Hi baba,
Carbimazole can cause a severe drop in white blood cells making you susceptible to bacterial infection. A family member had this unfortunate reaction called agranulocytosis; he had to discontinue carbimazole therapy. He was then prescribed propythiouracil which eventually controlled his condition. The down side, he has to remain on a maintenance dosage as his hyperthyroid condition returned as soon as he stopped taking the drug. He is not a pilot so no problem. However I did remember hearing about loss of flying status if one's thyroid had been surgiclly removed. Any one with more info on this?
