Can one diaognised with Schizophrenia continue same medicine, namely Olanzapine 10mg for seven years ?

My wife, 47 years old, physically healthy and also suffering from Diabetis (No need for insulin) is diagonised with shizophrenia and taking Olanzapine 10 mg for last seven years. she is under control and no major problem. Should she continue with this medicine or is there a need to change after so many years with same medicine?

I would not mess with something that appears to be working. I have a family member affected too and every time he goes off his medication (alot...) he has major problems with paranoia and hallucinations. I would suggest talking you your wifes doctor for more guidance. GOod luck

if its working why change?

there could be problems with side effects, but that would have already been an issue.
if it aint broke dont fix it good luck and god bless
I used to work with clients diagnosed with schizophrenia. I came to realize that when the doctors messed around with their meds, that's when the problems occurred!

Like the saying goes, "If it ain't broke, don't fix it!"
Plus, 10mg is a really low dose. If anything, they would probably just up it 5-10mg...think long & hard before a doctor talks you/her into changing medication!
I'm sure your wife is monitored with a physican. Does he see it or find it necessary to ask about her side effects and her overrall long term use of this medication? I would always ask if "we're on the right track" or, "has anything new or better out there that we should look into"? And if he's ( your wife, you and him ) are all on the same page and all & all, things are good, then.....why mess, right?
She can continue on the same medication longterm if it is working well for her. Olanzapine does have a known tendency to increase blood sugar and cholesterol so be sure that her psychiatrist is ordering regular lab work for her. Be sure she is also keeping a good record of her blood sugar and taking it for her doctor to review. I am a psychiatric nurse working in an acute crisis stabilization unit.
I do not personally know about that particular medicine, so I hope you do not mind my butting in. :-) My aunt was diagnosed as a paranoid schizophrenic 13 years ago and since then has been on Lithium, Halidol (Ithink that is how you spell it) and many other meds. The most constant has been the Lithium. It keeps her level and from having to go into the hospital. I would have to say that with any meds there are possible effects after long term use, but if it works... Ask your wife's doctor or your pharmacist about ingredients and the effects of long term use. They are required to tell her (or you) if there is a risk of liver damage or something of that nature. I am not sure about the particulars of the medicine you named, but if my aunt can thrive for that long on meds for that particular mental illness, I'm sure your wife will be fine. Good Luck!
