Hopeful camel - Aside from the atypical antipsychotics having slightly different mechanisms of action, the reason to use multiple medications can be to reduce the secondary effects of the medication. All medications have a slightly different side effect profile, so by using more than one can reduce the the side effects.

I would ask your psychiatrist if this is why he/she is using multiple medications. Prescribing is an art in that physicians rely on past experience to find the medication(s) that are most effective for your specific needs.

As for feeling bad, could you expand on that? Things like tiredness or lack of energy are common start up side effects and usually go away over time. This could be one of the reasons that he/she is using the three atypicals. You would have to ask him/her, though.

I hope that this is of some help. - Cam
