Question: I am nervous about taking my first dose of metoprolol (12.5mg). I have had constant PACs for three weeks now and this is what the doctor (GP) recommends I try. I am also on lisinopril-hctz (10-12.5mg) for two years now for blood pressure. Should I be this worried about any side effects taking this drug tonight (with a snack before bed)? Also, I will be seeing a cardiologist on Tuesday. Should I wait to take this until I see him?

Thanks for query.

In general, 25mg of metoprolol is safe drug. Unless your BP (Blood Pressure) or pulse is low there is no concern and you can go ahead and take it as it is good drug to suppress PACs but if your pulse or BP is low and your are not unusually symptomatic you can wait you can wait till you see cardiologist.

About beta-blockers (Metoprolol), side effects they can cause:

1. Low hear beat
2. Low BP
3. Electrical disturbance in heart
4. Some modest effect on lipids
5. Bronchospam or wheeze

Do write back for follow up queries that you may have.

Thank you for your reply. I have taken tonight's dose of 12.5mg and so far all is good. How long before I might feel relief? Does it work right away or does it take time? Thank you.

Generally, it takes about a day or two to have relief though action would be immediate. It takes about two days to bring about enough reduction in number of APCs. If you are fine, keep taking.

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)
