Ive been prescribed Seroquel for over a year now and have a large amount of family history with Diabetes. My father even passed away from it. Now I have found out that if you have family with it, you aren't supposed to be on this medication!!! It's in my chart that my family has diabetes. I have read up on this medication further now and found out it can increase your chance of developing the disease of you have f.h. ~ does anyone know the chances? PLEASE serious ONLY!
