A coworker has had success on Lomaira (Phentermine). I see that phentermine is on the DNI list, along with naltrexone. My question is, the FAA guidance (https://www.faa.gov/about/office_org/headquarters_offices/avs/offices/aam/ame/guide/pharm/dni_dnf/) seems to suggest ALL weight loss medication is disqualifying. Is that the case? What about Plenity (Oral Superabsorbent Hydrogel)? Is it disqualifying to fly being non-pharmacological?
