I was feeling hungover, turns out...

I posted a while back that I was feeling hungover when I woke up then much of the day I was nauseated, dizzy, no energy. I just wanted to lay down all the time. Turns out I may have been allergic to Omeprazole. I switched to Zantac and it made a huge difference. I still struggle, I think with low blood sugar, but its not a battle like it was. YAY!

Wow, glad to hear you found out what was causing your illness. Odd how different medicines react on us.

With due respect, those symptoms (nausea, dizziness) are not symptoms of a drug allergy. Drug allergies produce itching, hives, and (in bad cases) anaphylaxis -- an inability to breathe, which can be fatal.

I'm not sure what your symptoms would represent. It's possible that the omeprazole was causing upset stomach due to blocking too much acid, but usually blocking acid causes the opposite effect (ie, it's the acid that causes the nausea, etc.)

Since you mentioned hypoglycemia, I should note that both symptoms (nausea and dizziness) can be caused by hypoglycemia. It's possible that when you resolved the hypoglycemia just happened to coincide with switching the acid blockers.

Bottom line is that I'm glad you're feeling better, but you should be careful with the term "drug allergy" since I'm pretty sure this isn't one...

Perhaps I should have said I suffered from an adverse reaction, all listed under the side effects that I should have read more closely to begin with. I have not been diagnosed with hypoglycemia but was advised by my dietician that my high Protein diet needed to be better balanced.
