I've taken Geodon and Celexa for a year-and-a-half and have never had an issue with my heart, although I do know about the warnings regarding QT prolongation. I'm concerned that the doc yanked you off the Celexa without tapering it first. My experience with coming off even 10 mg was miserable.....tried it twice, once while manic, and I was a pissed-off, irritable, tearful bundle of anxiety triple-dipped in psycho.

So now I'm on 5 mg forevermore, which is basically just to prevent withdrawal. Higher doses tend to encourage the development of manic episodes, and I'm on enough mood stabilizers to hold back the worst of the depression anyway so the sub-therapeutic dose is basically a place-holder in my med regimen.

Hope things turn around for you soon.
