Withdrawal due to discontinuing microdose of metoprolol

Metoprolol can be discontinued quickly, but not usually unless there is something else going on and another medication is introduced to take over some of its function. At least, that has been my personal experience to date. I only ever ceased taking metoprolol once my first ablation had failed and I was in distress. The replacement was amiodarone to regulate my heart rate. I was told to cease metoprolol that very instant. No problems. However, the monograph for metoprolol usually says to not cease taking it abruptly, if I recall. I stopped taking it twice, and both times I took about a week to taper off.

I would let your physician know what happened. It couldn't hurt to experiment with cutting your pills into parts and trying to wean yourself off by reducing dosage by about 25% over a week...at least, in your case. Maybe two weeks just to make your heart notice the reduction less.

Thank you for your advice. Unfortunately as I wrote I poorly imagine how else I can cut the dose given that I already take 12.5 which is a quarter of a 50 mg (lowest dose pill).
Yes, it's a good idea to let my doc know.

Hi I don't know the answer to your question and am suggesting you ask your doctor and not us, but there are 25mg pills. They are very small. Also there are extended release pills (don't think you want to cut those). Good luck with your doctor.

Hey, thank you. You're all right, I should and will ask my doc .
And for the time being I'm back on it.

Hi there! While it is a low dose, I take the same amount. Some of us are just extremely sensitive to beta blockers. I switched from the tartrate to the succinate, metoprolol. Helped IMMENSELY. Also, they come in 25mg (succinate, long acting). Although these are slow release, they are scored and you can break them in half, taking 12.5mg at a time.

I don't have tanking heart rates, like I did on the tartrate. A resting heart rate in the 50s is actually good. 80 to 110 resting is way too high.

Anyway, you may just be sensitive to that med. Some of us are. That's OK. If it's keeping your heart from going over 100 when resting, even at a small dose.... I'd say stay on it. Just get the succinate in 25mg pills and cut them in half.

Hope this helps!

Hi, thanks.
That's the most difficult part. I don't remember my heart rate before getting on Metoprolol since I was a teenager and wasn't so aware. And now it makes it even more difficult to understand if it's a withdrawal or if I really have arrythmia.
