New on Metoprolol 25mg

This is my third morning waking up from metoprolol, 25mg. I'm taking it because my doctor suspects I have long QT. Only measured on tilt table but my 24 hour holter test was normal. My stress test was - heart is "good." No word on whether he saw long QT in those tests. I'm 56 years old.

Anyway I posted before, but this is a different subject: I have shallow breathing at night after I take it. I take it at 8pm. It is hard to sleep. Is that how it's going to be from now on? Does shallow breathing go away?

Propranolol has a reportedly better shortening effect on Long Q than Metoprolol. Are you taking Metoprolol Tartrate?  Metoprolol has a very short half life; typically 5 hours or so.  In that time, half of it is metabolized. Physicians usually prescribe Metoprolol to be taken twice a day beca use of his. MetoprololSuccinate is the time release version, and that is taken once a day.  In addition 25mg. is an exceedingly small dose.  I would think that you should acclimate to it in a couple of weeks.  I'm on 75mg. per day, and I feel no I'll effects whatsoever...

Thanks. I am on a small dose because the cardiologist is not convinced I have long qt syndrome. But long qt was measured during tilt table test and my 24 hour holter test and stress tests did not mention long qt. holster test was normal. I am taking the Metaprolol Succinate. My cardiologist is checking into if my insurance will cover genetic testing. Either way I will gladly pay to get genetic testing for LQTS. My grandfather on my mom's side died in his thirties but she and my dad came from large families and that is the only relative who died young and I think it was a heart issue.

I walked this evening before my dose tonight. I don't feel it kicking in yet but it was a big hit Tuesday night

The Succinate is a slow release that will work taken only once a day.  Convenience come with a price though, so I went with the super cheap Tartrate.  Good luck, and I hope you can get to the bottom of it...

Thanks. I left my medicine in a hot car yesterday. In 100 degree temperatures outdoors. Took a dose last night and did not feel it. My BP shot up to 138 over 93  this morning yet pulse is 62. My pharmacy just exchanged my pills for new ones. The girl their said it is to be safe. No wonder I felt like I could swim today. I will take a dose this evening at my usual time. And sleep in Sunday. I am feeling okay., sort of dizzy but will check my BP again around 4pm. If it is higher than 138 over 93 I will take my dose 4 hours earlier than my usual time.

Not so bad. I did not have my own cuff with me but used the one in the pharmacy. My arm is too big for that cuff. It overestimated my BP.
