Overview of Stimulant Abuse and Intoxication Delirium

Stimulant abuse can lead to various psychological and physiological symptoms, including agitation, hallucinations, and delirium. The intoxication delirium associated with stimulants can be particularly severe, necessitating urgent medical attention to manage both the acute symptoms and the underlying substance use disorder[1][2].

Standard Treatment Approaches

1. Medical Management

Acute Care

• Emergency Intervention: Patients presenting with intoxication delirium may require hospitalization, especially if they exhibit severe agitation, psychosis, or suicidal ideation. Medical professionals often monitor vital signs and provide supportive care in a controlled environment[3].
• Sedation: Benzodiazepines, such as lorazepam or diazepam, are commonly used to manage severe agitation and anxiety. These medications can help stabilize the patient and reduce the risk of harm to themselves or others[4].

Symptom Management

• Antipsychotics: In cases where psychotic symptoms are prominent, atypical antipsychotics (e.g., olanzapine or quetiapine) may be administered to alleviate hallucinations and delusions[5].
• Hydration and Nutrition: Ensuring adequate hydration and nutrition is crucial, as stimulant use can lead to dehydration and malnutrition. Intravenous fluids may be necessary in severe cases[6].

2. Psychological Interventions

Cognitive Behavioral Therapy (CBT)

• Therapeutic Support: Once the acute phase has passed, engaging the patient in CBT can help address the cognitive distortions and behavioral patterns associated with stimulant abuse. This therapy focuses on developing coping strategies and addressing triggers for substance use[7].

Motivational Interviewing

• Enhancing Motivation: This client-centered approach can be effective in encouraging individuals to recognize the need for change and to commit to treatment. It is particularly useful in the early stages of recovery[8].

3. Substance Use Disorder Treatment

Rehabilitation Programs

• Inpatient or Outpatient Treatment: Depending on the severity of the abuse and the individual’s circumstances, structured rehabilitation programs may be recommended. These programs often include a combination of medical care, counseling, and support groups[9].

Support Groups

• Peer Support: Participation in support groups such as Narcotics Anonymous (NA) can provide ongoing support and accountability, which are crucial for long-term recovery[10].

4. Long-term Management

Relapse Prevention

• Continued Therapy: Ongoing therapy and support are vital to prevent relapse. This may include regular follow-ups with healthcare providers and continued participation in support groups[11].
• Lifestyle Changes: Encouraging healthy lifestyle changes, such as regular exercise, a balanced diet, and stress management techniques, can also support recovery and reduce the risk of relapse[12].

Conclusion

The treatment of ICD-10 code F15.121: Other stimulant abuse with intoxication delirium requires a multifaceted approach that addresses both the immediate medical needs and the long-term psychological and social aspects of recovery. By integrating medical management, psychological interventions, and support systems, healthcare providers can effectively support individuals in overcoming stimulant abuse and achieving lasting recovery.
