RT Journal A1 Teitelbaum JE, Bird B, Weiss A, Gould L T1 LOw-dose hydrocortisone for chronic fatigue syndrome JF JAMA JO JAMA YR 1999 FD May 26 VO 281 IS 20 SP 1887 OP 1889 DO 10-1001/pubs.JAMA-ISSN-0098-7484-281-20-jbk0526 UL http://dx.doi.org/10-1001/pubs.JAMA-ISSN-0098-7484-281-20-jbk0526 AB Our previously published pilot study2 and the work of Jefferies3- 4 suggests that using low-dose hydrocortisone (4 mg of hydrocortisone ≈ 1 mg of prednisone) in CFS at dosages of 7.5 to 20 mg/d is safe and effective. These low dosages have not caused the adrenal suppression3- 4 seen with the higher dosages (25-35 mg/d) used by McKenzie et al. They are also less likely to aggravate the already severe disruption of deep sleep present in CFS patients, as was seen in the study by McKenzie et al (P=.02 vs placebo).
