how much Mercury is in enbrel?

Answer 1

none

read the PDF file which lists ingredients and neither mercury or thimerosol is listed as an ingredient.

In this day and age it would be very foolish for a drug compnay to spend hundreds of millions of dollars developing and getting a new drug to market and then to also include mercury as one of the ingredients. Just would not happen.

Answer 2

for that go on www.yahoo.com or www.fda.gov and see look for the material data sheet for the drug.
on the net.
