Someone willng to pursue a lawsuit might file a FOIA and pursue in court for non-response. A sketchy approach could be suing pharmacy for ... something ... then find the limits for that company via legal discovery.
Land of the free or not.
As a person with adhd, why would i want to sue my provider? They have nothing to do with why there's been an adderall shortage since october. it seems to me the last thing I want to do is make providers feel averse to treating adhd out of concern for being sued.
This sort of thing is better handled through regulatory and legislative means. Perhaps it's not being handled particularly well at the moment, but the status quo seems preferable to establishing precedent that one can successfully sue a doctor for writing appropriate prescriptions for drugs that are scarce due to supply chain bottlenecks.
