Rheumatoid Arthritis
"I have used Enbrel for more than a year to treat Rheumatoid Arthritis.  I have had no adverse reactions to the injections and have been pain-free/symptom-free since the 3rd day after my first injection. I have used both the pre-filled syringe and the pen, both are fairly easy to use, but the pen is by far the easiest between the two."
