I don't know, but my dr said tums are safe to take, so i been taking tums
Tums aren't working for me :(
Pepcid is ok and so is zantac
Mylanta is safe. They have it to me at the hospital one night. Just follow the directions on the bottle. It tastes nasty, but works so well.
You could also try plain vanilla or chocolate ice cream or some milk. Dairy neutralizes the acid naturally. That's what I do when I run out of tums in the middle if the night.
My doctor prescribed me pepcid
