Hi Des,
Here's some good basic information to keep in mind, in the first post in the thread at this link:

Generally speaking, as a group, we have the least problems with antibiotics in the fluoroquinolone group. This group of antibiotics includes Ciprofloxacin, which is probably the most commonly-used of the group. We have found that Cipro not only does not cause D, but it will usually stop any D episode that is already in progress. Unfortunately, a few days after the treatment ends, if D was present before the treatment, it will resume again. The biggest risk with the fluoroquinolones is the increased risk of tendonitis, and in a few cases, torn ligaments, particularly the Achilles tendon, (the greatest risk is for runners). This is normally only a concern with long-term use, but the increased potential is always there, and tendonitis can develop during the use of the antibiotic, or up to several months afterward. This is not a common problem, but we should always keep the risk in mind, and avoiding running and/or stretching exercises during and after the use of such antibiotics should reduce the risk of tendonitis developing, of course.
Another antibiotic that we have had relatively good luck with is Zithromax, (Z-Pak), Azithromycin, etc. Of course, whether or not either of these antibiotics is appropriate, depends on what the treatment is being used for. In general, antibiotics are ineffective for treating a cold, but of course, they can be used to treat secondary infections related to a cold.
If you have problems with frequent colds, or other viruses, taking supplemental vitamin D, (or increasing your dosage rate, if you are already taking it), can really help. Your 25(OH)D level needs to be around 50 ng/mL, or better, to minimize the risk of rhinoviruses and influenza viruses. At your latitude, (Maryland), you probably need to be taking between 5,000 and 6,000 IU of vitamin D3 daily, to keep your resistance up. Most people with an inflammatory bowel disease, (including MC), tend to have a relatively low blood level of vitamin D.
