hi and welcome to PC. I'm sorry that you are suffering with depression.I have been there many times. I was diagnosed with BP II after yrs. of depression. Generally a mood stabilizer is necessary & prescribed along with an anti-dep. or anti-psychotic. As far as I know, neither of the drugs you are taking are mood stabilizers. An anti-dep. alone can cause serious problems for someone with BP.
Sorry, I do not know what IOP stands for. This is a great website to find support. Also, there is a lot of helpful info about drugs and various mental health conditions.
