If a pregnant patient does not respond to nonpharmacologic therapy, antacids are first-line therapy, and patients should choose a nonsystemic low-sodium product such as hydroxymagnesium aluminate (Magaldrate). Alka-Seltzer contains baking soda and can be harmful during pregnancy. A histamine2 receptor antagonist, such as Pepcid, may be used, but only if recommended by the provider. TUMS contain calcium, which can be constipating during pregnancy.
