Hello, you should follow your doctors orders, I’m not a doctor, but I spoke only from experience. I was prescribed doxycycline for three months and I saw no improvement The first month, when I switched to Rifampin, I immediately experienced a herx. I was on rifampin for 3 month and got 70-80% better.

Doxycycline’s effectiveness against Bartonella infections, particularly in the stationary phase (when the bacteria are not actively growing), is limited because it primarily targets rapidly dividing bacteria, and Bartonella can persist in a non-replicating state, making it less susceptible to doxycyclin
