Yeah but let's be real, while the "specific approved use" might be clear to a medical practitioner in a journal write-up related to FDA approval, the actual prescription ads shown to normal people attempt to use as general simple wording as possible to describe symptoms. To laypeople these start to blur together to very simple statements like "feeling tired? Worried about excessive weight gain?" While these might be symptoms of a specific FDA approved use of the drug, it results in an atmosphere of confusion for normal folks.
