this data. The prescription history for DR. NITA THAPA MD is compiled from the Centers for Medicare & Medicaid Services (CMS) Medicare Part D Prescriber Public Use File for calendar year 2024, the most recent federal release.

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 among SC prescribers of the same medication and form, shown only when at least five prescribers contribute. Always confirm current medications and costs directly with the provider and your plan.

About the medication summaries. Drug use descriptions come from the CMS Medicare Part D Drug Spending Dashboard (2024), and substance definitions from Medical Subject Headings (MeSH) 2026, U.S. National Library of Medicine. They are summaries that do not contain all possible information about a medication and are not individual medical advice.
