risperidone qt

Risperidone is on the list of drugs to be avoided if you already have a prolonged QT interval, however, it is not known to prolong QT interval if you do not have this condition. Some typical antipsychotics (for example chlorprothixene/Truxal) require an EKG before treatment, but risperidone does not. I should add; unfortunately there are other causes of sudden arrhythmic cardiac death which do not involve the QT interval (for example Brugada syndrome).

my son has been on many meds for yrs and had a eck done and showed rbbb and prolonged QT secondary to QRS adnormality, he is bipolar and 10 yrs of age, on many meds since age 1yr.

My question is on tapering risperidone how long does one need to taper risperidone from a dose of 1mg to 0.5mg in days or weeks?.

i am afrraid this is not the risperidone, but it's called spastic colon (Irritable Bowel Syndrome). it just happened that they occurred by chance simultaneously. when you have anxiety you get spastic colon and especially with the change of weather, i.e. seasonal change from summer to fall say. I know it's devastating. They reckon it afflicts up to 20% of the world's population.

my son, 9 , was taking risperidone 1mg BID. he has missed his doses for 2 days and now came home from summercamp with signs of tardive dyskinesia. Is this because of stopping the risperidone or has the risperidone been masking the tardive dyskinesia ?

How do you manage withstand side effects of both Risperidone and Seroquel.I found even 1mg of Risperidone made me edgy,nervous and anxious.My hypomanic episode resolved in July and my Pdoc was a month late in tapering Risperidone.He started tapering process in September.In future I shall keep far away from these antipsychotics as possible.A most distasteful experience.

wow , that's some medication , over the last 10 years i've been on quiet a lot too but for the first 5 year's or so it was mainly anti-depressants and the odd anti psychotic , but they had no odea what they were treating back then, it's only been the last few years i got diagnosed properly ,but they are still not 100% sure about the Bi polar / with psychotic features or Schizoaffective , which is what they call it for now , i don't think there's a whole lot of difference

I am really happy today.Yesterday I took my last dose of Risperidone which I had been taking since the past four months and which had been tapered off by my Pdoc .I never liked this med which had numerous side effects of which I experienced some,thankfully not the worst ones.I will now only have to take my mood stabilizer which I have been taking for a number of years.

She also gets up at night and looks for things or wanders around. The consultant has prescribed risperidone, although we were hoping for Aricept. I am very concerned about this as internet research suggests it is for aggressive behaviour and will result in oversedation even drooling. I don't want my mum to be a zombie - I'd just like her to be more like her old self. Does anyone have any experience of this drug at all? I'm not going to give it to her until I learn more.

I am in full blown withdrawal symptoms from stopping risperidone with anxiety and my psychiatrist is back 5 days later.I had to stop because of side effects at 1 mg.What should I do?

Hi ive been taking risperidone for 3 weeks now for social anxiety it seems to be working a little but in extreamly nervous now sence i been taking it is the medecine suppose to make me nervous im on 1 mg are u going through this please let me know.

Risperidone is generic for Risperidal and I think it's a pretty good option for depression & psychosis. Not so much for anxiety though. It should give you a boost or make you feel energized rather than lethargic due to the increased norepinephrine plasma levels. This does not make you gain weight either. See how it goes and maybe you will be able to eliminate your antidepressant or at least decrease it.

Hi there. Risperidone is an atypical antipsychotic drug with certain side effects. These are sedation, dysphoria, insomnia, sexual dysfunction, muscle stiffness, muscle pain, constipation, photosensitivity and alopecia. The fall could also lead to local tissue spasm and tightness in the surrounding muscles. She needs to be seen by an orthopaedician to rule out this as an effect of injury ad also check for an missed fractures.

My daughter just started taking risperidone 2 days ago and is experiencing the trouble swallowing side effect and not opening her mouth very wide when she talks and having trouble speaking. Is this normal? Will it wear off? Its really scaring me.

Hi - I have some questions about long QT syndrome. I've recently had 3 EKGs because of palpitations and a fast heartbeat. I've asked the doctor who did them about long QT and each time he said there was nothing showing I had it. My QT/QTc was 350/418 on the first one I believe, on the second 362/425 and on the third 358/440. Heartbeat was 86, 83 and 91 respectively. The last one is the one that got me worried, because apparently 440 is the limit for normal.

Sounds like a horrible diet, which could cause a lot of problems, including low potassium (and long QT), anxiety, low magnesium (and long QT), vitamin defiency, etc. You need at least 3000 mg of potassium daily, and preferrably 3.500-4.700 mg (guidelines vary between countries, in Norway it's 3.700). I think your prolonged corrected QT interval was caused by 1) Mathematical overestimation from the Bazett formula due to a high heart rate, and 2) Low potassium.

I am in full blown withdrawal from risperidone and my psychiatrist is out of town.I got side effects(involuntary movements) so had to quit.My doc will be back 4 days from now.Any suggestions.

My Pdoc had suggested an extremely slow tapering of risperidone over 10-12 weeks but I tapered it over 6 weeks and only had minimal withdrawl symptoms.I am yet to go and see him.I am stable on tegretol 1000 mg with no side effects.Hope it stays good.

Thanks for your reply. If it changes anything, I have also found an earlier EKG with a ventricular rate of 96 and QT (uncorrected) 326. Shouldn't my uncorrected QT be lower, or does it stop decreasing with increased heart rate like this? Sorry for disturbing you with such questions, but my anxiety sometimes gets the best out of me...

Yes, a well known side effect of the majority of SSRI''s is that they can prolong the QT interval. This does not mean that they will and "prolonging" the QT interval is not the same thing as having a "prolonged QT interval".

m not a physician) is that Zoloft may prolong QT interval. I think uncorrected QT of 448 msec is slightly long at heart rate 71. I would recommend that you ask a cardiologist and preferrably bring the EKG. Do not stop taking Zoloft without talking to your doctor.

Hi,I have a history of pvc and pac i take atenolol 50 mg a day for this,no high blood pressure ,,i have had many ecg and a few holters and an echo,,and an av node signal average test,,no one has ever mentioned a long qt interval before -i am haveing gall bladder surgery soon and as a precaution they sent me to internist who ordered this last holter,saw clinic doc today for results he said it showed a long qt interval and he did and ecg then and there- no long qt on that one -i was haveing an an

My four year old grandchild/fosterchild has been to the doctor and now take meds for ADHD. Frist was riddelen that did not work at all. New medication is Risperidone. No change has been noticed. This child before meds was pooping and peeing on her bedroom floor and even after meds. Im at my end and dont understand this kind of behavior.

ive been on risperidone for i month now in im feeling sad today i hope i get better in i was just wondering if your on risperidone in do you have up in down days cause thats how i feel one minute im ok the next im depressed.

I would also check your EKG to see what the QRS duration is -- often when people have mobitz type I, the QRS is also widened, which would “stretch out” the QT interval -- a prolonged QT in this setting would not be considered a true QT prolongation.

The psychiatrist has now put Glen (16) ASD on prozac (20ml liquid) once a day alongside his 1mg twice a day risperidone (was on 2mg twice daily but had to cut it down due to Glen becoming constipated). Glen's anxiety is still sky high on the risperidone, been on it nearly 8 weeks so she thought she would try prozac as well. Do you think the prozac will help my son?

She has been on risperidone for many years. Recently we have tried other drugs and her symptoms of aggression have increased. She is currently on Strattera, serequel, and hydroxizine (to help her sleep). She has only been on the serequel 2 days and it is not helping. The risperidone was stopped immediately because of weight gain. I need some suggestions on what we can do. HELP!

my daughter had 2 ekgs and showed a QT interval of 468 with a heart rate of 68. Obviously this is a prolonged qt, but what are the odds that it is Long QT syndrome? If it isn't, what is it???? I can't find any answers. I do know that it is considered a borderline QT interval until it hits 470. If she doesn't get diagnosed with long qt syndrome (cardiology appointment is next week) Does it just mean that she has a long qt interval and nothing else?
