From the Guidelines

Cocaine use combined with purging behaviors poses a significant risk to life due to severe electrolyte imbalances, and immediate medical attention is crucial to prevent life-threatening complications. The primary concern with cocaine use and purging is the development of dangerous cardiac arrhythmias, seizures, and other complications due to electrolyte imbalances, as noted in the management of patients with cardiac arrest or life-threatening toxicity due to poisoning 1.

Key Electrolyte Imbalances

  • Hypokalemia (low potassium)
  • Hyponatremia (low sodium)
  • Hypochloremia (low chloride)

These imbalances are exacerbated by cocaine's effects on the body, including its sympathomimetic toxidrome, which leads to increased psychomotor activity, diaphoresis, and other systemic effects 1. Purging behaviors further deplete the body of essential electrolytes, creating a potentially lethal combination.

Treatment Approach

Treatment for severe cases typically involves intravenous (IV) fluid replacement with appropriate electrolytes, such as potassium chloride, sodium chloride, and magnesium sulfate as needed. The dosage for potassium chloride can range from 10-20 mEq/hour for severe deficiencies. For less severe cases, oral rehydration with electrolyte solutions can be an effective approach.

Underlying Mechanisms and Recovery

The underlying mechanism involves cocaine's stimulant effects, which increase sweating and metabolic demands, while purging directly removes electrolytes from the body. Additionally, cocaine can cause metabolic acidosis, further disrupting electrolyte balance 1. Recovery requires addressing both the immediate electrolyte abnormalities and the underlying substance use and eating disorders through comprehensive treatment programs. These programs should include medical supervision, psychological support, and behavioral interventions to ensure a holistic approach to recovery.

From the Research

Cocaine Use and Electrolyte Imbalance

  • Cocaine abuse can lead to various medical complications, including cardiovascular issues, seizures, and gastrointestinal problems 2
  • The use of cocaine can cause intense vasoconstriction, potentially damaging all organ systems, including the kidneys, which can lead to electrolyte imbalances 3
  • Hypokalemia (low potassium levels) is a potential complication of cocaine abuse, which can cause muscle weakness, arrhythmias, and other symptoms 4
  • There is limited research specifically focusing on the relationship between cocaine use and purging electrolytes, but it is known that cocaine can cause dehydration and electrolyte imbalances due to its diuretic effects and increased sweat production 5, 2
  • Treatment of cocaine-related toxicities is generally supportive and based on the affected organ system 2
  • Medications such as benzodiazepines, calcium channel blockers, and alpha-adrenoceptor blocking drugs may be used to manage symptoms of cocaine toxicity, including hypertension and tachycardia 5
  • Electrolyte replacement therapy may be necessary to manage hypokalemia and other electrolyte imbalances caused by cocaine use 4
  • It is essential to monitor patients with cocaine toxicity closely, as they may be at risk for severe complications, including organ failure 3
