Yes, I am taking both Enbrel and Iso.
I only had to take iso one month before I started enbrel. Studies have shown that as long as ISO is treated prior to and concurrently with biologics, turbercleosis typically does not re-emerge, and if it does, you simply need to stop taking the biologic.
Three months in on Iso and one on Enbrel, and havn't felt this good in YEARS.
