Nin Posted December 14, 2021 Report Share Posted December 14, 2021 I'm confused because I forgot to take my beta blockers today but my heart rate is normal (not going up by 30 beats when standing) its not going high as I would have expected it to by not taking the beta blockers. Im confused now thinking I can't have pots and I got control over symptoms. Quote Link to comment Share on other sites More sharing options...
cmep37 Posted December 14, 2021 Report Share Posted December 14, 2021 Are you on other meds for POTS as well as the BBs? If so could they be enough on their own to control your HR? Or maybe there was enough BB still in your system to stop big HR rises - do you take extended release BBs? How did you feel - still POTSy or normal? What about your BP - how was it?

No I don't feel normal still felt rubbish standing etc. My blood pressure was normal. Maybe like you said it may stay in your system.

Nin Posted December 14, 2021 Author Report Share Posted December 14, 2021 Just read that bisoporol can stay in the system for 1-2 days after you stop taking. So it must still be in my system I suppose 🤔 Quote Link to comment Share on other sites More sharing options...
MomtoGiuliana Posted December 14, 2021 Report Share Posted December 14, 2021 I think it can also just depend on how well hydrated you are, time of day, if you've just eaten, and other factors. When I have flare ups I do not continuously have the dramatic change in heart rate that technically defines POTS. But I have disabling symptoms just the same. My doctor says it's "POTS".

MikeO Posted December 14, 2021 Report Share Posted December 14, 2021 @NinDrug half life does come into play. I would know it if i missed my metoprolol and lisinopril my heart would be off to the races. Since i changed meds Carvedilol and Amlodipine if i am slow or mis a dose i am ok. The Amlodipine has a half life of 30 to 50 hrs. Quote Link to comment Share on other sites More sharing options...

MikeO Posted December 14, 2021 Report Share Posted December 14, 2021 @NinThe half-life of a drug is an estimate of the period of time that it takes for the concentration or amount in the body of that drug to be reduced by exactly one half (50%). I have included a link that explains it. https://www.drugs.com/article/drug-half-life.html Quote Link to comment Share on other sites More sharing options...
