It depends on the Type of AP and the dosage and how long you have been on them.. They are a very strong chemical prescribed for psychosis...... so logic tells me that there is a chance if a person suddenly stops, after being on them awhile, there may be a rebound psychosis or icky feeling and who needs that?. I do not know if the new atypical AP's work quickly. From what I read, they take one or two weeks to build up as well. I am not very familiar with typical AP's like Haldol, but I do know that they are used for immediate effectiveness in large doses, like when someone is in a really bad acute psychotic state and needs to be sedated. As far as using Haldol once in a while, maybe look up " efficacy in haldol use as prn". My mother-in-law was prescribed haldol for use when she had hiccups and digestive disorders.... as a prn (as needed). So, maybe it can be used once in a while for mental health reasons too.... For some reason it seams the Dr.s want to have a person on a long term cocktail of meds, instead of treating symptoms when they crop up... I believe the choice is ours.

Let us know what you find out, Newtus. I would like to know. I think the more info. we have, the more power and control we have over our illnesses.

I believe it is best to always taper down off most meds., and I like to ask a good pharmacist that I trust.... they often know more than the prescriber as the pharmacist is a chemist, after all..
