Hi all, this is my first post on this site. I have had Rheumatoid Arthritis for 13 years, I am currently 45, turn 46 shortly. I have been on many biologics, basically since they came out, including Remicade, Enbrel, Humira, and Orencia. After having many infections in a short amount of time (approx. 2 months), I was on and off of my Humira. During this period, I woke up with extreme dizziness, 24/7, do not even have to move my head or open my eyes. This lasted for 8 1/2 months! I quit my Humira all together, as we had to look at this as a possible reason for my central vertigo. It has been proven through inner ear testing that it is central. I also had an MRI of brain done which came back normal. My RA and Osteoporosis became very bad after being off the biologics for about a year due to the horrible vertigo. It became so bad that I finally decided recently to try Orencia. My vertigo had subsided, and it was about 85% gone for about 2 1/2 months, then returned after only a month on Orencia, and is exactly as it was before, 24/7, very miserable, in which my head perceives it is in constant motion. I have a rocking sensation in my head at all times, worse when laying down, feel very drugged, very off balance. I have to believe this is due to these biologics!! Has anyone else experienced anything like this with biologics or other meds for other chronic illnesses? I would so appreciate your comments! I have been to several neurologists who cannot grasp this, so I have been left to suffer immensely...Thanks for your time!
