be careful...i broke out in hives from head to toe..
Diarrhea and constipation can be side-effects. Some people get tingling. If it's severe, check with your doc and try another PPI. They're not all alike.
I think I am allergic to the Prevacid too or something. And most everything else that i have tried to take for my Acid Reflux and GERD... I think mine is related to hypothyroidism........... What can I do?
