Hi Lovelabs. I am curious why your doctor is pulsing the Mepron and Zithromax this way. These meds treat the co-infection Babesiosis, but Zithromax can also be effective for Lyme. What doses of each are you taking?
Many people who have Babesiosis herx every three weeks. I think it will be difficult to tell if you are herxing or having an increase in symptoms until you have documented your symptoms for several weeks.
You may want to talk with your doctor about this to see if this is what he/she expected to happen.
