Some ADs can cause arrhythmia at a certain dose. My pdoc told me that lexapro, which I take, can start to run into that territory so she is careful to keep it below a certain dose for me. She doesn't take chances with any of this stuff. I feel fortunate to have her because I've had pdocs in the past that did not give a rip what the side effects or risks were. They weighed everything against suicide. This one that I'm seeing wants me to have a life worth sticking around for.

Please ask your pdoc of Prozac is one of these meds and find out what the cutoff dose is.
