Adding one medication at a time, or making one major medication change at a time, basically, is the sign of a good psychiatrist.

Inderal [propranolol] is a basic medication with a pretty low side effect profile.

Abilify can sometimes be activating and/or have some anxiety effects.
Propranolol can help with tremors but also with anxiety that has physical manifestations.

You don't want to take a person off zoloft and add abilify and propranolol at the same time- then you have no idea if anything is helping or not or what might be helping or causing bad effects. Keeping it simple is the best way to figure out if something is actually helping. Depending on the specific side effects the Zoloft was causing he may want to see what will pan out over the next couple of weeks.

Abilify can also serve to augment SSRIs and aid in treatment of depression in conjunction with them.

Though introducing a moodstabilizer is typical, not everyone will actually need one, particularly with treatment of bipolar II. Particularly if hypo/manias tend to be more dysphoric, one is being treated for symptoms of anxiety, and on an AP [abilify is one that covers some strange symptoms so may in fact cover a lot of ground in a situation like this].

Let us remember that though there are specifiers of BP I, BP II and BPNOS [Not Otherwise Specified], we all kind of have our specific needs and individual details that need tending to.

OP- It can take time to do medication changes. Maybe ask if you can go with her and go into the end of the appointment to get a quick summary of changes and why they are happening. Then she can get some privacy but you can all be on the same page as far as what is going on with meds?
