Sulfasalazine
"Been a psoriatic arthritis sufferer these last twenty years. My flare ups are dreadful. After taking them for just two weeks symptoms are abated; it really works for me despite convincing my new GP I knew what I was on about! Methotrexate was awful. No side effects with SULFASALAZINE with me. After three months no pain at all....but one needs to drink lots of water. I've had periods on and off this drug, all due to flare ups..."
