My understanding is the the worrisome components of the GI Cocktail (viscous lido and donnatal) are marginally effective at best anyway. I just give the Mylanta or Maalox and skip the others. I actually try to do that for everyone regardless of pregnancy although I do get a few who want "the green stuff" or they won't get the full placebonated effect. It's similar to the po motrin vs. IV toradol issue.
