Hi Triplet Momma!
Welcome to our community!! I'm so glad you found us!
I don't know enough about
the abx to help, but I edited your post so I could put a title on this thread that would (hopefully) get people's attention that have dealt with this.
According to this list:
www.glutenfreedrugs.com/Glutenlist.htm Clindamycin is gluten free when it's from this manufacturer: Greenstone.
So maybe you can do a special request due to your Celiac's diagnosis for Clindamycin from Greenstone??
