Metoprolol

[Dodgerguy]

hello everyone. I need advice

I am a 50 YO male who takes Metoprolol XL For AFib. I was diagnosed in July of last year. I was on 100 mg Metoprolol XL twice daily. My heart rate was too low according to my Primary Care Doctor. I called my Cardiologist and let him know. They lowered my dosage to 50 mg XL twice daily. Which worked. I put my 100 mg XL tabs away in my drawer where I store my medication. When going to fill my pill counter I accidentally grabbed my 100 mg XL tablets instead of the 50 mg XL tablets. I am not too sure how long I had been taking the wrong dosage. I discovered this mistake last night. I don’t think I was taking the 100 mg XL for too long but not 100% sure how long. I’m going to switch back to my 50 mg XL tabs this morning ( I’m in the U.S.). I had some side effects but did not link it to the Metoprolol till I realized I was taking my old prescription. Can switching back to my 50 mg XL pills have any consequences if I had been taking the 100 mg XL for longer than I thought? Thank you in advance for any feedback!

Just an idea - why don't you cut your Metoprolol 100mg in half and use them up, then this overdosing will never happen again.

Good idea. I took a marker and put a 100 mg on the top of the cap of the bottle. Thank you for the reply

Not a doctor, but don't think it will. I sometimes take 100mg Metropolol instead of 75mg if HR is not stable with no side effects. But I normally only increase for 2-3 days.

The key is your heart rate being within range and no side effects.

Hi

But he is taking 200mg a day!

I thought tops would be 100mg in one day.

Doubling my 49mg reacted as having trouble breathing.

I would think 200mg Metopolol an overdose!

! year 5 months on it 23.75 x 3 daily made me breathless and the monitor showed pauses at night. H/R day 186 avge little exertion as couldn't. Change to Bisoprolol still no control at 156 bpm Day.

At 2 years 3 mths Dr sent me to Private H/Specialist. My H.Rate Day fell to 51! on 180mg Diltiazem.

Quickly reduced to 120mg and reduction of Bisoprolol to 2.5mg separated 12 hours. Now no bisoprolol , but 120mg Diltiazem for 3 years controlled H/R .

The hosptak should have trialled me on both a BB and then alternatively an CCB. I didn't get an ECHO until 1 year 5 months. Just CT Heart Scan.

I would have thought Metopolol of about 100mg is tops.

I almost got rushed to hospital with the 100mg.

No, in the U.S. 400 mg a day is tops. My cardiologist when coming out of my first AFib put me on 100 mg twice a day. That seemed to be too much after about two months due to low heart rate and was dropped to 50 mg twice a day. I did fine physically with 200 mg a day but my heart rate was too low.

I take about 10mg twice a day and when I go into AF I up it to 25mg for a month then back to 10mg no reaction. Back in 2022 they started me on 50mg which made me really tired so after a few weeks dropped it to 12mg gradually(over a few days) and no adverse reaction

Ask your GP as these are prescription only medicines. I wouldn't have thought you would notice at all except that your HR will increase somewhat. I have ranged with bisoprolol between 2.5mg and 1.25mg with no difference noted except HR reduction.

Thank you for your response. I’m back on my regular 50 mg twice a day. I called my Cardiologist and his medical assistant was supposed to to call me back yesterday but didn’t, typical of medical in the U.S., specifically Las Vegas , NV! My heart rate did increase as you stated but nothing too high. At work I ranged from 70’s to 113. I do walk around all day at work up and down three floors ( moving stairs to each floor). Non stop. Once I was off and at home it was still increased by not out of control (60’s-79’s, with the occasional 90’s). Thank you again for your time.

I was only taking half of a 25mg pill each day, and it was pure hell for me. I was finally told to stop taking it, and have had no problems since! Everyone has their own experience though, so mine should not be for everyone.

The best thing to do is call your cardiologist at once and explain to your Dr. what you just told us.

[Dodgerguy]

thank you for your reply! I did call the next morning and was told to resume the 50 mg twice a day and to call if I had any issues. So far everything has been ok, thankfully!!
