    My father has been on Metoprolol medication 25mg 2x daily to control heart rhythm since 2004, after having a heart attack caused by the drug Avandia,he has 4 heart stents one is doubled. Since 2006 he has been suffering from shortness of breath,fatal wheezing choking so bad with phlegm we have called 911 a number of times because he could not catch his breath. Very scary. He also has 11 of the 14 common adverse reactions they are, dizziness and lightheadedness, extreme tiredness, he has been telling me for quite some time now that he is ready for the bone yard. He gets depressed, feels nauseated, dry mouth, stomach pain, gas and bloating, heartburn, rashes like hives, itching so bad he scratches and either bruises or starts bleeding, has very cold feet at all times wakes him up throughout the night, and has the worse constant runny nose I have ever seen, when he sits up his nose is in constant flow. Just found out that this drug was a black box warning, can’t wait to tell him..

    When I started taking Metopolol I was 43 and weighed 140 pounds, went through several health issues, which were resolved, blamed the health issues for my depression, fatigue, etc. Weighed 250 after 2 years. I recently slowly with Dr.s okay reduced my dosage while starting another BP med. I am back down to 160 and dumping weight with no effort.

      I’ve had similar side effects. Experienced more weight gain over the course of a year and a half, and I’m 26 years old

      You need to insist they take you off of Metoprolol, I have been taking it for a few weeks, it is causing me not to be able to breath,

      • K.Freeman

        I am completely off this drug at this point. Thank you.


    I was put on this drug with no problems (?) when in the hospital after a heart attack. I do remember the nursses giving me Xanax for sleep but besides the beds being uncomfortable I din’t remember ever getting a good nights sleep. once released, I went home and kept taking the medication. i missed a dose and noticed my fast heart rate. I looked up the drug and noticed to be a side effect. So i couldn’t figure out why a drug that was suppose to help my heart could actually kill me so i weaned my self off. After the first doctor decided i wasn’t going to be his patient 9would have been easier to try another drug) I found another doctor and he is trying me on a lower dose. first day on the drug and I was winded and dizzy. I have since developed a phobia driving. I complain about the side effects and all the nurse says is “drink more water”. I am so happy that so many people tollerate the drug and I give them all a golf clap. Unfortunately i hate this drug and if the doctor doesn’t do his job and give me a different one. then goodbye. sorry i had a heart Actack … see you when i have my next one.

      This is not a good drug for me, I have been on it a few weeks and can’t breath . I missed one dose and was ready to go to the hospital because I could not breath!! It felt like my lungs were not working. I intend to get off of this medicine as soon as possible. Feel dizzy, tired, can’t breath, not a good med!!

    • Kim

      It gave me a driving phobia too, along with several other complications which I never had until I took that poison.

      • Mike Smith

        Kim, i use this medicine and my driving isn’t affected in any way.

  • s dubbya

    I have gained over 100 pounds while on metoprolol. I am taking 300 mg/day and the doctors don’t want to take me off of it.

    I am literally miserable and hate being this weight, especially after I had lost 100 pounds with my own hard work in the gym and dieting before starting metoprolol. It made me gain back every pound!!

  • pawanna

    Not a good drug for me – my Doctor RX was for Toprol xl – i did ok on that drug…. then my insurance company switched me to Metoprolol – then i started feeling bad and thought it was me – i told my Doctor about being short of breath – wheezing at times – swelling of feet and ankles……….she didn’t do anything – i kept taking this medicine and felt worse – not sleeping – more bad side effects…… so i finally got smart and thought maybe it is this crappy medicine – read about all the problems and talked to my Pharmacist….. no more generic for me…. i feel better already…….. to think this stinkin medicine was the cause of my not feeling well for 8 months is UNACCEPTABLE

      For me it was 10 years.

  • Dea

    I’ve been taking this drup for 5+ years and have had no side effects. After reading these comments though, I am worried.

    • Bill

      I’m on Metoprolol ER 100mg/day and doing just fine. With triple bypass, followed by 3 stents and 2.5 hours of ballon angioplasty just 3 months after, I’ve been riding my bike at 7-10 METS for 7 miles/day ever since. If it weren’t for the Metoprolol, doubt I’d even be alive today.

  • John Waaser

    I was put on metoprolol following a single episode of atrial fibrilation. Encountered several problems including gained back 25 of the 40 lbs I lost a couple of years ago. I suffered from increase in peripheral neuropathy I had been complain I ng about on my record, plus joint pain and sleep problems, shortness of breath and swelling noticed by doctors at the VA medical center. Most srious from my standpoint was a total loss of sexual function, which continues to this day, in spite of weaning myself off metoprolol. My doctor switched me to atenolol at one fourth the dosage. Peripheral neuropathy seems to be improving slowly, but weight is still climbing, even after dropping the evil medication.

  • InVinoVeritas

    I was on this garbage drug for a decade to lower my pulse. I have not one good thing to say about it. Doctors are just $|-|!t.
    Beta blockers in general are just miserable, lousy drugs, and this one is the worst.

    • Mike Smith

      It is strange InVinoVeritas I was given this drug because my paulse was down to 40 bpm but my systolic and diastolic pressure was normal. Why would a stupid doctor gave me something to lower my blood pressure when it was low before I took it ?
