Hello All, I’m 2 weeks on Metoprolol 12.5 ml, should I increase?

Posted , 3 users are following.


I’m new to this community but have posted on Zoloft community as I take 50 ml of Z.  I’m an SVT sufferer and just started Metoprolol 12.5 ml.  My blood pressure is on the low side hence the low dose.  My heart has started almost daily irregularly beating over the last 3 days.  Sometimes its constant for hrs, sometimes I don’t feel it all night.  Could you please give me some advise?  My doc suggested the increase to 25 ml, however, my heart rate is already low and I’m nervous about increaseisng the dose.  Will I feel a big change?

Thank you all, kind regards and clam days,

    I know you're not supposed to use them as-needed, but I've been using a different beta blocker, atenolol, as-needed to try to cope with arrhythmias.  You could try the increase just as-needed.

    There's no magic formula for any of this, just have to try and see what works.

    Hope this does the trick. Even 25mg is a quarter of the normal starting dose so you should be fine. Just fr interest what's your normal BP?  

    (you said it was low)

      Morning Sue,

      My BP is normally around 106/70 and my resting heart rate is in the high 50s, I excersize as there is a lot of obesity in my family.  I actually didn’t increase the dose and the palps pretty much went away yesterday morning, except for a few clusters of fast beats for a few seconds. Should I be concerned about my BP and increasing dose if the palps come back? I’m considering the ablation surgery, Doc appt at the end of the month.  I’m not familiar with your med. What are your palps like and dose the med kick in right away? You only take it when palps hit you? Kind regards for your calm day, - x kat

    I've had two short periods when I had arrhythmia and that's when I was given Bisoprolol. But the Doc said I could take it if and when needed and after a few weeks it never came back. I had only taken a few, and yes they did work pretty well straight away. I still have the original packet which i keep just in case it happens again. My husband has had it too but took no meds and it has never recurred. I'm not qualified to comment on appropriate dosage for various BPs but I would be inclined to take my doctors advice on that. My BP is slightly high and mt resting heart rate in the mid 60s so it would appear you are fitter than me...

    Worrying abut it can make it worse - the mind is powerful. Try deep breathing, tai chi or meditation - they are all calming.

    And don't worry!

      Thanks for the reply. I’m 60 yrs and I’ve struggled with anxiety forever but never took meds, Zoloft gave me my life back as of a few weeks ago. I wrongly thought the palps were anxiety and only just was diagnosed with SVT which the Doc says I’ve also had for decades, these palpitation drugs are new to me too. My sister struggles with SVT too and it appears my Mum has too but she NEVER feels her heart palps. Lucky lady. I love life and don’t want to slow down much so I’m looking forward to ablation surgery soon I hope. Best regards and many thanks. Wishing you and your hubby calm healthy days. -x kat

    Anxiety - tell me about it. I'm 78 and am well acquainted with the beast. I am learning to take control of it through various breathing and relaxation techniques but it takes a lot of practice. I am still discovering tension I never suspected in various muscle groups, particularly stomach and shoulders. Its a leftover from primitive times when under threat you tense up ready to fight or run away but if you just sit still you get the resulting flight chemicals sitting in your blood stream with nowhere to go. So either work it off, concentrate on something interesting funny etc to take your mind off it or just relax muscle by muscle from face to feet. Sounds simple but it really helps. Try yoga,Alexander technique, or chikung, they all help with that. And if you're taking atenolol weatch your legs - it made mine swell.

    Stick with it!
