Sorry, I should have made it clear that I was indeed referring to drug therapy.
The AME is well aware of the rules from the CAA, because I took a copy of them with me to my medical.
We spent at least half the medical arguing about it (which put my blood pressure up). He seemed frightened of the airline's response to grounding me for a couple of weeks.
Anyone else had any similar experience? Were you grounded for treatment or not?
