There are no legal limits to prescribing much of anything, at least at the federal level. States can and sometimes do put strict, arbitrary limits on
quantity for CII scripts, but that usually means filling them more often, they don
't say anything about how high a dose you can take at a time. For example, in much of New England, there is a cap of 100 "units" for any CII script filled, so the most you could fill at on
e time was 100 tablets, capsules, patches, etc.
