Stopping Carvedilol (Coreg): When will the effects wear off?

I had to go to the er three days into coreg therapy at 3.125 mg twice a day. My heart rate was hovering at 50 and would not go up. It is now 48 hours since my last dose and I am still having this issue. I am not athletic at all and am beginning to worry. How long till my hr goes back to normal?

No he was a PCP and he just shrugged off my concerns saying aww 50 isn't THAT low. I didn't even know my hr was so low till I went to the er. My chest just felt like your limbs do when they fall asleep and I was close to fainting just standing around at a family gathering. I monitor my vitals and my hr is generally like 75 to 80 with a BP of 110/68. It plummeted to 50 with a BP of 90/52. At the er my EKG and blood work were all normal. I was complaining about chest discomfort so he wanted to see if a low dose beta blocker would help haha quite the opposite. I never had apparant cardiac problems until now so I'm wanting to chop it up to the lingering alpha/beta blocking affects of the medicine. If it's not better by tomorrow Im debating going back to the er. I don't want to faint at work tonight but it feels like I'm headed that way. I should have seen a cardiologist.

@incrediblemulk98, I have been taking Coreg (Carvedilol) in much larger doses (25mg twice daily) for many months without incident or worrisome symptoms. It became the drug of choice to treat high blood pressure after I developed atrial fibrillation 18 months ago. My first prescription was 6.25mg twice daily; that was doubled to 12.5mg and again to 25mg after it became clear that the drug (a beta blocker) did not slow my heart rate too much.
In my case, I had a natural slow heart rate of 48-50bpm based on a fairly athletic youth and adulthood. When a-fib started at age 80, my heart rate raised to 70-75 -- still not particularly worrisome. At my current dosage, my heart rate hovers around 65 bpm, which raises no eyebrows either. My medical team includes both a cardiologist and a nephrologist, both of whom endorsed Coreg for use in managing high blood pressure with an irregular heart beat, which I had for years but never saw it show up on an EKG before 2015.
Was your prescribing doctor a specialist? Why was Coreg prescribed for you? What symptoms sent you to the ER? Can you call your doctor today and ask how you should deal with your current symptoms? Don't answer these questions here if you don't feel comfortable doing so, but raise them with family or close friends and especially your medical team as soon as you can -- not because another emergency is in the offing, but because you'll sleep a lot better if you can understand your situation better.
