What is a Herx?

A Jarisch-Herxheimer Reaction (often called a Herx for short) is the reaction that your body gets when there is a spike in die offs from the Lyme disease and associated co-infection bacteria. It is sometimes seen as a good sign (that the medication is working), however severe Herxes can be dangerous (causing brain and organ damaged) and so need to be managed carefully.  As such, the LDAA recommends you work with an experienced Lyme Disease doctor to guide your treatment, rather than self treating from information that you have sourced off the internet.

Managing a Herx

It is important that a herx is managed in conjunction with a Lyme disease physician, however some patients find it useful to gain insights and understanding from other patients about their herx reactions. The following patient-authored account provides an insight into one patient's herx.

Further resources

Some Lyme practitioners recommend that their patients drink the following drink to ease herx reactions (it is better to limit herxes by not being too aggressive with treatment, but if you do get a mild herx, this may help to ease it). Please remember to distinguish between ordinary Alka Seltzer and Alka Selzter Gold. Alka Selzter Gold must be purchased from overseas.

Alka Seltzer Gold can be purchased internationally:

  • Many Lyme patients purchase Alka Seltzer Gold from VitaCost which also offers free international shipping to Australia.
  • Alternatively, you can purchase Alka Selzter Gold from iHerb. Remember though to use the iHerb Gift Code (NGM198) which provides a small donation from your purchase to the LDAA.

Alternatively, if you are unable to get Alka Seltzer Gold, then sometimes lemon juice squeezed into water can give some relief.
