Does Rifampin cause you to have to adjust thyroid meds?

Yes. I did have to have tsh and t4 labs every 6 weeks to re-calibrate synthroid dosage. My pcp was forewarned when i went on rifampin. I am off rifampin 3 months now. Just beginning to get normal tsh t4 levels again.

Thanks — how far did your TSH go up—a lot or just a small amount?
Did it keep going up over and over again the whole time or just one time?
I am super sensitive to thyroid changes. My ID doc said he hasn’t had anyone have to raise their dosage on Rifampin. But he may not have been privy to it if they dealt with their pcp.
