Hi rovers95,
."BP is thought of as a "spectrum." disorder. It is clear that people do not have their illness play out exactly the same. Someone with BPII might need an anti-psychotic, while another person with a BPII diagnosis may never need an AP. Some people with BPII may only very rarely experience hypomania and, in these cases, concern about instigating hypomania is not at the top if the list of concerns.
I have used low dose APs for depression in the past. I did not have good luck with them. I am now on a dopamine agonist called "Mirapex." I am having very good luck with this med. It is my goal to get off of any AP and rely upon Lamictal (a mood stabilizer) and some Mirapex as needed for depressive episodes.
I wish you luck in finding out which meds and which doses work best for you!
