title: Herbal weight-loss supplement misadventures per a regional poison center.
abstract: BACKGROUND
  Many herbal supplements used for weight loss contain stimulants. The poison control center has noted an increase in reports of adverse events with intentional and unintentional ingestion of herbal weight-loss supplements.
  
  
  OBJECTIVE
  To identify characteristics of the callers (eg, demographic properties, underlying type of ingestion) and, from this information, determine populations at increased risk for adverse events secondary to intentional and unintentional herbal weight-loss supplement ingestion.
  
  
  METHODS
  Demographic information such as patient weight, age, gender, and medical history was recorded from ingestions reported to the Central Ohio Poison Control Center (COPC) in 2000. Ingredients, concurrent medications, ingestion and treatment site, clinical presentation, and therapies received were documented. Type of ingestion, acuity, clinical presentation, and treatment site were used to identify patients at increased risk of adverse events secondary to herbal supplement ingestion.
  
  
  RESULTS
  Eighty calls were recorded in 2000 (49 females involved). Underlying reasons for ingestion differed between males and females (p = 0.025). Twenty-five percent of the intentional ingestions and 51% of the unintentional ingestions occurred in males. Reported symptoms differed with the underlying reason for ingestion (p < or = 0.001) and were more common in intentional ingestions (80%). Symptoms were reported more often with unknown or higher-than-recommended doses (78%); however, 70% (n = 10) of subjects ingesting the recommended dose reported at least one symptom (p = 0.15).
  
  
  CONCLUSIONS
  Intentional and unintentional ingestions of herbal supplements for weight loss vary with age and gender. The significant presence of symptoms in nonabusers requires more study to assess overall safety and potential toxicity of agents such as Stacker 2. Patients who abuse or misuse herbal weight-loss supplements are generally women, who may seek medical treatment more often.
