Question: Hello. I have been prescribed metaprolol for high blood pressure and heart rate. I also have thyroid problems and in addition am tapering myself from Klonapin. As long as I stay within the confines of my taper my HR and BP have always stayed low normal. Made some mistakes over the holidays and went back into withdrawal.. and my BPs plus HR skyrocketed. I am concerned that the beta blocker may drop my heart rate too low, still remains to be seen. What options might I have if the metaprolol drops my HR too low. Thank you May

Hi friend,
Welcome to Health Care Magic

Management of Hypertension is now well advanced.
There are several classes of drugs and several drugs in each class.

You can change to a drug from another class or a different drug in the same class.
Among beta-blockers alone, there are several / some selective – example nebivolol.

Beta-blockers must be tapered / not stopped abruptly – that could result in rebound.
Similarly, sudden reduction of clonazepam (Klonapin) could lead to withdrawal phenomenon.

One can go back again and taper.
Gradual tapering under medical supervision is advised and easy.

Nothing to worry.
You just need patience and perseverance.
Be in constant touch with your doctor – all will be well.

Take care
Wishing speedy recovery
God bless
Good luck

How can I lower my heart rate naturally or with supplements and not beta blockers. my rate runs around 82 beats per minute. i exercise 4-5 times per week but still runs at that rate. been recently diagnosed with benign pvcs but will have echo done as precaution. i feel is my heart rate were lower it wouldn't cause so much excitability in my heart to start the pvcs. blood pressure normal 105 to110 over upper 60 to mid 70s so don't want a beta blocker and have that lowered making me possibly feel tired. any suggestions?

My mum (79) demanded that she come off bisoprolol after taking for 3 years, as she felt she should not have been on it. The doctor agreed and she is now suffering with increased heart rate (120bpm) at times, but wont see a doctor. She suffers generally with her nerves and feels that going back on the bisoprolol again will calm her down. Is she just panicing or will the panic attack be because of coming off the bisoprolol? She also came off bumetanide at the same time, for the same reason (ie she felt she should never have been put on those tablets)
