I think it is a matter of making sure you are stable on any med like that and with drs approval, if dr says no driving & it is in your records, then it means no driving until dr gives the OK.

But usually once they are sure you are doing well-with no cognitive or slow reflex issues, they they will OK it if you feel up to it.
Then from legal standpoint it is the same as with drinking, if you feel impaired at all best not to drive.

This is just what I gather from my reading around all forums here.
