    Plaquenil allergic reaction -rash. What now? - NeuroTalk Support Groups Plaquenil takes several weeks to build up in the system. So this may be why your reaction didn't occur immediately. Likewise, the half life is 60-90 days, so your rash may be slow to dissipate. Hopefully because you were on it such a short time and may not have even accumulated to a full blood level, it will leave your system a little faster.

    Plaquenil Drug and Medication User Reviews on RxList I also have osteoarthritis. I started on Plaquenil in 2015 200 mg then increased to 400 mg after 3 months. It took many months for the ulcer like spots to go away but the drug works. In January 2018, I no longer had insurance so I dropped back down to 200 mg. It also took away most of my OA pain in my knees and hands.
