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'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."
