Although I was diagnosed SLE, my illness was originally triggered right after I had taken
ONE Tetracycline pill. Call it a drug-induced flare, call it a coincidence, I don't know. What I DO know is that I have never touched Tetracycline since, and it is on all my medical charts that I cannot take anything in the same family as Tetracycline. The sysmptoms I had were mainly very painful, swollen, stiff joints.
