The Jarisch-Herxheimer reaction (referred to as "Herx" often) is
believed to be a reaction caused by organisms (bacteria) dying off and releasing
toxins into the body faster than the body may comfortably handle it. It was
originally observed in patients with syphilis who received mercury treatment
[*]. 93% of patients with syphilis has Hughes Syndrome,
it is estimated that 92% of CFS patients has Hughes Syndrome.
Most CFIDSers will have moderate to severe herx effects from antibiotics that
will usually have no effects on normal healthy individuals[83% in one R.A.
study, 51.4% in Lyme Disease, 89% with B. recurrentis infection]. The reason for
this may be the diminished blood flow system caused by the thickening of the
blood commonly found with CFIDS patients. Alternatively, "it seemed to occur
when injured or dead bacteria released their products into blood and tissues,
provoking a sudden and exaggerated inflammatory response"[*] - thus the response
may be connected to the specific organism being killed off. Many non-antibiotic
treatments (Hale's breathing, glutathione - whey products ) are reported to also
produce a herx effect -- whether it is bacteria die off or simply toxin release,
the effect is the same: misery!

Intensifiers if on Antibiotics
Onset of Reaction
Depending on illness and antibiotic: from 1-2 hrs to 10 days after
The most common ones include:
- increased joint or muscle pain
- Heavy perspiration and night sweats
- Burning micturition
- Bone pain
- swollen glands
- constipation or diarrhea
- fever (usually low grade)
- hypotension (low blood pressure)
- Itching, hives and rash (sometimes mistaken for an allergic reaction -
this must be an MD's call)
- heart palpitations, elevated heart rate, orthostatic
Tachycardia are reported on http://www.onelist.com/community/cfs_Mycoplasma/
Treatment consists of two approaches: improving the blood flow to clear the
toxins faster (see vascular constriction),
or, neutralizing the toxins (or both)
- Probenecid (Dr. Jadin [*])
- Benadryl (antihistamine)
- Therma-Flu or equivalent
- Aspirin (Bromelain may increase it!)
- Meptazinol [*, *]
- Increase in blood thinning supplements
- Lemon/Olive Oil drink (may be done with water or Grape Juice)
- 2 Tbsp Lemon Juice (Organic) or 1/2 lemon rind)
- 1 Tbsp cold pressed Extra Virgin Olive Oil Water or juice ... stir
- Concord Grape Juice with flavoids (widens blood vessels)
- NSAIDs (non-steroidal anti-inflammatory drugs),
- pain medication (see ibuprofen risks..)
- muscle relaxers,
- hot baths / hot tub
- steam (dry or hot) sauna
- a saltz bath: add 1 cup salt, 1 cup soda, 1 cup epsom salts, 1 cup aloe
vera, to a
- hot bath, remain in and keep hot for about 1-1/2 hours all the while
- about 2 quarts of warm water.
- Hale's breathing
- Control panic attacks, anxiety and worry (they constrict the blood
vessels, worsening the effect).
Differentiating between a Herxheimer, a flare and an allergic reaction to
"Laboratory tests can help differentiate between a worsening of disease (RA
flare), a Herxheimer reaction to microbial toxins, and an allergic reaction to
- WBC will elevate in a Herxheimer and lower in a flare.
- A Herxheimer will also exhibit a coincidental elevation of SED rate, gamma
globulin and total globulin ,and a fall in serum albumin and hematocrit. Patients who exhibit this flare
reaction accompanied by anemia, depression of serum albumin, elevated total
globulin and gamma globulin are probably reflecting a more intense reaction
pattern to anti-L substances than in hematologically mild cases.
- A marked increase in eosinophils (for instance about 30%) is an indication
of an allergic reaction to the drug."
