I take 100 ml of sertraline daily. Recently, it has given me severe heartburn, to the point I vomit the medication. I’ve tried taking it during the day, instead of before bed, but still have same painful heartburn that upsets my stomach. I do not see heartburn listed as a side effect. Also, I’ve taken this medication for the last 16+ years. Not sure cause or if switching meds is wise. Thoughts.
