Have a relative who has had to take Nexium daily for over 10 years to help with controlling heartburn from Gastroparesis and all the proton pump meds seem to have the same kidney problems. Is there any known med they can switch to to get relief from their pain without risking kidney damage "if" their kidneys are not already damaged? Why do their Endocrinologists prescribe Nexium if it is so dangerous? She has been a type 1 diabetic for approx. 36 years! Zantac and the safer drugs do no seem to help with the Gastroparesis and heartburn attacks. Thank you.
