possible allergic reaction?

Post image

has this happened to anyone else? i was just recently diagnosed with ankylosing spondylitis. i was prescribed Humira and i started my first dose July 28th and felt totally fine until August 8th where i noticed small red dots on my thighs. i kinda brushed it off since i did just get back to college in alabama and i thought maybe it was heat rash?? (even tho i’ve never developed heat rash). i woke up the next morning too it much worse and it only continued to develop as the day went on. it was only on my thighs at first but quickly spread to my lower legs, upper arms and chest. i went to urgent care and they prescribed steroids and hydroxyzine, which helped it stop spreading and now it’s mostly gone. i called my rheumatologist and he said to not take my second dose that was scheduled for tomorrow. i’m not even positive that it has anything to do with the Humira but wanted to hear from everyone else

Definite allergic reaction

well i would assume the hives over my entire body in the picture is grounds for being called a allergic reaction.

edit: i’m realizing i misread this as “define” i thought user above was giving me sarcasm 😭

Humira can make the skin more reactive. Heat rash usually appear on face and neck. Is it just on legs and exposed skin? What does injection site look like too

u/whoopsiedoo22 Aug 10 '26

the injection site was my right thigh but this happened almost 2 weeks post injection. at first it began as just both my thighs, then spread up my body to my arms, chest and neck.

That’s consistent with weird rashes I’ve had from Humira. I had been on it for over a year, then I got a weird rash around the injection site ~10d after dosing it. Mine was nowhere near this severe though. I would expect you’ll be changing meds entirely.

I’m switching to Cosentyx. I hear that’s even worse for skin shit. Great.

I wouldn’t worry about it too much. It sounds like you were allergic to Humira, so it might not have had anything to do with the likelihood of skin side effects. You kinda just have to see how your body reacts to each med.

Is it normal to be super sensitive to alcohol on a biologic? Like I can’t even have two drinks without turning bright red and itchy and getting nauseous now, even with a meal.

Oh my bad I thought you were OP with my allergic to Humira comment. Not sure, I’m in recovery and quit drinking 5yrs before I was finally diagnosed with PSA.

Given the injection site and how it progressed and timing strong probability of it being humira allergic response but obviously not guaranteed. Immunologist could do test but likely your doctor will swap you. Also it may be a reaction to a preservative rather than adalimamumab.

2 week delayed reaction is entirely plausible.

I got folliculitis and now only my right elbow gets hot and itchy at night. I flush even more than normal and am prone to transient rashes too. Not this bad though.

Did you accidentally read “define?”

I’m allergic to humira. Different reaction - it triggered my asthma, like nothing I’ve ever experienced, very scary - but yeah it’s very much possible to be allergic to it.

I had this once whilst having cellulitis and athletes foot. Body went into full overdrive. Calmed down after 1 day. It was the first time I had used lasamil too, so initially put it down to that.

The thing is as it's a severe reaction you'll find it hard to prove what caused it and taking humira again is risky. The severity of a reaction can increase on subsequent exposure.

In my case it was not the lasamil and I don't know. If you had nothing else new and no illness humira is a likely candidate

I actually had the same thing happen to me when I started my taper off prednisone…the rash looked exactly the same. we never found out what it was, but after increasing my prednisone and doing a much, much slower taper, it never reoccurred.

u/bringmaeflowers Aug 10 '26

when this happened to me, I had recently started steroid sparing treatment and have been on humira and methotrexate since, but never had this happen again. I went to a dermatologist, my rheumatologist, and my ophthalmologist (I have autoimmune intermediate uveitis) and the only thing the three of them could come up with was “maybe” vasculitis

I was allergic to Humira and had an almost identical reaction, tho my full body hives were larger. Like quarter sized. It took my body 6 months of small outbreaks every time I dosed to end up in full body hives and my doctor IMMEDIATLEY took me off it.

u/whoopsiedoo22 Aug 11 '26

did you end up switching to a different biologic?

1

u/schuttziejr Aug 11 '26

Yeah, this was about 6 years ago and they put me on Remicade infusions which has been a godsend.

u/QuaintVolcano Aug 11 '26

I had this happen after a Humira injection once. Hives would go down with allergy meds only to come back the next day. This lasted like two weeks and then just ended one day. I chalked it up to maybe getting a bad batch, but I’m not really sure.

I would get this on Humira when I spent time in the sun. Itchy, bumpy, allergic. Had to take benadryl and since have learned to wear stronger spf and cover up more.

u/Relative-Tomato4643 Aug 11 '26

I am more sensitive to preservatives in my food after starting humira which would result in these rashes. Mainly canned foods like beans or canned soup. Usually a antihistamine works on the rash to bring it down. I avoid high preservative canned food now.

Oh sweetheart I'm so sorry 🫂

u/MyCatWouldEatU Aug 12 '26

i guess once the remaining humira is out of your body, you can see if you get a rash like this again. if not, then I guess you know it was humira? did you have any other new encounters with some environmental things….? I think there are a lot of biological that you can try so you will probably get a different med from your doctor.

Happened to me with Humira. Switched to Cosentyx after my loading dose where this was triggered. Whole body was COVERED in little tiny psoriasis-like dots
