I agree. It should not be used. And apparently, it is KNOWN to cause trouble with patients. Even my brother-in-law, retired MD, casually says the problems are quite prevalent in patients that have used Clindamycin. My question is, WHY do they keep using it?! I have been dealing with the aftermath since February of this year, after taking Clindamycin prescribed by my dentist. I was deathly ill and have now gratefully recovered from the C-diff but not from what it did to me. I took this drug without question because I trusted. Never again. I am fortunate that one round of Vanco got rid of the C-diff (I pray that's accurate), but I have not been the same since and I was told there is no knowing how long it will take for the body to heal. Everyone is different.
