Is there any reccomended medications or treatment for borderline personality disorder?

DBT. Dbt, or dialetic behavioral therapy, formulated and developed by marsha linehan, pH.D. Is currently though of as being very effective. Just about the biggest goal of this kind of therapy for this kind of disorder is to maintain boundaries.
No, but medications. are prescribed for comorbid conditions with anxiety, depression, aggression, psychosis, etc. Long-term psychotherapy is effective for many patients, especially if the family participates. See for good information, though it is from the DSM-IV. DSM-V uses degree of impairment in personality & other areas of functioning.
