Overview
Methamphetamine dependence involves compulsive use despite harmful consequences, affecting cognitive, behavioral, and physical health. Prenatal exposure can lead to significant developmental issues in children 1.Diagnosis
History and Screening: Comprehensive history including substance use patterns 2.
Toxicology Screening: Urine toxicology testing with maternal consent for confirmation 2.
Clinical Presentation: Agitation, psychosis, and violent behavior in acute intoxication 3.Management
Chemical Restraint:
- Droperidol: Intravenous administration for sedation in acute intoxication; effective with fewer repeat doses compared to lorazepam 3.
- Lorazepam: Intravenous use for sedation; may require more repeat doses 3.
Treatment Referral: Refer women using methamphetamine during pregnancy for specialized treatment programs 2.Special Populations
Pregnancy:
- Risk Assessment: Increased risk of low birth weight, small for gestational age, and neurodevelopmental problems in offspring 12.
- Monitoring: Serial ultrasound examinations to assess fetal growth 2.
Pediatrics: Prenatal exposure linked to poorer intellectual functioning, problem-solving skills, short-term memory, and language development 1.Key Recommendations
Screen Pregnant Women for methamphetamine use and provide counseling on risks; screen with urine toxicology with consent 2 (Evidence: Strong).
Refer Pregnant Users to treatment programs and monitor fetal growth with serial ultrasounds 2 (Evidence: Strong).
Use Droperidol as first-line for chemical restraint in acute methamphetamine intoxication due to superior sedation profile 3 (Evidence: Moderate).References
