Indigestion
"I took Prilosec for about 3 years. I began to experience a rapid heartbeat at night. I would wake up at night and have very rapid heartbeat for about 5 minutes. It finally dawned on me to try leaving off the Prilosec. I have been off now for 2 months and am having no more problems with my heart. I found that Pepcid is also good for indigestion and causes me no problem."
