systemic lupus erythematosus
"I was diagnosed with Discoid lupus in 2009 and I began using Plaquenil once I stopped breastfeeding. Initially, the only difference I noticed was my hair stopped falling out. After taking Plaquenil for a less than a year my face and neck started turning black. My dermatologist is convinced that Plaquenil is the culprit and just recently confirmed it. Between my rheumatologist and dermatologist they're trying to find the right medicine that will work. I've been using bleaching creams for about 9 months and they haven't worked well. I tried to come off Plaquenil but I experience bad headaches and hair loss."
