Hi I have been prescribed 80mg of propranolol to treat anxiety daily. I have been debating whether or not to take it. I have been suffering from extreme anxiety especially when I try to go to sleep. I feel scared and feel like I cannot breath or that I am going to have a heart attack or something. I am 39 years old and a smoker. I am currently taking fluoxetine 40mg, esomeprazole 30mg and levothyroxine 125mcgs. I generally have quite a slow heart rate and my blood pressure can be on the low side. Do you think propranolol will be safe to use and effective in the treatment of my symptoms? Thanks
