Hi,
Just spotted this. I too have reactions to drugs. Luckily I am safe with penicillin but there have been several anti-biopics which caused me to vomit repeatedly, and one caused an all over rash after I stopped the course.
In the ER last year, for a fall, and I was given straight codeine, had to be put on a drip to recover my BP dropped so much, but I am OK if the codeine is combined with paracetamol. I have heard that reactions to codeine are common.
I also had a reaction to the AZ Covid 19 vaccine.
No idea why I am so sensitive to stuff, but, when I was supposed to have surgery last year, they gave me a red wrist band to highlight that I was, instead of a normal white one.
Aside from this I have seasonal allergies but those did not appear until after I left my FOO home, the same time that my menstrual cycle became regular.
I am a firm believer that The Body Keeps The Score, but I do not really understand how.
Unfortunately, with drug reactions, the only way you find out is to have the drug, and the reactions can be unpleasant and debilitating.
