@Thakera Yes, even on Medicare it was $400+ a month. My Pulmonologist arranged for me to get it with no copay from GSK, GlaxoSmithKline, you can look up their assistance program at https://www.gskforyou.com/ Hope it goes okay for you, I am just in the process fo renewing mine for next year.
Learn how our program can assist you if you need help paying for your GlaxoSmithKline prescription medicines and vaccines, whether you have coverage or not.
