Toprol-XL and lungs

I was on toprol-xl for almost 8 years without many problems. i also take isosorbide mononitrate.A few months back I was switched to the generic version (metoprolol succinate er by sandoz) now i have many problems.First I have to say I am disabled with severe COPD. Although I do not feel depressed I have a lot of symptoms of depression. Remember I had no symptoms what so ever until switched by Walgreen's or HMO or Doctor to the generic version. Not sure what to do I have a doctor that does not truly listen,plus he did not want me on toprol xl to begin with. Even though it was good for me. Good luck people!

I have many of the same reactions to this med that I have read on this site. My sister is on this med and we began comparing symptoms, which were many of those listed here..total energy drain, dizzy, unable to concentrate or even focus, depressed. I feel like I can't get a full breath in my lungs and I find myself sighing a lot, which does get more air into my lungs. It is hard to describe but it is a very bad feeling that I am slightly dizzy, slightly nauseous all the time. No ambition, staying in bed more and more because I just feel bad most of the time.

I stayed on this med for four months trying to see if I would eventually get over these feelings. Didn't happen. This week my Dr. try changing me to Cozaar for my HBP so I am in the process of weaning myself off Metroprolol. I was only taking 25 mg 2Xday so I cut them in half and take twice a day. I can already tell a difference in my energy and general feeling of well being. Dr said after one week of half dose, to stop completely and take only the Cozaar. I hope this works. I appreciate all the input on this topic here.

I had been taking 50MG of Toprol for approx 1 yr with no apparent side effects. A few months ago, I went through a Cox-Maze open heart procedure when my dosage was doubled to 100MG to help reduce my elevated heart rate of 120-140 BPM. My heart rate continued to remain high and I had a very pronounced shortness of breath, went to the ER where I was found to have fluid around my heart/lungs. After being treated with diuretics and a couple additional medications, the heart rate continued to remain high so my dose of Toprol was doubled to 200 MG....since that time, I have noticed increased muscle weakness, fatigue, and have almost passed out several times. It is a very scary and insecure feeling not being able to go anywhere or do anything in fear of passing out.

I take it for Mitral Valve Prolapse

Shortness of breath - It feels like my lungs are too small to take a big breath that I need, especially when yawning.

Lethargy

Difficulty sleeping as sound as I used to before taking 25mg a day.

Higher body temperature, especially while sleeping.
