Someone here will inevitably say "I took Cipro et.al just fine".A lot of my childhood was spent in hospitals, and I've had a variety of antibiotics over the years. And anesthetics, I've become quite the connoisseur. I'm not allergic to anything, I've never had a reaction of any kind to any drug. Not even allergic to any foods. Bring on the shrimp and peanuts!
I was recently given Cipro. My entire back broke out in a rash. Not a devastating side effect, but after a lifetime of a variety of drugs of all sorts without any but the desired effect, it sure made me go "WTF? You sure this shit's safe?"
