Thank you very much. I don't need the dosages. Not to worry. Based on everything you've mentioned, both initially and in the follow up questions it sounds as though the induced mania your mother experienced years ago may have manifested a bipolar disorder that had been laying dormant.
First of all...aside from the Klonopin and the Ambien and of course the medicine for her cholesterol she is on the wrong type of medication. She would do much better on a mood stabilizer such as a starting Dose of Zyprexa 5mg or Risperdol 1-2 mg. These two specific medications are listed as antipsychotics but they are actually more used as mood stabilizers and have been found to be effective in the treatment of bipolar disorder.
Some of the more common mood stabilizers would include Depakote or Lithium but both require frequent blood work and they often need to be adjusted too frequently to be of true value.
As for the percocet addiction...It sounds as though she may have started to take more then prescribed to "numb" the emotional pain as is often the case in a misdiagnosis such as this.
In order to get your mother stabilized fully she would need to go inpatient for a couple of reasons. To get her started safely on the medications I mentioned (or another mood stabilizer suggested by her doctor) as she will need time to adjust to those medications. The other reason would be to get her off of the percocet. The reason I say this is that percocet is an opiate which would require a medical detox and can be quite unpleasant.
So at this point I would suggest an inpatient hospitalization for the above mentioned but also to receive an appropriate diagnosis. I know you mentioned there have been several ER visits and they have sent her home....The issue would be no acute suicidality. If she indicates that she is feeling suicidal and DOES NOT feel safe then she will be admitted. From that point upon her further stabilization I would suggest her being put into a dual diagnosis Partial Hospitalization Program which targets both continued stabilization of her mental state as well as addressing the addiction issues...even though it's likely being used as self medicating the chances of her being addicted to them by now are high.
The Partial program would include groups and individual therapy on a daily basis for about 4-5 hours a day. The other good thing would be that she would see a psychiatrist at least twice a week in order to make any adjustments of her medications.
Please let me know if this helps and if you have any further questions or need additional clarification as I want to be certain that all your questions are answered.
