 [ Symptoms ] having trouble with blood and iron levels had to have 2 transfusions and 3 infusions [ Disease ] this is another great question and i can tell you that nine times out of ten when i have patients who come to me with this question it is because they are spraying it in their mouth and not inhaling it the way that they are supposed to i actually offer to retrain them on how they are using their inhaler if they do it the right way they should really not have any bad taste in their mouth but they can rinse their mouth afterwards which is absolutely fine
