xifaxin migraines?

My daughter had bad headaches and a fuzzy head feeling on xifaxin.

Loved this drug. Can't say that about too many.Sorry your having problems on it.

The migraines have gone away and now it just dizziness, nausea, and an increase in runs to the bathroom. The good news is that the pain I had been living with for so many months is gone! The side effects are worth it.

Xifaxin is not really systemically absorbed into the bloodstream so the only side effects it should produce are gastrointestinal, e.g. diarhhea, cramps. If someone is getting headaches I don't understand how xifaxin would be the cause as it is very poorly absorbed, although maybe the minimal amount that is absorbed is enough to do it. What I have read about it is that the side effects are usually exclusively gastrointestinal.

I would be very careful about claiming causation of any systemic side effect outside of the intestinal tract on xifaxin.

I had never read of headaches being a side effect either so I was surprised to experience it. It must have been a coincidence because the headaches stopped after two days and I was on the Xifaxin for two weeks.

The best news is that it seems to have worked! I am out of pain for the first time since shortly after Thanksgiving. Time to train for another half marathon!
