Oh yes! That is how I contracted C-diff! It WAS Clindamycin that was prescribed by my dentist back in February of this year. I almost died and that is not an exaggeration. I was so so sick. Then I cried when they told me I had to take another antibiotic to fight the C-diff. It was Vancomycin and it did work, thank God above. But now I have the SAME dental problem that I had back in February, except it is worse now. So back on the antibiotic before surgery. Would you please let me know about the tetnus shot? I would like to be safe also. It is important we question everything. Best wishes to you. Jacque
