Is it safe to take brain-enhancing multivitamin supplements w/ pharmacetuical drugs such as zyprexa (olanzapine)? also do side effects from zyprexa (olanzapine) fade over time?

Probably, sometimes: Research has shown high doses of vit c, e, b3 ; b6 prevent tardive dyskinesia, a serious possible side effect of zyprexa (olanzapine). I don't know what's in the supps you're considering but there are no interactions between zyprexa (olanzapine) ; nutrients to the best of my knowledge so it's likely safe.As for side effects, sometimes they fade over time but unfortunately not always. Reducing dose often helps-see comment:.
