Medications used to treat borderlines should focus on the symptoms in the context of a therapeutic approach. Here is a head to trial using Gunderson's psychodynamic method and medications.

I think Linehan has done great work but really she just found a way to approach borderlines. It is an amazing approach for which she deserves a lot of credit. However, you can make that approach with many kinds of therapy and meds can definitely help. SSRIs are better than mood stabilizers because they are safer but if you need a mood stabilizer or an antipsychotic, the SSRI is not going to work.
