Antacids are generally regarded as safe but should you use them in pregnancy? Most antacids are safe during pregnancy but before you take any antacids consult your doctor.

All antacids work by neutralising acid in the stomach so that the refluxate in the esophagus is less acidic and unlikely to cause heartburn.

Antacids do not cross the placental barrier. In other words it does not get into the blood circulation of the foetus. They, therefore, cannot harm the baby. They are all grouped in Category A. Drugs in this group will not injure the foetus.

Avoid antacids containing sodium bicarbonate. The high sodium content could cause fluid retention. It can also trigger secondary acid secretion and make problems with gas worse.

Antacids containing magnesium can delay, slow down or stop labour. Aluminium containing antacids can make constipation during pregnancy worse.
