Cimzia
"I initially took Cimzia as part of a clinical trial.  During the trial, we received a full dose (400 mg) every 2 weeks but, once it was available on the market, the dose was only 400 mg every 4 weeks (or 200 mg every 2 weeks).  The medicine wore off before the 4 weeks was up, so I switched to Humira, which worked much better.  Now that I've had rare side effects to Humira (and already failed Remicade), I've had to switch back to Cimzia.  It is only working for about a week and a half of the four weeks (at 400 mg).  I hope to find another alternative, as this isn't worth it."
