....about ABX- there is one abx "family" that can cause tendon issues. I forget which ones. Might be the Levoquin types (spelling) Its common knowledge, you can google it. Most regular ABX doxy, cipro ect does not.
The abx family is the fluoroquinolones - levaquin, ciprofloxacin are two in that class.
I haven't read anything on minocycline or clindamycin causing that.
You could call the pharmacist and check.
The fluoroquinolones have the black box warning label for this reason.
