I've suffered for anxiety and panic attacks for a while now. I was prescribed propanolol 40mg 3 times a day. However, yesterday I had to come home early from college I felts faint, like my body was going to pack in & no energy at all, on top of this i was having a panic attack. I got a doctors appointment straight away and they've upped my propanolol to 160mg once a day and 50mg sertraline once a day. Just wondering whether anyone has been prescribed these together at those dosages?
