Hi there! Welcome to the Lyme Support Group!

Here is some information on herxing:

The Herxheimer reaction (also known as Jarisch-Herxheimer or Herx) occurs when large quantities of toxins are released into the body as bacteria (typically Spirochetal bacteria) die, due to antibiotic treatment.

Typically the death of these bacteria and the associated release of endotoxins occurs faster than the body can remove the toxins via the natural detoxification process performed by the kidneys and liver. It is manifested by fever, chills, headache, myalgia (muscle pain), and exacerbation of skin lesions. Duration in Lyme can take months or years. The intensity of the reaction reflects the intensity of inflammation present.

Overview:

In general terms, it is described as a temporary increase of symptoms when antibiotics are administered. What is known or speculated about Lyme disease herxheimers are based heavily on the reactions seen in syphilis. This is due to the fact both diseases are caused by a bacteria known as a spirochete, the former being Treponema pallidum, the latter Borrelia burgdoferi (B.b). However the herxheimer reactions in Lyme disease are not identical to those seen in syphilis, especially in terms of timing, frequency and duration as noted below.

In Lyme disease it is thought that the cause of herxheimers are the result of endotoxin release, that is toxin(s) within the spirochete that are released as the B.b are killed or broken down. This may be a result of the toxin(s) itself or the body's immune response to such.

Symptoms:

As mentioned, the general description is a temporary increase in symptoms, but also included is the development of new ones. More specifically the most common events include: increased joint or muscle pain, headaches, chills, fever (usually low grade), drop in blood pressure, hives and rash. A multitude of other symptoms have been described.

Worth noting is that hives and rash are sometimes mistaken for an allergic reaction. It is up to one's physician to determine this, but with close observation and the use of medications such as Benedryl often prevents stopping antibiotics prematurely. In more severe cases of J-H a reduction of the dosage or temporarily cessation of the treatment is an alternative.

Timing, Frequency and Duration:

This is individualistic and Herxheimer can occur within days to weeks after the onset of antibiotic therapy. In some patients they occur only once or twice (if at all) and with others continue throughout the course of treatment, usually lessening in severity. They can occur and are more often described in cycles (example: every 4 weeks) and have been reported to last from days to weeks.

It can be very beneficial to document these exacerbations. Some physicians use this as a guideline for treatment. Further it may help differentiate herxheimers from the normal symptoms or progression of Lyme disease.

Treatment:

Herxheimer reactions can be very difficult on patients and affect compliance with therapy so supportive measures should be sought or utilized to lessen discomfort if needed. The use of aspirin, NSAIDs (non steroidal anti inflammatory drugs), pain medication, muscle relaxers, hot baths or others remedies can be appropriate. Of note, some have found Benedryl helpful even in the absence of rash or hives.

The good news is that the herxheimer is thought to indicate that the antibiotics are indeed working and that following each worsening may bring about more improvement. However the lack of herxheimer reaction should not cause anxiety if symptoms are improving.

Other considerations:

Something often overlooked but can present with similar symptoms as a herxheimer is Candida (yeast) infection. Treatment with acidophilus and if needed prescription medications such as Nystatin or Diflucan can be utilized.

Tamtic, Something else that may help you, since the symptoms are so "individual," from talking to people here on the forum, and from my own experience, it seems that the actual symptoms appear to be whatever your actual main LD symptoms are. It seems that they seem to worsen when you have a Herx, and it seems that the Herx is an exacerbation of your worst symptoms. For me, I've noticed that and it seems that many other members have told me the same thing...That may help you to understand it a little bit better. That's why not everyone's symptoms are the same, as we all have different symptoms of LD, though we're similar! Smile Hope that will help some, too!

*hugs*

I want to thank everyone who has been replying to my questions. I have learned a lot from the people on this page along with other lyme web pages. I want to make sure that I am an informed patient who is not going to take what one doctor as "The only possible answer".

Thanks
