Regardless you should definitely take medicine advise from your ob. Some ob's say different stuff about different medicines or foods. It's best to go by what your doctor says. Maybe shoot them an email?

@babyvicky2016, yeah my OB switched me to Zantac 150 twice a day. plus I take tums like crazy! the heartburn sucks😢

Not sure sorry. But I was prescribed Zantac by my Ob and it works great.

that's what I thought. My primary doctor took me off of it at the beginning and put me on Zantac. I seen a new OB today(mind had an emergency) and he wanted me back on Nexium. I looked it up and it said its not known if it can harm baby. I'm just gonna stick with Zantac.

zantac is, I don't think nexium was recommended.
