Rifampin for Lyme Disease: When Doxycycline Isn’t Enough
DOXYCYCLINE—
NOT ENOUGH?
WHEN RIFAMPIN MAY HELP
What happens when doxycycline isn’t enough to treat Lyme disease?
Doxycycline has long been a first-line treatment for Lyme disease due to its effectiveness against both Borrelia burgdorferi and certain co-infections.
Quick Answer: Rifampin may be considered in select Lyme disease cases—particularly when patients do not respond to doxycycline or when co-infections such as Bartonella are suspected.
Clinical Insight: Lyme disease and associated co-infections can vary significantly between patients. A lack of response to doxycycline may suggest the need to consider alternative or additional treatment strategies.
Why Doxycycline Is Often Used First
Doxycycline is commonly used because it is active against Lyme disease and co-infections such as Ehrlichia and Anaplasmosis.
These infections are often transmitted by the same ticks and can complicate the clinical picture.
When Rifampin May Be Considered
Some patients are unable to tolerate doxycycline due to side effects.
Others may not improve despite appropriate treatment.
In these cases, rifampin may be considered as part of an alternative approach.
This is particularly relevant when co-infections such as Bartonella are suspected, as these infections may not respond fully to doxycycline alone.
Individualized Treatment Matters
Lyme disease treatment is highly individualized.
Each patient responds differently, and treatment decisions must take into account the full clinical picture—including symptoms, co-infections, and response to prior therapy.
This variability is one reason why some patients require adjustments in treatment over time.

Clinical Perspective
Over time, treatment strategies for Lyme disease have evolved as clinicians have gained experience managing complex cases.
When patients do not respond as expected, it may be necessary to reconsider the diagnosis, evaluate for co-infections, or adjust the treatment plan.
The goal is to provide care that is tailored to the individual patient rather than relying on a single standardized approach.

Would you be willing to prescribe Dapsone, Doxycycline, and Rifampin together?
Not at this time. Sorry.
does rifampin deal with all forms of borrelia??- persisters forms, biofilm, or only in the blood stream?
Rifampin has been used for Ehrlichia, Anaplasmosis, and Bartonella but not for Lyme disease.
Every patient is different. I have patients who overlook other tick borne infections.
I always wondered if Rifampin was used in Lymes because of the possibility that it would penetrate the protective coating of Borrelia. I have had several cases of Lymes and Doxycyline is deadly to my gut. I wonder if Cefuroxime in combination with Rifampin would be effective.
It is unclear if Rifampin works for Lyme. I have found Zithromax helpful some some. I have also found treatment for Babesia helpful.
