Buprenorphine, Psychiatric Medications, and Pain Management: An Integrative Approach

Pain and mental health are deeply connected. Did you know that we can help?

Living with chronic pain can contribute to anxiety, depression, sleep problems, irritability, trauma symptoms, and substance use. At the same time, psychiatric conditions can increase the intensity and impact of pain.

For people experiencing both pain and mental health or substance use concerns, treatment does not have to occur in separate silos.

Integrative psychiatry can bring pain management, psychiatric care, and substance use treatment together to address the whole person.

So, while we don't specialize in pain management, we can certainly help!

One medication that has received increasing attention in this area is buprenorphine.

What Is Buprenorphine?

Buprenorphine is a medication that acts on the body's opioid receptors. Unlike traditional full opioid agonists such as oxycodone, hydrocodone, or morphine, buprenorphine is a partial opioid agonist.

This unique pharmacology allows buprenorphine to be used in different clinical contexts, including:

• Opioid use disorder (OUD)

• Opioid withdrawal and craving

• Certain forms of acute pain

• Chronic pain in selected patients

• Pain in individuals who also have a history of opioid misuse or OUD

Buprenorphine is available in several formulations, and different products are approved for different indications. The formulation and dosing strategy should therefore be individualized to the patient's clinical situation.

Why Consider Buprenorphine for Someone With Pain?

Chronic pain can become particularly complicated when someone has developed opioid dependence or opioid use disorder.

Traditional opioid medications can provide analgesia, but long-term opioid therapy carries risks including tolerance, dependence, overdose, and opioid use disorder.

Buprenorphine may offer an alternative for carefully selected patients because it can provide opioid receptor activity while generally producing less respiratory depression than full opioid agonists. Importantly, buprenorphine is still an opioid and is not risk-free.

The CDC notes that buprenorphine can be considered for pain in some circumstances and that overdose remains possible, particularly when it is combined with other respiratory depressants such as alcohol, benzodiazepines, or other opioids.

When Pain and Opioid Use Disorder Occur Together

One of the most important applications of buprenorphine is in individuals who have both pain and opioid use disorder.

A person should not have to choose between treating their addiction and treating their pain.

The CDC recommends that patients with pain and active OUD receive appropriate pain treatment while also receiving effective treatment for OUD. Buprenorphine or methadone may address OUD while also providing some benefit for concurrent pain.

This is an important component of integrative care: treating the substance use disorder does not mean ignoring the pain.

Buprenorphine and the Brain-Pain Connection

Pain isn't exclusively a signal coming from injured tissue.

The experience of pain is influenced by the nervous system, emotions, attention, stress, sleep, previous experiences, and environmental factors.

This is why two people with similar physical conditions can experience dramatically different levels of pain.

Chronic pain can also alter the nervous system's sensitivity to pain signals. Psychological distress may further amplify the experience.

An integrative psychiatric evaluation therefore considers questions such as:

• How long has the pain been present?

• What caused the pain?

• How does pain affect sleep?

• Is depression present?

• Is anxiety contributing to pain-related distress?

• Is there a history of trauma?

• Has opioid tolerance or dependence developed?

• Is there current or previous substance use?

• What medications and supplements are being used?

• What non-medication approaches have been tried?

Ketamine and Pain Management

Ketamine is also an emerging option for certain types of difficult-to-treat pain, particularly neuropathic pain and conditions such as complex regional pain syndrome (CRPS). At lower doses than those used for anesthesia, ketamine can affect NMDA receptors involved in pain signaling and may help reduce abnormal pain processing and central sensitization. Research suggests potential benefits for some individuals with chronic pain, although effectiveness varies by condition and more research is needed to determine who is most likely to benefit.

Ketamine may be especially interesting in integrative psychiatry because chronic pain frequently occurs alongside depression, anxiety, trauma-related symptoms, and sleep difficulties. Ketamine has demonstrated rapid antidepressant effects in certain treatment-resistant conditions and may offer benefits for both mood and pain in carefully selected patients.

Ketamine should not be viewed as a stand-alone cure for chronic pain. It is best considered as one component of a comprehensive treatment plan that may also include psychotherapy, physical therapy, exercise, sleep optimization, medication management, and other non-opioid approaches. Because ketamine can cause sedation, dissociation, changes in blood pressure, and other adverse effects, treatment should be provided with appropriate medical screening, monitoring, and follow-up.

The goal of integrative pain treatment is not simply to eliminate pain, but to help individuals improve function, emotional well-being, and quality of life.

Psychiatric Medications Can Sometimes Help Pain Too

Some psychiatric medications have effects that extend beyond mood and anxiety.

SNRIs

Medications such as duloxetine and venlafaxine increase serotonin and norepinephrine signaling.

Duloxetine, in particular, is used for several pain conditions in addition to depression and anxiety.

For someone experiencing both depression and certain types of chronic pain, a medication that addresses both conditions may be particularly useful.

The CDC notes that SNRIs can improve pain and function in certain chronic pain conditions and that patients with co-occurring pain and depression may particularly benefit from antidepressant treatment.

Tricyclic Antidepressants

Medications such as amitriptyline and nortriptyline may be used in selected patients for certain neuropathic and chronic pain conditions.

They may also have benefits for depression, although their side-effect profiles require careful consideration.

Gabapentin and Pregabalin

These medications affect calcium-channel signaling in the nervous system and are commonly used for certain neuropathic pain conditions.

They may also have roles in treating selected anxiety or substance-use-related symptoms.

However, gabapentinoids are not appropriate for everyone and can cause sedation and dizziness. They can also increase respiratory-depression risk when combined with opioids or other sedating substances.

Other Psychiatric Medications

Depending on the individual, other medications may have a role in treating the psychiatric conditions that can worsen the experience of chronic pain.

For example, effectively treating:

• Depression

• Anxiety

• PTSD

• Insomnia

• ADHD

• Bipolar disorder

may improve functioning and help a person engage more successfully in their overall pain treatment plan.

The Importance of Non-Opioid Pain Treatment

Integrative psychiatry does not mean replacing one medication with another.

Medication should generally be only one component of a comprehensive pain-management strategy.

Current CDC guidance recommends maximizing appropriate nonpharmacologic and nonopioid therapies for subacute and chronic pain before considering opioid therapy.

Depending on the type of pain, treatment may include:

• Physical therapy

• Exercise

• Strength training

• Occupational therapy

• Massage

• Acupuncture

• Yoga

• Tai chi or qigong

• Mindfulness-based stress reduction

• Cognitive behavioral therapy for pain

• Relaxation techniques

• Sleep optimization

• Weight management when appropriate

• Treatment of underlying medical conditions

These approaches can work together rather than being viewed as competing alternatives.

Therapy for Chronic Pain

There now are many types of talk therapies that can target pain and how we view our pain. Pain can also change how a person thinks about themselves and their future.

Someone living with chronic pain may begin thinking:

"I'll never get better."

"My body is broken."

"I can't do anything anymore."

"Nobody understands what I'm going through."

These thoughts can increase distress and, in turn, make pain more difficult to manage.

Cognitive Behavioral Therapy for Chronic Pain (CBT-CP) can help people identify patterns of thinking and behavior that contribute to suffering while developing practical strategies for coping with pain.

Other approaches, including ACT and mindfulness-based therapies, can help individuals develop a different relationship with pain without suggesting that the pain is "all in their head."

Substance Use and Pain

People with substance use disorders deserve compassionate, effective pain treatment.

A history of substance use should not automatically result in a person being denied treatment for legitimate pain.

At the same time, opioid therapy requires careful consideration when there is a history of substance use disorder because the risks of opioid-related harms may be higher.

The CDC recommends considering risk-mitigation strategies, including naloxone and increased monitoring, when opioids are prescribed to individuals with substance use disorders.

An integrative approach may therefore include:

Pain treatment + psychiatric treatment + substance use treatment + safety planning.

Cannabis and Pain

Cannabis and cannabinoids are also sometimes incorporated into integrative pain discussions.

Some patients report improvements in pain, sleep, or muscle tension with cannabis products. However, the evidence varies substantially depending on the condition and cannabinoid preparation. Cannabis can also produce adverse effects, including impaired concentration, anxiety, dizziness, dependence, and withdrawal. However, cannabis is still an option that can help resolve significant pain and improve quality of life.

Cannabis should therefore be discussed as part of the overall treatment plan rather than being automatically considered.

The Goal Isn't Zero Pain

One of the most important shifts in chronic pain treatment is recognizing that successful treatment doesn't always mean eliminating pain completely.

A more realistic goal may be:

Less pain + better sleep + improved mood + increased activity + improved function + greater quality of life.

Someone may still experience pain while becoming more active, sleeping better, returning to work, reconnecting with family, or participating in activities they enjoy.

Those are meaningful treatment outcomes.

An Integrative Pain and Psychiatry Treatment Plan

For an individual experiencing chronic pain, depression, anxiety, and opioid use disorder, an integrative treatment plan might potentially include:

• Buprenorphine treatment when clinically appropriate

• Antidepressant medication targeting mood and/or pain

• Psychotherapy

• Substance use counseling

• Physical therapy

• Exercise and gradual activity progression

• Sleep optimization

• Mindfulness or relaxation techniques

• Nutritional support

• Targeted supplements when appropriate

• Naloxone and overdose-prevention education

• Regular monitoring and coordination with other healthcare providers

The exact combination depends on the individual.

A Different Way to Think About Pain

Pain management and psychiatric care do not need to exist in separate worlds.

For many people, pain affects mood. Mood affects sleep. Sleep affects pain. Substance use may develop as an attempt to cope with all of it.

Breaking that cycle requires looking at the whole person.

Buprenorphine can be an important tool for selected patients, particularly when pain and opioid use disorder overlap. Psychiatric medications may also provide benefits for both emotional symptoms and certain pain conditions. Therapy, physical activity, sleep, nutrition, and other non-medication interventions can further strengthen the treatment plan.

Integrative psychiatry recognizes that treating the mind, brain, body, and behavioral health together may provide a more complete approach to complex pain and recovery.

At Lakeside Integrative Nurse Practitioners in Psychiatry, the focus is on developing individualized, evidence-informed treatment plans that address not only psychiatric symptoms and substance use, but also the physical and emotional burden of chronic pain.

Buprenorphine, opioids, psychiatric medications, cannabis, and other substances can have significant risks and interactions. Buprenorphine should only be initiated or adjusted under the supervision of a qualified clinician. Never combine opioids with alcohol, benzodiazepines, or other sedating substances without explicit medical guidance. Pain treatment should be individualized based on diagnosis, medical history, psychiatric history, substance use history, and treatment goals.
