Yes they all brought on a rash which just got more and more itchy over time until I was covered in the rash. It was hard to tell if the rash was eczema, which I can get anyway, but the distribution of it was unlike my regular eczema. The rash broke through again when I had to take a higher dose of ppi.
I tried Omeprazole, pantoprazole and Lansoprazole. I had other side effects on Omeprazole (dizziness in particular) and I would say Lansoprazole has been a slightly better friend to me than the other ppis, but without the olive oil discovery I would be struggling with that too.
I do have food allergies and I never worked out whether I was having an allergic reaction to an excipient (drug packacking or colourings) or a pharmacological reaction to the drug itself. Either way, I still wish I didn't have to take it!
