Toprol-XL and antibiotics

I started taking Toprol XL after being diagnosed with SVT back in May of 2003. I was only in my late 20's & was very trusting, at the time. I was recently sent to a cardiologist because I was having horrible chest pain & the Toprol XL 50 MG wasn't working at keeping the heart rate down. The GP put me on a double dose as well as Cardizem to help with the chest pain & rapid heart rate. I was already on Lanoxin 0.5MG, the highest dose allowed. The cardiologist took me off of the Cardizem right away because he said that is was too stressful for the heart to be on that much heart medicine. I went though several tests & was told by the cardiologist that I didn't have SVT & that this was actually Postural Tachycardia (POTS) & Neurocardiogenic Syncope. I was taken off of Lanoxin, but kept on Toprol XL 100 MG. He put me on lots of salt & water to increase my blood volume which would help my blood pressure when standing. That was in June of 2007. All went pretty good, I thought, until January 18, 2008 when I was working. My heart rate went up to 136 just standing or walking across a room. I called the doctor & talked to a nurse who suggested that I take another 1/2 of a Toprol. I did that & felt better for awhile, but it was short lived. I had been having chest pain, rapid heart rate, fatigue, muscle pain, joint pain, headaches, nausea, vomiting, short term memory problems, rapid weight gain, hair loss, cold extremities, & other things I can't think of right now for what seemed like forever. My gynecologist & my cardiologist first thought that I had thyroid problems, but all tests have come back negative. They then thought that maybe it was from the birth control pills that I had been on for the ovarian cysts. I was changed from one medicine to another & at first I thought that was what was wrong. I am now certain that all of the problems that I have been having were & are a result of the Toprol XL. I was even told that all the problems were "psychiatric in nature". I know that that isn't it at all! I have never had anxiety problems & the GP now thinks that's all that is wrong with me & wants me to go on Zoloft. I tried it, but became so ill that after one pill, I quit. I now plan on weaning myself off of the Toprol XL without the GP's knowledge or consent. The cardiologist was planning on weaning me off at some time in the future, but I am starting without him knowing it at the time. I'll just tell him when I see him next month. Thanks everyone for alerting me to the facts about this medicine. If I had known then what I do now, I'd have never consented to starting it in the first place. My only question is, are some of the "side effects" going to be a permanent thing for me or will they eventually go away? Any advice would be welcome! Thanks again!

I am a 41 yo woman in good health. I started Toprol xl about 3 years ago for a heart palp that would happen maybe once a day, and occasional racing heart beat. I did great for a long time on 25mg once a day. Then about 6 months back I was switched to generic due to insurance issues - they only want to pay for generic.

It took me a while to figure out what was happening, but several problems started happening over the last few months that I am sure were from this generic drug. Suddenly I was having vivid dreams - fish swimming on the ceiling, cats with heads 5x too big! Worse yet, over about 3 months I gained 20 pounds with no difference in diet. And I was getting more and more tired. I started looking into what could be causing these crazy effects - I was only on Toprol and birth control pills.... well, it was not the birth control!

So, I decided to wean myself from the Toprol. I decided I prefer a heart palp and occasional racing heart to this!! I gave myself a couple of weeks of lesser doses, then 5 days ago I stopped it altogether. I am having some horrid "rebound" or withdrawal effects! Numb/tingling hands and feet, headache and - surprise! High blood pressure! I never, ever took this med for HBP, and I have never had HBP! I always had a nice, low blood pressure, even when 9 months pregnant! Now it's running around 135/93 - I work in a medical office, so I got one of the nurses to check it on Tuesday...she sort of freaked! She said she has seen much higher, but mine is not normal. So we have been checking daily, and it's staying up there. I am so mad to think Toprol could have damaged my body in some way so that my blood pressure may not stay messed up for life. I have read online that the rebound effects can last up to a month, even with a fairly low dose like I was taking. Does anyone know if a month is about right? If my blood pressure keeps this high, I suppose I will have to seek treatment at some point. Ugh!

On the plus side, I don't feel so tired. No vivid dreams since I stopped the Toprol, and much better sleep! I feel "clearer" mentally. I just wish the tingling hands and feet would stop - and the high blood pressure!
