I take prilosec for my acid reflux
I always carry tums around with me, its safe to take up to 7 a day during pregnancy :)
You can even take tums like 10-15 minutes before you eat to lessen the chance of getting heartburn from food.
Drink a cold glass of milk then take tums that works for me......
If tums dont work zantac 75 is safe. I had to switch to that at 30w because I kept having to take too many tums, which can cause gaul stones :-/
I take tums, its perfectly safe.
