Hello, I am taking 40 mg of Geodon twice a
unlikely while using current dosage
Thanks for using Healthcaremagic.
I read your query and understand your concerns about prolongation of QT interval.
First of all I like to acknowledge that your fear is based on the facts and it is always wise to follow recommendations of your doctor. When you are on these medications it is advisable to obtain baseline ECG and repeat the same every three to six months. Any form of sudden changes in heart beat, palpitations, fainting should be reported to your doctor.
Now regarding your question I must assure you that there are multiple causes among the persons who experience QT prolongation such as male gender, use of drugs affecting cardiac conduction, existing QT, elderly, recent history of myocardial infarction among others.
In addition the QT interval prolongation is dose dependent side effect and none of your current medications fall in abnormal range of dosing. There is good possibility that even with prolonged use of these medications prolongation of QT interval is unlikely.
However I will request you to attach your latest ECG along with previous ECG so I can state clearly whether there is any effect on cardiac conduction.
I hope this helps you.
Feel free to write back to me if you have more questions.
Thanks and regards.
