To treat the irregularities, medications called immune regulators are used. Availability is limited to PWCs with access to a clinical site and the financial resources to cover the cost. Symptom improvement has been inconsistent with this therapy as well, and further research is underway. Gastrointestinal Disorders Many PWCs experience problems with their digestive tract, particularly with irritable bowel syndrome. Symptoms are worsened by stress.
Drug therapy includes antispasmodics, antidiarrheal, and anti-anxiety medications.

The doctor and pharmacist need to be informed of every drug the PWC is taking - even a daily multivitamin or nutritional supplement. There is always the potential for an unpleasant interaction when drugs are mixed. Intravenous immunoglobulin is ineffective in the treatment of patients with chronic fatigue syndrome.
