Hi Bw,
My heartburn and reflux were incredibly bad;making me vomit several times a day because of the rising acid in the back of the throat. it would sting and make my eyes water. I tried,tums,mylanta,quickeze and sea bands. None of them worked. I have had it for the entire pregnancy but it was gradually getting worse as i got bigger. Saw my ob two weeks ago and she prescribed zantac;drug name ranitidine. It is a b1 as others have said. My ob said it was fine though to use during pregnancy;maybe because the vomitting was making me lose weight? When i spoke to my very young pharmacist he said it still hadnt been sufficiently tested on humans to provide accurate data as yet. I decided to go with the opinion of my ob;and have had only a couple of vomitting occassions now when my blood sugars have been too low. Good luck with your ob;hope you feel better soon.
