I'm very afraid of getting sick while on Enbrel. I wash my hands all the time, I quit biting my fingernails, and stay away from sick people. If someone were to come to work sick I would let them have an earful, and then stay away from them. I even time my shot so I'm in it's 60 hour half-life time when I'm not going to be around people. I am VERY lucky in that I get to work completely from home as of 10/08, so I take the shot on Monday nights.
I got sick all the time while on MTX and Prednisone. Prednisone is horrible. It is a miracle for about a month or two, and then you can forget it.
My insurance will only pay for Enbrel if I get it through one of three pharmacies in the whole country. The insurance company purchases the drug directly from the manufacturer and distributes it only through these three places. They will not pay anything towards the cost if you get Enbrel anywhere else. But - nobody told me any of this. Took me weeks to figure it out, and several more weeks to actually get the process going. Thank God they pay for it. When I first went to the pharmacy they wanted $2k!
If your insurance won't pay, try to change insurance companies! Enbrel is still very very new so hopefully as more and more people take it the cost will come down.
