I started taking OMEPRAZOLE on April 1 and stop taking it on April 9 due to my heart started feeling like it was in my throat. I'm of balance, high pulse rate, dizziness, and rapid spells of burping. Before taking this medication I was having some stomach problems and was prescribed this medication to clear them up but once I started taking it, I started feeling even worse. I ended up in the ER and had multiply doctors appointment within a week of taking this medication. I had a EKG and everything was normal but I feel like crap.
