Hello all. I’m new here. I have been dealing with migraines for the past 19 years. I was able to deal with them by taking Excedrin Migraine. Back in January-February, I went through a 3 week time period where I had a migraine every day. I decided to follow up with my doctor and see what was going on. She prescribed the beta blocker proponolol. It took a bit of adjusting doses, but once I got to 40mg twice a day my migraines got so much better. Was getting them rarely and they were pretty mild. About a week ago they came back. And early this morning I had a severe one. Has anyone had issues with the beta blockers losing their effectiveness? Can they just stop working like this? I do plan to follow up again with my doctor. Appreciate any input. Thanks!
