Psoriatic Arthritis
"I took enbrel for about 8 yrs with great satisfaction and little side effects.Then it lost its effectiveness and I changed to Humira with even better results.Now after 7 more years it appears its effectiveness is starting to wane .I&#039;m considering going back to enbrel and trying it again hopefully with comparable results as  the first time. good luck to all and I hoped this helped someone."
