Mark - oh my gosh, your PCP brought this up as an alternative!! That is awesome news. This has traditionally been a treatment that the docs reject wholeheartedly, despite overwhelming evidence to the contrary. It's nice to see the tide turning. This is the RedHill combo, which is probably the best. In the US they substitute levofloxacin for the clofaz, since it's easier to get, but it may have more side effects. I'm was on the US formula and my Crohn's went away completely. I had issues with the levo, dropped it, added LDN and have been fine for 16 months. Check out this site for all the research and FAQs: TheCrohnsInfection.org. You're welcome to join our private Facebook too and ask others who have tried this combo about it.
You'll feel gross at first, especially if you start it full strength, but then hopefully you'll start getting better and better over 3-4 months. Also, you can get a test through John Aitken's lab to see if you have the mycobacteria this is supposed to treat. Most Crohn's patients are positive. Good luck, and feel free to contact me since I've been through this. Encouraging that your doc is recommending it. Finally!!!
