The specific RX for SIBO is v.expensive and when I brought the cost to the attention of my NP, she found another antibiotic that she prescribed instead. I used it for, I think 10 days or so, during which time and the following 2 weeks, I felt good. After that time, symptoms came back and I asked for a refill. She would not refill it, not a long term solution?, and then she left the practice so I’m just now rediscovering my SIBO diagnosis and trying some naturopathic solutions. Not clear of symptoms yet.
