"I wasn't prescribed Zyprexa for OCD, but for psychosis. But since I developed OCD on this med, I wanted to warn people. 

Before Zyprexa I was slightly perfectionist and obsessive, but because of Zyprexa I developed full blown OCD (upon withdrawal). Ever since using Zyprexa I can't function because of obsessions and many other problems that started with Zyprexa. I changed into a completely different person: angry, sad, obsessive, controlling, unkind. 

Zyprexa is said to cause OCD in some 20% or so of it's users. Please stay away from it if you already have OCD...it may worsen it."
