Percentage of propranolol prescriptions filled with generic?

Very high. Propranolol is an old, off-patent drug, and in the U.S. the vast majority of prescriptions are filled as generic.

- Rough range: about 95–99% of propranolol prescriptions are typically filled with a generic version in recent years.
- Exact figure depends on the dataset (Medicare Part D, IQVIA, national drug utilization reports) and the year.

If you tell me the country and the year (and whether you want tablets only or all forms), I can try to pull a more precise percentage and cite the source.
