Cancer Related Fatigue can linger even several months after treatment is completed. If you are already doing the things you mention below, and if you have no other medical problems esp. high blood pressure; we give our patients psychostimulant drugs (example Provigil and Ritalin) This is assuming that patients have no reversible problems that's causing fatigue. Non pharmacologic interventions are; exercise, sleep hygiene, relaxation and self hypnosis, is with pain- accupuncture, etc. If you are a patient at MDAnderson and want a full evaluation from our clinic, just ask you attending to write a referral to the fatigue clinic.
