ABSTRACT
Modafinil has shown benefits in fatigue-related
disorders such as multiple sclerosis and various forms of neurological
fatigue.1,2
We report the successful use of modafinil for fibromyalgia (FM)
fatigue in 4 patients in an open study with naturalistic on-off experiences. A
rheumatologist and another physician confirmed each diagnosis of FM.
FM affects 2% of the population and is
characterized by chronic musculoskeletal pain (especially at characteristic
soft-tissue trigger sites); severe fatigue, typically lasting >24 h with
minimal activity; nonrestorative sleep; and mood abnormalities.3–5 The
American College of Rheumatology adds the criterion of widespread pain for 3
months with tenderness in at least 11 of 18 specific trigger-point sites. 6
We excluded 2 patients for comorbid secondary
major depression (MD) until they went into full remission on their
antidepressants, confirmed by two MD research scales, to remove the variable
of modafinil antidepressant augmentation.
7,8
All patients had physical exams and laboratory
testing excluding Lyme disease, Ehrlichia equi and E. chaffeensis, Babesia
microti, rheumatoid or spinal arthritis, major sleep disorders, and abnormal
cervical and brain MRIs.
After an average 18 months of medical care,
they found minimal relief. None could stay awake 16 hours on 3 consecutive
days, shop routinely, provide basic childcare, drive over an hour per day,
balance a checkbook, maintain a 30-hour work week, or cook routinely. Patient
expectations for relief from this trial were very low because of past
failures.
Two FM patients reported some beneficial
effects of depression on day one at 100 mg q A.M., which were nevertheless
incomplete. Weekly dose adjustments upward in 50-mg increments and the
addition of an afternoon dose met with reports of highly significant benefit
by all patients. After titration adjustments were finalized over 3 weeks, all
reported a sustained increase in functional capacity. Global Assessment of
Functioning average improvement was a change from 55 to 70; that is, from
moderate impairment to minimal impairment.
All patients had a strong desire to continue
their treatment because they now reported being "functional," able
to work or to care for their children. Fatigue improved; all patients reported
highly significant improvement in alertness and a reduced need for disruptive
naps. They received unsolicited comments about their improvement from their
children, spouses, employers, or parents, who were unaware of the modafinil
trial. Benefits persisted over 3 continuous months at the same dose.
Alertness benefits were lost if a breakfast modafinil
dose was skipped. Benefits returned quickly the following day if modafinil
was restarted. Each patient missed at least 2 days of medication
because of forgotten doses or a lost prescription. They reported a full return
of fatigue and impairment that day. These mishaps represent naturalistic
"on-off" experiments, supporting the immediate efficacy of modafinil.
This immediate effect contrasts with our clinical expectations of gradual
benefits.
The mean dose was 250 mg per day with a range
of 150 to 300 mg. Patients took a dose of 150–200 mg in the morning, and
half of them took an extra 50 mg or 100 mg in the early afternoon. One patient
reported slight anxiety during week one, which resolved with a 50-mg dose
reduction. We experienced inconclusive results in 3 patients, not included in
our report, who dropped out or were lost to follow-up for reasons such as
relocation.
The fatigue of FM causes marked impairment and
has no definitive single treatment. Modafinil is a potential treatment option
worthy of larger clinical trials.
