Thanks for your query at DoctorSpring. I have gone through what you have stated and I can understand what you are going through.
Citalopram is a good drug since ages and the routine dosages are around 20 mg. It does cause some cardiac worry above 20 mg but then they are quite rare. In fact many of my patients are also doing good on 30mg of citalopram. But one caution I take is that I do a repetitive ECG of my patients and try to monitor the QTc interval. If it is to cause the problem the same is reflected on the ECG and hence caution can be taken. Probably it will make you feel better that I did not notice any changes in QTc interval with citalopram 30 mg inspite of me being cautious.
So I think that is fine.
You should also insist your psychiatrist to consider your for cognitive behavioural therapy along with the medications. That will help in not further increasing your medication dosage.
Hope that helps
