When I start antibiotics, I double my probioc dose for the duration of he abx. I take Imodium three times a day, also for the duration. The day after I finish the abx, start using Hydrocotisone enemas nightly for about
five night, then every other night for about
three nights. I also take Diflucan every three days for three doses after the abx, because they give me yeast issues.
I still get D, but much less serious and it's over within a few days of finishing the abx instead of a month or more later.
