BPD Medication: A UK Guide to Symptom Relief

Living with Borderline Personality Disorder (BPD) often involves a complex journey towards stability and well-being. While it's crucial to understand that there are currently no medications specifically approved by regulatory bodies in the UK or elsewhere for the direct treatment of BPD, pharmaceutical interventions can play a significant, supportive role. These medications are typically prescribed to help alleviate the challenging and often debilitating symptoms associated with the condition, such as intense mood swings, periods of depression, heightened impulsivity, and aggression.

It's vital to remember that medication is rarely, if ever, a standalone solution for BPD. Instead, it forms part of a holistic treatment plan, almost always used in conjunction with psychotherapy – often considered the first-line treatment. Your healthcare provider will work closely with you to tailor a medication regimen that addresses your unique symptom profile and severity, ensuring close monitoring throughout the process.

Why Medications Are Used for BPD Symptoms

Even without a direct 'cure' medication, the strategic use of pharmaceuticals can significantly improve the quality of life for individuals with BPD. The primary aims of prescribing medication in this context are multi-faceted:

• Reducing Symptom Severity: Medications can help to temper the extreme fluctuations in mood, alleviate depressive episodes, reduce anxiety, and manage stress-related paranoia, making daily life more manageable.
• Improving Functioning: By lessening the intensity of symptoms, individuals may find it easier to engage in relationships, maintain employment, and handle daily responsibilities, leading to an overall improvement in their functional capacity.
• Preventing Symptom Worsening: Untreated BPD symptoms can sometimes escalate. Medication can act as a stabilising force, potentially preventing a decline in mental health and the exacerbation of distressing behaviours.
• Treating Co-occurring Conditions: BPD frequently co-exists with other mental health disorders, such as major depressive disorder, anxiety disorders, eating disorders, substance use disorders, and bipolar disorder. Medications can effectively treat these concurrent conditions, which in turn can ease the overall burden of BPD symptoms.
• Decreasing the Risk of Self-Harm and Suicide: BPD is associated with a heightened risk of self-injurious behaviour and suicidal ideation. By reducing the frequency and severity of symptoms that contribute to distress, medications can potentially lower this critical risk.
• Improving Treatment Adherence: When symptoms are better managed, individuals may find it easier to engage with and benefit from psychotherapy, making the entire treatment process more effective.

Classes of Medications Commonly Prescribed for BPD Symptoms

While no specific BPD medication exists, several classes of drugs are frequently used off-label to target particular symptoms. These include antidepressants, mood stabilisers, antipsychotics, and anxiolytics. The choice of medication depends heavily on the individual's specific symptoms and needs.

Antidepressants

Antidepressants are among the most commonly prescribed medications for people with BPD, with studies indicating that a significant proportion of patients receive them. They are primarily aimed at improving low mood, sadness, and anxiety, though their effect on other BPD symptoms like anger or impulsivity is less pronounced.

Selective Serotonin Reuptake Inhibitors (SSRIs)

SSRIs work by increasing the levels of serotonin in the brain, a neurotransmitter believed to positively influence mood, sleep, and emotional regulation. Their side effects are generally mild and often temporary.

• Fluoxetine (Prozac): Has shown mild improvements in affective BPD symptoms, anger, and impulsive aggression, particularly in men and individuals with high levels of impulsive aggression.
• Fluvoxamine (Luvox): May lead to mild improvement in affective instability, though not significantly on impulsivity.
• Paroxetine (Paxil): Limited research suggests a potential decrease in suicidality, without strong effects on depression.
• Sertraline (Zoloft): Another commonly used SSRI for mood and anxiety symptoms.

Monoamine Oxidase Inhibitors (MAOIs)

MAOIs were some of the earliest antidepressants. They work by preventing the breakdown of neurotransmitters like norepinephrine, serotonin, and dopamine. While effective, they have more side effects and require strict dietary restrictions to avoid potentially dangerous blood pressure spikes.

• Phenelzine (Nardil): Shown to improve depression and impulsive aggression in BPD, though it can cause uncomfortable activation.
• Tranylcypromine (Parnate): Some studies suggest improvements in affective symptoms and interpersonal sensitivity.

Other Antidepressants

• Venlafaxine (Effexor): A serotonin-norepinephrine reuptake inhibitor (SNRI) that may help with mood and anxiety.
• Bupropion (Wellbutrin): A norepinephrine-dopamine reuptake inhibitor (NDRI) often used for depression.

Mood Stabilisers and Antiseizure Medications

Often used in the treatment of bipolar disorder, mood stabilisers and antiseizure medications (ASMs) are prescribed to manage BPD symptoms such as anger, rapid mood swings, and impulsivity. Approximately 36% of BPD patients are reported to take mood stabilisers.

• Carbamazepine (Tegretol): Can reduce impulsivity, but caution is needed as it may worsen melancholic depression.
• Divalproex Sodium (Depakote): Improves interpersonal sensitivity, irritability, and aggression, particularly in individuals with high impulsive aggression.
• Lamotrigine (Lamictal): May help with anger, affective instability, and impulsivity, but carries a risk of a severe, potentially life-threatening rash.
• Lithium Carbonate (Lithobid): Limited research indicates potential improvement in affective instability and overall functioning.
• Topiramate (Topamax): Can improve anger, anxiety, interpersonal dysfunction, and self-reported quality of life. However, its side effect of weight loss might be problematic for some.

Antipsychotics

Antipsychotics, both typical and atypical, are sometimes used to manage anger, impulsive aggression, affective instability, and perceptual disturbances common in BPD. However, the long-term risk-benefit profile of these drugs for BPD is not always clear.

Typical Antipsychotics

These older antipsychotics have been used, but data on their effectiveness for BPD is often limited.

• Fluphenazine Decanoate (Prolixin Decanoate): Limited data, but used for suicidality and self-injurious behaviour in some cases.
• Haloperidol (Haldol): May improve paranoia and anger, and potentially anxiety and affective symptoms, but can increase sedation and depression.
• Loxapine (Loxitane): Suggested to be effective for depression and anger in some BPD patients.
• Thiothixene: Some research supports its use for cognitive-perceptual symptoms and psychoticism.

Atypical Antipsychotics

These newer antipsychotics are more commonly used due to a generally better side effect profile, though they still carry significant risks.

• Aripiprazole (Abilify): Improves affective symptoms, aggression, paranoia, and overall functioning.
• Olanzapine (Zyprexa): Can improve mood swings, impulsivity, aggression, and interpersonal sensitivity, but carries a high risk of weight gain and metabolic issues.
• Risperidone (Risperdal): Another atypical antipsychotic sometimes used for impulsivity and aggression.
• Quetiapine (Seroquel): May help with mood instability and sleep.

Despite some evidence of symptom improvement, typical antipsychotics are associated with a risk of worsening overall BPD symptoms and require close monitoring due to side effects like tardive dyskinesia.

Anxiolytics (Anti-Anxiety Drugs)

For individuals experiencing intense, prolonged anxiety, anti-anxiety medications may be prescribed. They typically work by increasing GABA, a natural calming agent in the brain.

While potentially useful during periods of extreme agitation, there is limited research supporting their long-term use for BPD, and caution is advised with benzodiazepines due to risks of dependence and potential symptom worsening.

• Lorazepam (Ativan): A benzodiazepine that enhances GABA effects for a calming action.
• Clonazepam (Klonopin): Approved for panic disorder, sometimes used off-label for anxiety in BPD.
• Diazepam (Valium): Commonly used for anxiety, seizures, and alcohol withdrawal.
• Alprazolam (Xanax): Used for anxiety and panic disorders.
• Buspirone (Buspar): A non-habit-forming anxiolytic, which can be a safer alternative to benzodiazepines for long-term anxiety management, though it takes longer to become effective.

Sudden cessation of benzodiazepines can lead to severe withdrawal symptoms, including seizures. It is paramount to always consult your doctor before making any changes to your medication.

Table of Common Medication Classes and Their Target Symptoms

Novel Treatments Under Investigation

Researchers are continuously exploring new avenues for managing BPD symptoms, looking beyond the traditionally used medication classes:

• Omega-3 Fatty Acids: These dietary fatty acids are being studied for their potential benefits in reducing impulsivity and aggression, and are considered safe, even for those with co-occurring substance use disorders.
• Opioid Antagonists: Early research suggests these might help reduce self-harm behaviours, though more evidence is needed.
• Vasopressin Antagonists: Investigations are looking into the link between vasopressin levels and aggression/irritability in BPD, with potential for new targeted treatments.
• Histone Deacetylase Inhibitors: These drugs aim to reverse biological changes from early life stress, a known risk factor for BPD, potentially offering a novel therapeutic approach.

Other Essential BPD Treatments

While medication can alleviate symptoms, the cornerstone of BPD treatment is psychotherapy. Several specialised forms of talk therapy have proven highly effective:

• Dialectical Behaviour Therapy (DBT): Widely considered the gold standard, DBT helps individuals develop coping skills for emotional regulation, distress tolerance, interpersonal effectiveness, and mindfulness.
• Cognitive Behavioural Therapy (CBT): Including programmes like Systems Training for Emotional Predictability and Problem Solving (STEPPS), CBT helps identify and change unhelpful thought patterns and behaviours.
• Schema-Focused Therapy: Aims to help people with BPD alter deeply ingrained, unhelpful worldviews and beliefs.
• Mentalisation-Based Treatment (MBT): Helps individuals understand their own and others' mental states, improving relationships.
• Dynamic Deconstructive Psychotherapy (DDP): A longer-term programme for those who haven't found other therapies effective.
• Transference-Based Psychotherapy (TFP): Focuses on understanding and improving relationship patterns and avoiding 'splitting' (seeing others as all good or all bad).

Potential Side Effects of BPD Medications

Like all medications, those used for BPD symptoms come with potential side effects. These vary greatly depending on the specific drug and individual physiology, but some common ones to be aware of include:

• Weight changes (gain or loss)
• Dry mouth
• Feeling sleepy (sedation) or fatigued
• Trouble sleeping (insomnia)
• Dizziness or lightheadedness
• Sexual side effects
• Constipation or nausea

Less common but more serious side effects can include involuntary movement disorders (like tardive dyskinesia), restlessness, changes in blood test results (e.g., cholesterol), confusion, or even a worsening of depression, anxiety, or suicidal thoughts. It is imperative to discuss any new or concerning side effects with your healthcare provider immediately.

Important Precautions and Considerations

Before starting any medication for BPD symptoms, a thorough discussion with your healthcare provider is essential. Several factors need careful consideration:

• Pregnancy and Breastfeeding: Some medications may not be safe during pregnancy or breastfeeding due to potential risks to the developing foetus or infant. Always inform your doctor if you are pregnant, planning to conceive, or breastfeeding.
• Existing Medical Conditions: Certain health conditions can affect how your body processes drugs, potentially requiring dosage adjustments or a different medication choice.
• Drug Interactions: It's crucial to inform your doctor about all other medications, over-the-counter products, and herbal supplements you are taking to avoid potentially dangerous interactions.
• Never Stop Suddenly: Do not change your dose or abruptly stop taking any BPD medication without first consulting your doctor. Sudden cessation, especially of benzodiazepines or some antidepressants, can lead to severe withdrawal symptoms or a rebound of symptoms.
• Cost of Medication: The cost can vary based on the specific drug, whether it's brand-name or generic, dosage, and your insurance coverage. If cost is a barrier, discuss it with your provider; they may be able to suggest more affordable alternatives or direct you to support programmes.

Coping with BPD Beyond Medication

Living with BPD presents unique challenges, but a strong support system, including loved ones and healthcare professionals, can significantly aid in navigating these difficulties. Beyond prescribed medications and psychotherapy, adopting health-promoting habits is crucial for managing BPD symptoms and improving overall well-being:

• Develop Healthy Coping Skills: Learning effective strategies for emotional regulation, managing distress, and improving interpersonal relationships, often taught in DBT, can be life-changing.
• Prioritise Self-Care: Regular physical activity, a nutritious diet, adequate sleep, and stress-reduction techniques (like mindfulness or deep breathing) contribute significantly to mental stability.
• Seek Support: Don't hesitate to reach out to your support network or mental health professionals if you feel your treatment needs adjusting or if you're struggling.
• Treat Co-occurring Conditions: Actively addressing any other mental health conditions, such as substance use disorders or PTSD, can make managing BPD symptoms much more effective.

Frequently Asked Questions (FAQs)

Are medications the first-line treatment for BPD?

No, psychotherapy (talk therapy), particularly Dialectical Behaviour Therapy (DBT), is widely considered the first-line and primary treatment for Borderline Personality Disorder. Medications are typically used as an adjunctive treatment to help manage specific symptoms that are part of BPD or co-occurring conditions, rather than treating BPD directly.

Why is BPD called a 'borderline' disorder?

The term 'borderline' originated from early psychiatric theories. Psychiatrists once believed that the symptoms of BPD lay "on the border" between neurosis (characterised by anxiety and distress, but reality remains intact) and psychosis (characterised by a break from reality, such as hallucinations or delusions). While this original conceptualisation is now outdated, the name has persisted.

What drugs are used in the treatment of BPD?

While no specific drug is approved to treat BPD itself, medications are used off-label to target specific symptoms. The main classes of drugs include antidepressants (e.g., SSRIs like fluoxetine), mood stabilisers (e.g., lamotrigine), antipsychotics (e.g., aripiprazole), and anxiolytics (e.g., buspirone). The choice depends on the individual's symptoms and needs.

Can I stop taking my BPD medication if I feel better?

It is critically important never to stop taking your BPD medication suddenly or to change your dosage without first consulting your healthcare provider. Abruptly stopping certain medications can lead to severe withdrawal symptoms, a relapse of symptoms, or other adverse effects. Your doctor will guide you on how to safely adjust or discontinue medication if appropriate.

In summary, while there isn't a single pill for BPD, a well-managed medication plan, integrated with robust psychotherapy and self-care strategies, can significantly improve the lives of those living with Borderline Personality Disorder. Always maintain open communication with your healthcare team to ensure the most effective and safe treatment approach for your individual needs.
