rash on spine.. possible from humira???

[hmmm]

i just recently started on humira (pen injections) two weeks ago tomarrow will be my second dose. im also taking methotrexate, plaquenil, prednisone, acyclovir, and percocet, but last week i started to get what i thought was pimples on my back. but its not its red bumps and if you just glance i guess they look like pimples but not really its a rash, the bumps are bright red, but don't itch and they are only on my spine from about my shoulder blades down.
im basically wondering if it could be something from the humira and if i should wait to take my dose tomarrow and go speak with my rheumatologist
i never got a rash at the injection site nor did i have any pain or tenderness
im just asking because ive never see a rash solely on the spine like this
thanx
hmmm

Hello,

Allergic reaction in the form of skin rash is a known side effect of the Humira (a Tumor Necrosis Factor (TNF) blocker).
This is a considerable side effect that you should inform your doctor with before receiving the second dose.

A rash with this particular distribution makes exclusion f viral reactivation (herpes Zoster) is essential too even if you are under antiviral therapy. Being on immunosuppressive medications, make you at risk of virus reactivation that can also present in atypical form and with no itching or numbness.

These are the two most important causes (in my openion) to be excluded before your next dose and before considering any other causes.

I would advise you to inform your doctor and to follow up with him.
Please keep updated.
Best regards.
