Omeprazole
indigestion
"I've been taking this medication daily and it has worked wonders for my indigestion. Started waking up with hives pretty bad about once or twice a week a couple of months ago and have had some instances where my lips swell.  Had to take Benadryl.  Didn't realize it, but that is one of the side effects of using this medication.  A little afraid to continue using it but sure hate the thought of not using it."
