Hx symptoms and conditions

I'm 56 y/o with hx of MVP,SVT and was on Inderal for 23 yrs. until after taking RED BULL energy drink threw me to AFIB that sent me to ER and got admitted overnight ,that problem got resolved until about few months ago i started having on and off palpitations again and my doctor put me on 50mg METOPROLOL and take extra dose for frequent palpitations but i noticed that the more i take METOPROLOL the worst my symptoms gets with some dizziness, sleepless nights ,occasional chest pains,joint pains so i went to my doctor again ,had stress test, 24 hr. monitor, and everything was normal, i was then referred to a Cardiologist-Electrophysiologist who told me i was taking to much Metoprolol that i should cut it to 25mg , He planned to put me on 30 day holter monitor to see the activity of my heart but on the other hand being a nurse i tried to monitor myself, i still have the same symptoms but less since i cut down my dose but i decided to stop the Metoptolol completly and put myself back on Inderal for about a week now i'm telling you it was alike a night and day symptoms of increasing palpitations are less and i feel much better , hopefully i treated myself and goodbye Metoprolol.

I have been taking kelone for 20 yrs due to palpitations and a rapid HR the pappitations got worse over the last few months and I was panicky so I went to the dr and this is what happened!

I was put on metoprolol 25mg 2x's a day and it didn't work. I found myself in the hospital with a rapid HR and not feeling well. I had been on kerlone/betaxolol for more than 20 yrs and my NEW Dr was not familar with it so he swithched me. I went to fill the RX and was told by the PharmD that it had a very short half life compared to my old med. I asked the Dr. he said lets try it. Well like I said I was in the hospital within 2 days. I wanted to know what you all think about switching from generic to Toprol Xl and what should my does be? I was raised to 50mg metoprolol 2x's a day and it still doesn't seem to work. I know it is wearing off and I feel crappy! I am 38 with a hx of type 2 Diabetes which is controlled and I take Metformin 500 mg er. I also take Crestor 20 mg all other things are ok but I can't excercise or do any activity due to the feeling my heart is going to POUND out of my chest.
Any and all advice is welcomed since I am new to this med and dont't know if I go back to the palpitations I had with my old one or feel like crap with the new one.

I am a 66 year old female with mild hypertension successfully treated with 25 mg HCTZ for over 10 years. In January 2008 I developed sinusitis and ended up in the hospital for a week exceedingly high BP and an electrolyte imbalance. Initially the MD wanted to give me Lisinopril, but I told him that there is a hx of family sensitivity to the drug. Both my mother and brother had developed a severe cough and had to stop Lisinopril. He prescribed something else. It's now 2 months since my acute illness and they can't get my BP under control. I told my MD that I would be willing to try Lisinopril since the cough from my sinus infection is now gone. I didn't want to rule out using it just because of a family hx. Maybe I would react differently? I am already on 2 BP meds and Lisinopril made it #3. I took 2.5 mg Lisinopril and for 3 days felt wonderful. My BP was terrific. I suddenly developed severe acid indigestion which kept me awake all night. The next day I had a dry cough which would make me me gag. Then I developed non-stop belching, nonspecific stomach discomfort, and loose stools. I felt "not quite all there". My BP has been terrific. I just called my MD and she will prescribe something else. I asked her, taking only 2.5 mg, if it's possible to develop side effects in only 3 days and she said yes. Wish me luck as I try my new 3rd BP medicine.

I AM A 34 YO FEMALE WITH HX OF SEVERE PANIC ATTACKS, DEPRESSION, MOOD SWINGS, AND CONGESTED HEART FAILURE. I HAVE TRIED APP 20 DIFFERENT MEDICATIONS THE LATTER BEING SEROQUEL 250MG, (down from 1000mg), PAXIL CR 25MG, AND XANAX 8MG PER DAY. I HAVE GAINED APP 125 LBS IN 4 YEARS. MY PSYCHO MD SAYS THAT WITH ALL MY PROBS THIS SHOULD BE THE PERFECT MED. I START ON IT TOMORROW AND I AM SCARED TO DEATH TO TAKE IT. ANY ADVICE ON HOW LONG IT WILL TAKE TO FEEL OR SEE A DIFFERENCE.

After two days of taking Biaxin XL, I feel much better physically; the metallic taste in my mouth is tolerable. A possible side effect that concerns me is I've since been experiencing sleeplessness, increased energy and an incredibly good mood (I like the good mood and energy) but is it facilitating a move into a manic phase? (similar to what Prednisone has been known to do) I'm otherwise a healthy person with no hx of depression or any other mental illness. Anyone else experiencing this?
