Toprol-XL and blood tests

I've booen on 100 mmg of toprol for over ten years. Have all the side effects including tinnitus and impotence. Last week for chest pain spent the night at the er , three blood tests, three ekgs, a stellar stress test and echo. All normal and still the sense of doom and the pain under the breastbone... This has been ruining my life. I'm furious after reading all this testimonies . Olease someone give me advise. ******

I was started on Toprol-XL after a triple bypass in 2000. I had experienced several episodes of rapid heartbeats. For the next 7 years I took it daily and had no side effects that I was aware of other than feeling a little weak if I missed a dose.
During this time, I was diagnosed as a diabetic and started on Lantus insulin. I had some gastric side effects from the Metformin but other than that I was doing ok. I was and am still overweight but I was also in good enough shape to walk 30 minutes everyday on my treadmill and to hold down a stressful job.
In September of 2007 I hosted a large family reunion at my house and had no physical problems. Right after that I came down with a bad sore throat and was put on Clindamycin. At the same time, my husband went to refill my meds and came back with the generic version of my Toprol-XL. Our insurance now requires us to use generics if available. Within two weeks I was having shortness of breath just walking up the steps into my house. I at first thought it was a hang over from the sore throat and went to my GP. He had me switch back to the original Toprol-XL and I felt an almost immediate relief. However, the symptoms did not go away entirely, in fact after seeming better, they came back again. I went back to my GP. He was concerned enough to want to send me to a cardiologist. Since we had just moved here a year ago I had not visited a cardiologist as yet so this doctor was new to me and my symptoms.
So far we have done a nuclear stress test, echocardiogram, EKG's, heart cath, lung scan, and numerous blood tests. Everything looks good according to the cardiologist. And yet, I cannot walk through my house without stopping to try and catch my breath, I have had to quit work since I can no longer climb the stairs to the second floor offices, I cannot sweep a floor without having to sit down.
Is it possible that a side effect from this generic drug could have damaged something permanently? Has anyone else had any kind of problem like this?

Haven't been taking this medication very long started March 1st or so with 50mg once a day. But felt didn't need it so took it kind of sporadically the first week, every other day, then I tried just half the second week 25mg. Then I had to go back to full 50mg this past week, so basically 50 to 25mg for three weeks or so now, and I feel AWFUL. Now that I have dropped back to the 25mg the side effects have lessened but the anxiety is unbearable! My arms and hands go cold and numb. When taking it at 50mg felt very sluggish, cloudy mind, doomed feeling. It just doesn't feel right. I am only 33 years old they did a stress test on me this past Friday and 2-D echocardiogram. Tomorrow they are going to do some blood tests and a get a holter monitor put on me for 48 hours. To see if I "need" to be on this med. I dont' think I do, if it truly was something I needed or helped my body, it would help it not bother more. I truly think I may have some other underlying reason for the high heart rate, my BP has always been normal except when I was hospitalized and then once they had me hydrated and my sugars back to normal (I'm hypoglycemic) my BP went normal I just had the tachycardia off and on. So that's why the doctor in the hospital said to begin the Toprol Xl b/c it's SO SAFE I GIVE IT TO PREGNANT WOMEN!! His words. I pray for those women. After just the one week straight of 50mg when I dropped to 25mg a couple days ago it felt AWFUL to do that as well, today is much better Thank God. But can you have such strong withdrawals after such short period of time? And if so, that is scary in and of itself.

I have had dizziness for 2 1/2 years...when wlaking or sitting. Could it be the beta blockers? How long would I have to be off Toprol to determine if this is causing my severe dizzy condition. I also have arrhthmias...not often but the toprol was given to me for that. It might be effecting my equilibrium. Yes? No? Please answer. No doctor has been able to find the cause of the dizziness. All my blood tests come out just fine...and so do the CAT scans and MRIs. I have seen too many doctors...and lost faith in them. Sorry about that.

I went on Toprol 50mg and feel awful. I could fall asleep at any moment,I have a rash that moves from one place to another every few days, I can't focus on my work & I keep forgetting things. Funny someone mentioned hearing loss I too have experienced that & I am only 42. I did not take it over the summer and was able to loose 30 pounds and the doctor put me back on it and all the things listed above started up again plus I gained all the weight back that I had lost. We are running blood tests to make sure this is the cause but my doctor is changing my medication . Glad to hear I am not the only one having these side effects.

I am a 72 year old male. I had bypass surgery in August 2004. Doctor put me on 25mg of Toprol. About 2 months ago I started having severe hot flashes and cold sweats during the day and night. Have had all types of blood tests - doctor does not know what is causing this. He just put me on antibotics for 3 weeks. I have also been nauseated a lot.
Could Toprol be causing my problems?
