I am a double board certified US doctor and I can help you with this.
The first question is why was she on rifampin.
This is only used for certain illnesses, and she can not just stop treatment for those illnesses.
That is concerning.
Rifampin is out of the system in 18 hours, approximately.
Since the last dose.
If there are symptoms much beyond that, then something else is amiss.
This is not a self help situation, and any such situation should be brought to her doctor's attention immediately.
Or answering service
Or urgent care.
