Iv'e been taking olanzapine for 2 years and now i changed to zolofast, while it affect me?

Ziprasodone? Zoloft (sertraline)?: I'm sorry, but i don't know a medicine called "zolofast." could you maybe mean "zoloft, " an ssri antidepressant? Or perhaps ziprasodone (trade name, geodon), an antipsychotic like Olanzapine is? Also, the trade name for Olanzapine is "zyprexa". So there are 3 psychiatric medications that begin with "z" but i don't know which you mean. Can you please look at the bottle and ask again? Thanks.
