I love my Humira, too. I use it for Ankylosing Spondylitis and had been on a two-week interval but when I was pregnant and breastfeeding, my doctor and I agreed to an "as-needed" basis, since the Humira kicked in pretty quickly when I used it. I am fortunate (supposedly) to be keenly aware of when things are starting to brew disease-wise, so for the past six years, it had been going well.
I guess I got a little too lax (managing to get by with one injection every two to three months) because my Uveitis flared suddenly about six weeks ago with no warning. It's an auto-immune eye disease that goes hand-in-hand with Ankylosing Spondylitis. The eye specialist wanted me to get back to a regular schedule so I didn't risk my vision, so now I'm at about every three weeks. Of course, it could all change again tomorrow, and if that happens, I'll deal with it then.
I'm so very glad to hear that you have some help managing the cost. I'm fortunate to have a low co-pay for it, but what if I didn't?! It seems inhumane to me for some people not to have access to it due to cost since it works so well for so many. It's good to know that there are resources available so people don't have to suffer needlessly.
Keep us posted on how you're doing. :-)
