A worthy addition however is this view about reducing anxiety and aggression, which is something I knew of

This is what my original cardio used to stress on saying about the benefit of staying on it in addition to lessening the work load on the heart.
After what I had gone through after I stopped it twice, now I love my metoprolol (personal opinion)!
 
Avid, 70 year old, recreational road cyclist here 13 weeks post-AVR with a 25mm Edwards Inspiris Resilia. I was put on Metoprolol Tartrate (25mg morning, 25 mg evening) for some sporadic post op aFib and after wearing a monitor and having a few more short term episodes, my cardiologist wants me to stay on it for the time being. I have not had any side effects but my main concern was impact on endurance exercise with the lower heart rate. After being released to ride outdoors last week, I have several observations. First, in replicating a ride I had done pre-surgery my average and max heart rates were about 15 to 20 beats lower but my average speed, and my subjective view of level of effort, fatigue, etc. we’re almost identical to how I felt on the same ride pre-surgery. Second, I’ve wondered whether my higher pre-surgery heart rate was my heart’s adaptation to my exercise load demand being pushed through a stenotic valve and that now, even with a lower heart rate, the stroke volume with each beat is increased because of the unrestricted flow through the valve so the pre and post operation efforts feel the same. Regardless, I’ve done three rides since last week and I’m thrilled to say that I don’t feel the Metoprolol is impacting performance or sensations on the bike. Of course, I’m not a competitive athlete so perhaps I don’t notice the decline the way they would…..

just wondering, are you on Tartrate or Succinate?

The difference is that on Tartrate (because of its shorter half life) you can time your exersize around taking it.

Hi



its possible that this is just a coincidence. I can't find reports of it and my similar experiences were not on it but I attribute to being on the stuff they give you after General Anaesthetic.

I also found trauma is related to these things (in me at least, as well as some veterans I know)

I had no idea it could be causing nightmares until I stumbled upon multiple folks complaining of that side effect. One of them was (IIRC) posted by the wife of someone on it who said something like her husband was forced to sleep in a different bedroom because he would be thrashing around/yelling/screaming/whatever while he was on it.

I can't remember where I read those posts but if I get time at some point I'll post a link...

I had very vivid dreams when I started taking it (and could have written books), which subsided with time. But never nightmares.

That reminds me, I am on a PPI (prevacid). Been so for years (way longer than anyone should be on these things but have no choice supposedly because of horrendously bad acid reflux disease due to a floating hiatal hernia causing a weak lower esophogeal sphincter (LES)).

One of the known side effects of PPIs is very vivid dreams. I noticed this right away on the first PPI I was on (aciphex, which after about 2 years stopped working & then got put on prevacid). Those dreams were (are) amazing and usually fun. Also just as part of my normal brain for some reason I've always had pretty cool dreams, some I used to write down when I woke up b4 they faded. On a PPI I wish I had one of those brain scanner things from the movie Brainstorm though because they were so realistic yet bizarre/impossible (for example a few days ago I had a dream that my Mom - who passed away long ago - was still "alive" and her essence was living in this metal box thing where she could talk to us)..

Never had any nightmares like the ones on metoprolol b4 though (super vivid and realistic, dreams within dreams) and wonder if the PPI - and my normal way of dreaming in the first place - had something to do with it, pushed over the edge by metoprolol.

Anyways, trying to find the forum/posts now where I read about others complaining of nightmares I found this which perhaps touches on some of this:

The comments I referred to about nightmares may have come from one of these sites:

https://www.drugs.com/comments/metoprolol/https://reviews.everydayhealth.com/drugs/metoprololhttps://www.webmd.com/drugs/drugreview-8814-metoprolol-succinate-oral
I haven't found the specific one about the woman talking about her husband but there are some comments mentioning nightmares. It was about 5 years ago that I read it so I would have to go back to that sort of timeframe in the sites above.

Also reading some of the comments above now it reminds me that I also experienced lack of sexual drive/performance (common with beta blockers I believe) plus even had some really weird blurred vision that people mention. On the plus side something beneficial that happened was that for around 4-5 months - even though only on the metoprolol for less than a month - I had no migraines at all - unlike my usual 5 or so a month that I've had ever since my open heart surgery (although right after the surgery I had more than one migraine a day, which slowly tailed off after like 3 months to become about 5 per month).

As I think I already said though the worst with metoprolol for me was the utter lack of energy, making it impossible for me to do almost anything but sleep/lie in bed, and the problems with thinking/concentrating/getting lost trying to drive to the Dr etc, which did not go away until I was told to cut the pills in half (but even on 1/2 dose I still had some probs).

I'll keep looking for the nightmare posts when/if I get more time.
 
Hello,
Just wanted to share my experience with metrópolol succinate after my surgery (Nov 21, 2022).
It has been around almost 4 months after my surgery and I have been taking a pretty high dose 100mg in the morning and 50 mg in the night before going to sleep i haven't noticed any consistent side effects (meaning always having them) but sometimes I do feel sluggish and it's hard to exercise but not always.
It hard to attribute this to the metrópolol or just being lazy, also i was not in the best physical shape before surgery (as my heart valve was in a bad state). My hr has never passed 150 while doing heavy exercise and it has been as low as 45.

I would love for my Dr to lower my dose or even remove it completely to see if I notice a difference.

I remember that member and others too complaining about nightmares!

I’m sure it happens. And maybe I did have a couple of nightmares after the surgery, but I thought then they were caused by the mix of the many medicines I was given.
But in my case and luckily, It’s been vivid colorful long dreams…some of them were weird, but delightful!😀

My energy level was affected and that’s why I stopped it twice. But, won’t anymore and surprisingly my energy is picking up again!

Good luck.
 
I was put on metprolo for 30 days, for afib after my OHS. I also had severe side effects plus the terrible nightmares. Two years later with random SVT & racing heart rates, my doctor wanted me to start back on it. I told him I refuse to take it. He explained the benefits but I still refused. He then agreed with me and said he wouldn't take it either. (LOL protocol! and showed me I do have a voice in my care!) I met with rhythm cardiologist specialist for an ablation. First, he had me ware a monitor for 30 days and thankfully, my heart went back into rhythm on it's own. So after having multiple episodes for 3 months, they stopped! Yay! God took care of them! I haven't had one in 5 months now! There's no way will I go on metprolo! My number one reason are the dreams! The back-up reasons are everything else. It might help others but not me.

I was also put on the tartrate post-op without explanation or warning - something like 25 mg 2x/day, which was way too much - I had this same experience:

All I knew was that within 10-15 minutes of taking those 2 pills I felt my body (& brain) had been dragged down by 15 ton weights. Like I was on a planet with 100x the gravity of earth. I had no strength. I was overexhausted in ways I thought not possible. All I could do was to crawl back into bed.

Ended up finding that 12.5 mg once a day was better; then went down to just a quarter pill a day for months, so 6.25 mg.... And I had to slowly wean myself off even that, taking an eighth of a pill, a tiny crumb of a pill, so I wouldn’t have arrhythmias and 120 heart rate like I did coming off higher doses. Then I felt weird for weeks after - it was still in my body...

I sometimes miss the calm, “Anything can happen and I don’t care” feeling I got from it, but really I’m glad that’s all over with now.
