Pulmicort Flexhaler is a very good medicine to use to keep from having an asthma attack. I was using Advair disk, which is at least three times as expensive as the Pulmicort Flexhaler is, and then the doctor said to try a Pulmicort sample. After using the Pulmicort inhaler for a while, I think I actually like that better. The problem is that there is not a definite way to keep track of how many puffs you have used. It only goes in 20 incriments and that is hard to keep track of. I usually use th date I got the prescription and then go two months from that date. Why are all the new drugs, like Pulmicort Flexhaler so expensive. The inhaler's that you use for when you have an attack are so much cheaper. I feel it is another way for the drug companies to get rich. I can't believe how much money the CEO of the drug companies get. It seems like when you find something that really helps you feel better, it is so expensive.
