NCT01793415

Brief Summary

Chronic fatigue syndrome (CFS) is a devastating and complex disorder. People with CFS experience overwhelming fatigue and a host of other symptoms that are not improved by bed rest. Interestingly, many of the symptoms experienced by people with CFS are identical to symptoms caused by long-term low-level exposure to mercury, which is called micromercurialism. This study will examine if the mercury binding substance IodoCarb(r) can improve the health of patients with CFS.

Outcome Measures

Primary Outcomes (1)

  • Quality of life questionnaire score

    The QoL score during the last (fourth) treatment week is compared to the QoL score during the control week just prior to the treatment period. Results from patients receiving active substance will be compared to patients who received placebo.

    The QoL score during the last (fourth) treatment week is compared to the QoL score during the control week just prior to the treatment period.

Secondary Outcomes (2)

  • Use of psychotropic drugs

    The intake of psychotropic drugs during the last (fourth) treatment week is compared to the intake during the control week just prior to the treatment period.

  • Physical activity measured by a pedometer

    The physical activity of patients during the last (fourth) treatment week is compared to the physical activity during the control week just prior to the treatment period.
