Taking 300mg of lithium daily along with 10mg Celexa.  Somedays seem to feel heart beat or pounding and sensation similar to heartburn, not always concurrently.  I have been battling depression for over a year now.  Should I be concerned about this?  Male, non smoker, 49 Yr old
Thanks for your question on Chat Doctor. I can understand your situation and problem. Lithium can cause heart burn. So you might be having side effect of lithium. But better get done ECG to rule out cardiac cause for your chest discomfort. So get done ECG first. If ECG is normal then no need to worry much for cardiac cause. You are having mostly heart burn. Depression can itself cause worsening of heart burn. So control of depression is must. Better to consult psychiatrist and discuss all these and try to treat depression first. For heart burn start Proton pump inhibitors. Avoid stress and tension. Avoid hot and spicy food. Don't worry, you will be alright. Please hit, thanks.
