Opioid Use Disorder Overview

Opioid use can begin with prescription painkillers. When use of these powerful substances becomes an addiction, life can spiral out of control, threatening a person’s physical, mental, and social wellbeing. Family and friends are often the first to recognize the wide-ranging signs of opioid abuse.

Opioid use disorder is a pervasive and complex medical condition that significantly impacts the lives of those affected. It manifests as an unrelenting cycle of seeking opioids, consuming them, recovering from their effects, and then beginning the cycle anew. This disorder is often protracted, characterized by intermittent phases of recovery and relapse. Its diagnosis hinges on the presence of specific symptoms, and it is typically managed through a combination of medications and behavioral interventions. The opioid crisis in the United States has escalated to epidemic proportions, leading to its declaration as a Public Health Emergency in 2017, with nearly 50,000 Americans succumbing to opioid overdoses that year. In this comprehensive discussion, we will delve deeper into opioid use disorder, examining its causes, symptoms, types, diagnosis, treatment, and prevention strategies.

Understanding Opioid Use Disorder

Opioids, potent pain-relieving substances, are typically prescribed by healthcare professionals following injuries, surgeries, dental procedures, or cancer diagnoses. Examples of opioids include heroin, morphine, fentanyl, and oxycodone. While individuals may initially use opioids for legitimate medical reasons, opioid use disorder emerges when the consumption spirals out of control. As tolerance builds, individuals require increasingly higher doses to attain the same pleasurable or euphoric effects. This escalation often leads to strained relationships, financial difficulties, and even criminal activities.

Types of Opioid-Related Conditions

It is essential to distinguish between drug tolerance, drug dependence, and drug use disorder or addiction. Drug tolerance and dependence can occur without the accompanying mental obsession seen in addiction. In contrast, opioid use disorder, synonymous with addiction, entails the domination of an individual’s life by opioids, leading to an overwhelming belief that life cannot continue without these substances. The severity of opioid use disorder is directly related to the number and intensity of symptoms experienced.

Symptoms of Opioid Use Disorder

Identifying signs of opioid abuse can be challenging, but friends and family members often notice them before the affected individual does. These symptoms include:

  1. Inability to stop using opioids.
  2. Overwhelming cravings.
  3. Drowsiness.
  4. Altered sleep patterns.
  5. Weight loss.
  6. Flu-like symptoms such as muscle aches.
  7. Dramatic mood swings.
  8. Slurred speech.
  9. Constipation.
  10. Agitation.
  11. Irritability.
  12. Reduced coordination.
  13. Slow or shallow breathing.
  14. Decreased sex drive.
  15. Poor hygiene.
  16. Social isolation.
  17. Engagement in criminal behavior, such as theft.
  18. Financial problems.
  19. Apathy.
  20. Anxiety attacks.

Opioid overdose symptoms are particularly alarming and potentially life-threatening, encompassing:

  1. Unresponsiveness to stimuli.
  2. Slow, irregular, or halted breathing.
  3. Slow, irregular, or absent pulse.
  4. Vomiting.
  5. Constricted pupils.

Furthermore, individuals experiencing opioid withdrawal may encounter intense cravings and anxiety, coupled with abdominal cramps, diarrhea, elevated blood pressure, sweating, shakiness, insomnia, and dilated pupils.

Complications and Health Risks

The use of opioids, particularly through injection, escalates the risk of encountering serious health issues, including HIV, hepatitis B, and hepatitis C. These complications underscore the importance of addressing opioid use disorder promptly.

Causes of Opioid Use Disorder

Addiction, including opioid use disorder, is an intricate condition influenced by genetic, biological, and environmental factors. Several key factors contribute to the development of opioid use disorder:

1. Access to Medications: The rising number of opioid prescriptions has contributed significantly to the prevalence of opioid addiction. Shockingly, up to 12% of individuals prescribed opioids for chronic pain may develop opioid use disorder. Furthermore, individuals without prescriptions can also be drawn into this cycle.

2. Environmental Factors: Socioeconomic status and living in rural areas have been associated with a higher likelihood of opioid use disorder. Poverty and limited access to healthcare services can compound the problem.

3. Biological Factors: Some individuals may use opioids to self-medicate for deficiencies in dopamine and other neurotransmitters in the brain. A history of depression, anxiety, childhood trauma, or post-traumatic stress disorder (PTSD) can elevate the risk of developing opioid use disorder.

4. Genetic Predisposition: While scientists continue to unravel the specific genes involved in opioid use disorder, research indicates that individuals with a first-degree relative (such as a child, parent, or sibling) with a similar disorder are more susceptible to opioid abuse. Additionally, men are at a higher risk than women, and older individuals (between the ages of 40 and 50) are more prone to fatal overdoses.

Diagnosing Opioid Use Disorder

Diagnosing opioid use disorder is a complex process that relies on comprehensive medical history assessment, including any underlying health conditions that may predispose an individual to substance abuse. One of the challenges in diagnosis is that many individuals with opioid use disorder may not acknowledge their problem. Moreover, healthcare professionals must determine whether individuals are taking prescription opioids for legitimate reasons. The Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (DSM-5), outlines criteria for opioid use disorder diagnosis, requiring the presence of at least two of the following 11 problems within a one-year period:

  1. Spending excessive time on obtaining, using, or recovering from opioids.
  2. Neglecting other activities in favor of opioid use.
  3. Experiencing strong cravings for opioids.
  4. Using opioids in larger amounts or for longer durations than intended.
  5. Unsuccessful attempts to control opioid use.
  6. Continued opioid use despite social or personal problems linked to their use.
  7. Continued opioid use despite deteriorating physical or psychological health.
  8. Difficulty meeting work, school, or personal obligations due to opioid use.
  9. Developing tolerance to opioids, requiring higher doses for the same effect.
  10. Experiencing withdrawal symptoms when not using opioids.
  11. Using opioids in risky situations.

The severity of the disorder correlates with the number of symptoms present.

Treating Opioid Use Disorder

Managing opioid use disorder is multifaceted, with no one-size-fits-all approach. Effective treatment typically involves a combination of medications and behavioral interventions, offered in either inpatient or outpatient settings. The Food and Drug Administration (FDA) has approved three medications to address opioid use disorder:

1. Methadone: Methadone serves as a substitute for opioids, blocking the pleasurable effects of opioids while reducing cravings and withdrawal symptoms. This medication requires long-term maintenance and is administered in specialized medical settings.

2. Buprenorphine: Similar to methadone, buprenorphine acts as a maintenance therapy, alleviating cravings and withdrawal symptoms while preventing the mood-altering and pain-relieving aspects of opioids.

3. Naltrexone: Naltrexone operates by blocking the euphoric effects of opioids and is available in clinical settings. It can only be prescribed to individuals who have been opioid-free for at least seven days.

In addition to medication-assisted therapy, counseling and behavioral therapies are integral components of treatment. Healthcare professionals also strive to identify and address any underlying mental health issues that may contribute to opioid use disorder.

Preventing Opioid Use Disorder

Prevention is paramount in addressing the opioid crisis. The best approach for individuals is to avoid opioid use altogether. If prescribed an opioid for pain management or other medical conditions, individuals should limit use to one week or explore alternative non-opioid therapies. It is essential to engage in open dialogue with healthcare providers about the necessity and potential risks associated with opioid use.

The wide availability of prescription opioids has fueled the opioid epidemic in the United States. As a response, efforts are underway to combat this crisis. These initiatives include improving access to treatment, restricting the availability of prescription opioids, promoting more effective pain management strategies, and educating both physicians and patients about the risks associated with these medications.

Conclusion

Opioid use disorder is a multifaceted and pervasive public health issue that has reached epidemic proportions in the United States. Understanding its causes, symptoms, types, diagnosis, treatment, and prevention strategies is crucial for addressing this crisis. By combining medical interventions, behavioral therapies, and prevention efforts, we can work towards reducing the devastating impact of opioid use disorder on individuals, families, and communities. It is a complex challenge, but with continued research, education, and support, we can make significant strides in combating this pressing issue.
