Heartburn - help!

Whichever PPI you start, make sure you take it on an empty stomach, and wait a minimum of 30-60 minutes to eat anything. Also, sometimes PPIs take a few days to kick in, for immediate relief try to avoid Tums/Rolaids since they have calcium carbonate and that can cause rebound reflux. Gaviscon is what has been recommended if I have breakthrough reflux.

I was on Prilosec 20mg once daily. Now, I'm on Nexium 40mg in the pregnancy.
