Firstly, it’s hard to give advice on a forum that is so paternalistic we’re not allowed to be specific about medication. Secondly, an allergic reaction is a specific IgE type reaction to a specific ingredient. So unless you have tried every single medication available (we’re talking literally dozens) and have had a severe allergic reaction to them all, you don’t know that you will have an allergic reaction to a new medication, because each medication is different and so will require you to have a new different specific allergic reaction to that new medication, too. So basically from a medical perspective, your story does not make sense.
I’d start by confirming with your doctors that you have had an IgE mediated true allergic reaction, and to exactly what medications, because I suspect there’s some bullshitting going on, because your story just isn’t making medical sense! I’m saying this because lots of people think they’re allergic to meds when they’re actually not, when it comes down to it.
Adverse reactions… they’re common, but they’re not allergic reactions!
