It's standard treatment to do iv solumedrol prior to remicade when you have already had an allergic reaction.
Tylenol and Benadryl are comfort measures (itching fever etc..)
But will not stop anaphylaxis
Your child is at very high risk of anaphylaxis to remicade now.
The steroids will calm his immune system some so if he reacts again it MAY be less severe .
Anaphylaxis can only be stopped with epinephrine when given early enough some times
But other times it progresses to anaphylactic shock or death .
It's like labor once your child's body has done it once the second time it's quicker and faster
Symptoms
Anaphylaxis symptoms occur suddenly and can progress quickly. The early symptoms may be mild, such as a runny nose, a skin rash or a "strange feeling." These symptoms can quickly lead to more serious problems, including:
Trouble breathing
Hives or swelling
Tightness of the throat
Hoarse voice
Nausea
Vomiting
Abdominal pain
Diarrhea
Dizziness
Fainting
Low blood pressure
Rapid heart beat
Feeling of doom
Cardiac arrest
People who have had a severe allergic reaction are at risk for future reactions. Even if your first reaction is mild, future reactions might be more severe. That's why it's important to carry self-injectable epinephrine if you are at risk, and 911 should be dialed in the event of a very serious reaction.
Understanding anaphylaxis and the things that can trigger this severe allergic reaction will help you manage your condition.

Benadryl is like a flight attendant during a plane crash
They make the passengers feel better but don't stop the crash
Anaphylaxis is having more than one system involved your child had more than one last time and thankfully it stopped in its own .
Ds has had anaphylaxis to foods and bees.
He has also had a allergic reaction to remicade
We tried again later with remicade and gave iv solumedrol prior and he still reacted
So he was switched to humira since they knew the odds of severe reaction that they may not be able to stop was too great
They should have explained the risk to you
Please consult your child's GI
Ds had allergic reaction to contrast dye and glacogen /galullidium during and MRE
So he was pre treated with iv steroids with multiple doses for the day prior and then right before his scan .
He was ok during the scan -no major reaction
But not something any of us or the doctors want to repeat unless absolutely necessary
Good luck
And talk to your doc
