You're exactly right, Trish!! Why in the he77 the docs don't tell patients that is beyond me...
My late FIL got it bad...ended up in the hospital/nursing home for a few months off and on. Once we began giving him milk with acidophilus in it, the side effects cleared up. The docs didn't recommend it--we found out by researching on line. DH would stop off at the nursing home every day to make him drink it.

The antibiotic that often brings it on kills all of the good gut bacteria. It's a very serious disorder!
Doydie, don't use the toilet after him, and clean it thoroughly with antiseptic wipes!!
You might want to drink a probiotic as well...
