Is there a list online or anywhere of unapproved meds by the CG??
Get the NVIC 04-08, enclosure 6. It’s not a “complete” list, but it’ll get you started.
Watch out for the over the counter stuff too. A friend of mine wrote down that he takes cold medicine (sudafed, zyrtec, and the like) for seasonal allergies. They didn’t ask him for amplifying information…no, they restricted his license so that it was not valid if he was using the cold medicine.
