Some time ago I was prescribed Seroquel and was on and off it for different periods of time (usually a few months to 1/2 year) until I couldn't deal with side effects mainly brain fog, lack of motivation & energy, weight gain and more. It also helped with anxiety as well.

I never knew that Tachycardia - or a rapid heart rate was a side effect, I know I had looked over the side effects but this is one that I never noticed, may not have known what it was - especially if the word Tachycardia was used (which I would suspect many people wouldn't know unless it was explained to them).

Some time after being off the medication, I ended up taking it again and maybe the 3-4th dose (so 2-3 days after stating again) of 150mg, I started feeling extremely anxious, shaky, a little dizzy, elevated temp and noticed my heart was pounding and BPM was high and climbing. I was totally freaked out when I counted the rate (well over 200) and thought about calling EMT/EMS but that caused more anxiety due to past experiences with hospitals and such.

So I decided to lie down, meditate, control my breathing and try to relax as much as possible. I wrote a note saying I took my seroquel dose and decided not to call EMT incase I died, but luckily I didn't need that note. The elevated rate lasted about 30-40 mins at its highest level and I really focused on my breathing and picturing something pleasant.

I just searched "Seroquel rapid heart rate" and found many stories about it, 2 of them on here, and they described almost the exact same thing I went through, and the odd thing is that man of them also were too scared to call EMT - which seems to be an unusual coincidence (possibly b/c many have had similar treatment??)

I think people need to be more aware of this issue because when I was in the hospital a couple times, almost everyone was being given seroquel (which was odd in itself...) and I am wondering if people have died because of this, either directly from the heart rate, or from something like an accident (auto or otherwise) caused by reaction to the hear rate.

Here are just 2 other posts with similar stories. I can't post links (board rules) until 10 posts but you can find them by their post number in the URL, the post numbers are:
