Hello, I am knocking on the door of 70 years old in 2 weeks and have had severe asthma since birth. I have also been taking allergy shots since I was 2 years old, minus about 4 years off to college. I can't live without them. They help my life be more normal. I have struggled most of my life with asthma because the meds were so bad back in the 50's and inhalers did not exist. I believe it was in 1994 that Flovent HFA inhalers became available, and it literally turned my entire life around. After a couple of months, my asthma slowly disappeared, and it stays in control most of the year. If I get the flu, RSV, or even a cold/sinus problems during the spring, I might have a flare-up, but it quickly comes under control again with Claritin D and over-the-counter meds. Unfortunately, our government made some changes to Medicaid, I think in 2022, and the British manufacturer stopped producing Flovent in the United States. I have to get a doctor's prescription faxed to Canada, although I order it from Canada. It is shipped from Guy's Pharmacy in New Zealand. I trust New Zealand but not other countries. It takes about a month to receive it, so I can't get low on my drugs. And it has gotten lost in customs once, and I was down to just 2 days before they found it and delivered. So that is a drawback on this drug. And they call it something a little different, and the dosage is a little different, but I order on the site as Flovent 240 mg. Canada measures their inhalers a little differently than ours - I think ours measures drug dosage from the mouthpiece, and Canada measures from another point, making the measurement 250 instead of 240 mg. My Dr has no problem with me continuing to use Flovent. Matter of fact, he said, "Why change it if it is still working?" I do have to pay about a 100 dollars more for a 3-month supply, but I can't find another drug to replace it either. Even the generic Flovent did not work as well on me as the brand. It is the fillers that I am super sensitive to. The pharmacy will lead you to believe otherwise, but all the docs agree that there is a difference in fillers used in each drug and how each of our bodies metabolizes them. That is why they can use generic drugs, the fillers are all different from one name drug to another, but still use the main ingredient. I also have an old inhaler drug called Ventolin (blue one) that the insurance will no longer pay for, but it still works on me better than the generic rescue inhalers. Hope that this helps. Be well . . .
