Ustekinumab
"After 6 years on Enbrel, it finally stopped working and I started on Stelara this past July 2013. Excellent results clearing tough, thick-skinned body areas like elbows and knees within 1 to 1.5 months and I'm very pleased. Somewhat perplexing while on Stelara are short cycles of psoriasis turning up and then disappearing from thin-skinned areas like scalp while the bigger problem body areas remain clear. I never had scalp psoriasis while on Enbrel, but I'd still choose Stelara overall for faster, better overall clearing."
