Acne
"My daughter started taking minocycline 3 years ago at 14 for her acne. It worked well enough until she began having severe muscle and joint pain. We had no reason to blame the minocycline. A rheumatologist diagnosed drug-induced lupus. Even after stopping the minocycline, and starting Naproxen for the inflammation , (so bad that she could barely sit down, raise her arms above her head, or even walk) she got worse. An MRI with injected dye revealed severe muscle inflammation, and the Dr has put her on prednisone 40mg for a month, tapering to 30 and eventually off it. The prednisone helped her within hours. It may take a year for her to recover."
