Medications commonly used for people with BPD/HPD/PTSD/OCD

There are tons of medications used for BPD, though technically they're prescribed in most cases for specific symptoms of BPD rather than the disorder itself. There is no miracle drug or 'cure' for BPD, though with therapy and a lot of hard work you can reach a level of recovery. Instead, drug therapies are used to combat depression, anxiety, extreme mood swings, insomnia, etc.

I'm a firm believe that a pill is not the answer to your problems. I do not agree with providers who shove heavy duty drugs down their patient's throats before even knowing his/her story. I actually used to be one of the people who thought, "I don't need a damn pill to take so that I can fake being happy, I don't want to rely on medications, etc.", but as I learned more and talked to more people about their experiences and tried a few meds myself, I realized that they can be a very helpful aspect of healing.

Medications commonly prescribed to patients with BPD

Antidepressants:There are two main types of antidepressant drugs, monoamine oxidase inhibitors (MAOI's) and seratonin reuptake inhibitors (SSRI's). These drugs can help with the depression, low mood, lack of energy, and anxiety associated with BPD, HPD, and PTSD but hasn't been shown to reduce other symptoms such as impulsivity, anger, etc. Some of the most common antidepressants prescribed are Nardil (phenelzine), Prozac (fluoxitine), and Zoloft (sertraline).

Antipsychotics:These medications were originally created for the psychotic disorders, but over time have been used for non psychotic disorders such as BPD. They can be some of the most helpful medications for borderlines and histrionics, and personally I've had really great results with one of them. These types of drugs typically help with impulsivity, rage, paranoid thinking, anxiety, 'splitting', and obsessive thought (OCD)s. Some have a side effect of sleepiness and so can also help with insomnia. Some of the most common are Haldol (haloperidol), Zyprexa (olanzapine), Risperdal (risperidone), and Seroquel (quetiapine).

Mood Stabilizers/Anticonvulsants: These medications have been shown to help control the extreme mood shifts, 'splitting', and impulsivity of people with BPD and HPD. The most commonly prescribed are Lithobid (lithium carbonate), Depakote (valproate), and Lamictal (lamogtrigine). 

Anxiolytics (Anti-anxiety): As the name suggests, these medications tend to be prescribed mainly for anxiety; and most often for cases in which extreme anxiety or panic is seen as a few of these drugs can be addictive. Mostly anxiolytics are not recommended to be taken on a regular schedule, but on an as needed basis. Great results can be achieved when used sparingly. I personally have used Ativan in the past on a few occasions and it worked amazingly. A few of the most commonly prescribed are Ativan (lorazepam), Klonopin (clonazepam), Xanax (alpazolam), Valium (diazepam), and Buspar (buspirone).
