Yes many allergies to many meds including antibiotics.
Also many food allergies.

Yes!

Most definitely yes and I would say more so, than normal

I have too many allergies to both foods & medications.
I believe that’s quite common for us.

I also had allergic reaction to anti-depressant but you have to find one that works for you I found one and I got out of massive depression. I had taken Effexsor, I had diarrhea and went down to 85 pounds so my doctor changed Desipramine 50 mg & Seroquel - Quetiapine XR 150 mg. for major depression. it takes time and you need to focus on you.
So fon’t give up hope.
