Hi. I strongly agree with Miguel's Mom. BP is a 2part problem that needs to be treated equally for both of it's parts. My doc and I are aware that my AD may trigger my mania but I know the warning signs and to back off on it or stop it if it gets too bad. Right now my depression bad enough that it is worth the risk of triggering any manic symtpoms. There are so many AD's out there that I think it's possible to find one that doesn't trigger you. Effexor and Cymbalta have both worked well for me in the past. If I was on an upswing, I would just decrease my dose. When I was on a downswing, I would go back to maximum dose. It's all about being self-aware of your warning signs and addressing both states depending on how good or bad they are at the time. \
If you can get by just taking a MS that would be best, but if you need an AD for your depression, then just keep trying out different ones till you find one that suits. It can and does take years to get meds right for BP. Don't give up or lose hope. It just takes time.
Good luck, take care and keep us posted on your progress and any developments.
