Not sure what your doctor told you, however Humira can take anywhere from 3-6 weeks after the first injection to start taking effect.
I take Humira for Ankylosing Spondylitis, and have been taking it every two weeks since October 2010. For me, it was about 2.5 weeks after first injection to start noticing little differences. After my second shot at the 4-5 week mark many of my A.S. symptoms had dramatically subsided.
It was just after my third shot, approximately six weeks after I started Humira that I felt "normal." I've been taking it every two weeks since and all my A.S. symptoms are under control.
I also have a good friend who's wife has Crohn's. I'd read all the product documentation which stated it can also be an effective treatment for Crohn's and told he and his wife about it. Her Chron's disease is now well under control, thanks to Humira.
The biologic drugs are really life changing, however they don't always work for everyone. I know other folks who have tried Humira and it didn't work for them, whereas another biologic such as Sympani for example, did work.
How long has your daughter been on Humira? Have other biologics been tried or discussed?
We are on our third month of Humira... no improvement what so ever. Doc says to give it six months...
