Most prescribed

Pharmacies often give vaccines under a standing order that names one clinician, and CMS counts every such claim under that clinician's NPI. These claims are therefore not a measure of this clinician's own prescribing.

  1. Amlodipine Besylate152 claims
  2. Atorvastatin Calcium150 claims
  3. Abrysvo130 claims
  4. Shingrix127 claims
  5. Lisinopril119 claims
  6. Levothyroxine Sodium112 claims

Source: CMS Medicare Part D Prescribers by Provider and Drug, 2024 (data.cms.gov). Part D covers prescriptions for Medicare patients only; drugs with fewer than 11 claims are not published.
