question: I had racing heart and increased irrgular heartbeat with anxiety when I tried Nexium 4 years ago. Since then I take aloe and have not had symptoms of GERD or acid reflux. Now my dr. wants to give me Dexilant 60 mg. I can t find out if the same thing that cuases it in nexum is in Dexilant. Can you help. The Dr. said I have Gastritis, possible due to my hietal hernia.
