Which of the following products can be safely taken by pregnant women for heartburn and acid reflux?

Aluminium hydroxide is considered a safe option for managing heartburn and acid reflux in pregnant women. It works as an antacid, neutralizing stomach acid and providing relief from symptoms like heartburn and indigestion.

The safety of aluminium hydroxide during pregnancy is supported by its minimal systemic absorption, which means it is unlikely to reach the fetal circulation in significant amounts. Because it has a long history of use during pregnancy, healthcare providers often recommend it as a suitable treatment option.

In contrast, other choices may pose risks. Bismuth subsalicylate contains salicylate, which is generally avoided during pregnancy due to potential risks of bleeding or other complications. Aspirin is also contraindicated during pregnancy, particularly in the third trimester, due to similar concerns about bleeding and its effect on fetal development. Lansoprazole is a proton pump inhibitor that, while sometimes prescribed, might be approached with caution in pregnancy depending on individual circumstances and potential risks versus benefits.
