I began taking 40mg 4 days ago and feel horrible. I was originally taking 20mg for severe headburn which I tolerated. I vomit everyday, can't sleep, feel very anxious, can't eat, stomach is very queasy. I didn't take it today but I still vomited, feel anxious, depressed and have severe headburn.
Hi, you seem to be having a severe reaction to this increased dose. I was taking Omeprazole 20mg for a long time, for the same reason as you. I also had a dose increase to 40mg, but switched to Nexium, which is in the same drug class. I have made myself aware of any side effects that i may encounter, and what you are experiencing falls in to this category. I would urge you to see your doctor asap and don't take any more of the medication in the meantime
