Link between Seroquel and Heart Problems?

My son struggles with schizoid effect disorder. He is currently on 300mg of serequel and takes the invega shot. His heart rate has gone to 140 and is steadily above 100. His doctor has said she wants him to start taking 150mg serequel instead of the 300mg. She said it would be okay to move from the 300 to 150 right away. I am concerned. I know we need to do something I just hope that the tapering from 300 to 150 is drastic???? Any thoughts???

Doctors hand our Seroquel scripts like candy. I said “no” to Seroquel and was denied further treatment from my physchiatrist. He claimed it was “so safe” it’s given to children.🤦🏼‍♀️

Last night I felt as if I was going to die, my heart started beating so fast & I felt as if I was going to faint.. It lasted only about a minute.. I went to the ER and they did the ECG & some blood tests and a chest X-ray and everything looked fine is
What they said and blamed it on anxiety and sent me on my way. I feel like they weren’t trying to help me at all. Anyways I did some research linking Quetiapine to multiple cases of heart failure & just cardiovascular problems. People in their 30’s... I am 26 and have never experienced anything like this. I really am scared to take the med now but I really have no choice.. unless I want to go through severe withdrawals.. I feel like I cheated death last night... but maybe I just prolonged it... it’s Sunday night I’ve tried to talk to multiple medical professionals. I plan to call my PCP tomorrow.. if anyone has been through anything similar or has some knowledge about this kind of stuff that would be awesome.. I could really use some good advice.. Thank you

I understand this may be a little late of a reply.

I know everyone here seems to be talking about tapering off Serequel, but I was on 800mg for about 8 years. When I decided to come off I stopped without tapering. I just threw the pills away and prepared for a crap time.

The withdrawal lasted about 3 days and after 2 weeks I was ready to continue construction work. For a family member. I'm sure it may not be the same for everyone else, but I can only speak to my own experience.

I'm definitely not a medical professional. But the choice was simple for me. Potentially fatal heart problems or a bad withdrawal.

To be honest it was a mild withdrawal in comparison to other drugs iv had to come off.

I am having similar issues. Were you able to wean off? Any luck. I've tried to reduce before but have terrible itching side effects

I have not had any itching side affects. But, I have managed to wean myself from 600MG down to 150MG since my last post. I am finally seeing a light at the end of the tunnel. How much do you take? My recommendation is to cut down by 20-30% every two weeks. Maybe even less (whatever you feel comfortable with). Wean down until your down to 25mg and cut cold turkey. I live in Denver so the legal marijuana has also been helping. What has REALLY helped me which is kind of my own “made up practice/routine” is I will try my hardest to sleep my first four hours without taking it then take it in the middle of the night with an alarm set to remind you. That way when you take it you’ll be able to fall asleep instantly because you are already tired. & that got rid of my paranoia of having another “heart episode”. I am hoping to be completely off this crap in a month from now. I hope you can get off of it too! I know it’s tough but if it’s causing heart problems it must be done. I haven’t had any episodes since.. Some doctors are just sick in the head to be giving it out like candy. In my opinion this should be a scheduled drug for sure. Actually it shouldn’t even be used for sleep in people who don’t really need the med.
