Then I understand that minocycline will also be affected by these two antibiotics .... it is also synthesized in the liver.
Apparently it's just doxy...from what I've read.
I plugged them into the Drug Interaction checker I use:
Applies to: doxycycline, rifampin
Using rifAMPin together with doxycycline may decrease the effects of doxycycline. Contact your doctor if your condition changes or if your infection worsens. If your doctor does prescribe these medications together, you may need a dose adjustment or special test to safely use both medications. It is important to tell your doctor about
all other medications you use, including vitamins and herbs.
Interactions between your drugs
No results found in our database - however, this does not necessarily mean no interactions exist. Always consult with your doctor or pharmacist.
LLMD MR mentions the interaction doxy/rifampin in his Treatlyme book.
