Hello...I was on Invega for some time and experienced sexual dysfunction> I lost my erections, experienced erectile dysfunction. This med was effective for me from the standpoint that my hallucinations went away but it was not cool to be impotent. I was switched to Geodon and it was yet another mess but did pretty well for the hallucinations but I gave up and switched to Seroquel and while on it my hallucinations came back and it became intolerable, my erections on the other hand was not too bad if I recollect properly. So because of the hallucinations I was put on olanzapine (zyprexa) which helped with the ED but the hallucinations remained. I am not sure how well my erections were coping on the zyprexa and Seroquel..........it was just okay. Now I'm on clozapine....this for me has been a phenomenal med, did a great job in shooing away my hallucinations but now I have some other kind of problem which is that I am getting my erections but I'm not able to ejaculate.
