I get migraines, and tension headaches daily. I am switching from a beta blocker to an antidepressant. My doctor neglected to inform me about whether or not the drugs interact to guess its probably fine but I want to make sure.

Currently, I take 50mg metoprolol which I will starting weaning off tomorrow. For a week ill take 25mg and then stop completely. I was prescribed to take 10mg amitriptyline for one week and then 20mg the next week and 30mg the third week.

Do I need to wait until I am completely off the beta blocker before starting the amitriptyline? Do I need to even wean myself off such a low does in the first place?

Thanks!
