Welcome to HealingWell and the bipolar board. No, MAOI's are a class of antidepressants which aren't used a whole lot any more but do sometimes turn up. Geodon is not one. Your doc would have warned you because to be on a MAOI you have to be on a special diet.
Lexapro and Geodon are not necessarily short-term drugs. If they keep you healthy and steady, then stay on them as long as you need to. That's between you and your doctor.
Hope this helps,
