Effects of FENNEL SEEDS on antibiotic XIFAXAN.

Resolved Question:

Fennel Seeds and Xifaxan (Rifaximin)

My question pertains to the simultaneous usage of fennel seeds and the antibiotic Xifaxan. Some background: I have been suffering from relatively problematic bloating (makes me look about 4 months pregnant as a male) for around the past 2 years. I have had many tests done and the doctors have basically settled on IBS. In between my last test and the beginning of my antibiotic treatment I began taking 1/2 a teaspoon of Fennel Seeds after each meal as a sort of desperate attempt at homeopathic treatment. I began taking the antibiotics, but also continued with the fennel seeds to try to help with the bloating. However, I read today that fennel was shown in a study to interact with Ciprofloxacin (A Fluoroquinolone Antibiotic); specifically, that fennel may inhibit the absorption of the antibiotic. According to a Wikipedia page Xifaxan is not a Fluoroquinolone Antibiotic, but I am still worried I may have ruined two weeks of treatment by using fennel at the same time. Any professional insight would be greatly appreciated,

Thank You.

Hello.
Thanks for posting your query at DoctorSpring.com
I am Dr.R.K and I am pleased to assist you.
No , Fennel seeds do not interact with rifaximin.
In fact, the interaction between fennel seeds and ciprofloxacin itself is not a confirmed one.
So there is no need to worry that you have taken fennel seeds along with rifaximin and that fennel seeds would have affected the absorption of rifaximin.
I hope that answers your question.
Let me know if I can assist you further.
Regards,
Dr.R.K.
