- Only prescriptions filled by people with Medicare Part D drug coverage are counted. Private insurance, Medicaid and cash purchases are not.
- CMS leaves out medications with fewer than 11 prescriptions and hides patient counts under 11.

- Medication descriptions are summaries from CMS. They are not medical advice; ask a health care professional about any medication.
